If you are hoping to see some meteors from the Quadrantid meteor shower but are being foiled by cloudy weather or if it’s just too cold outside to get up off your couch, NASA has come to the rescue. The Marshall Space Flight Center has set up a live all-sky camera feed of the skies over Huntsville, Alabama in the US. You can find the Ustream page with the feed here. Reports from Marshall say the weather looks very clear for tonight (Jan. 3) in Huntsville. Tonight is really your best shot to see this meteor shower this year.
If you plan to be a little more actively involved in watching this shower, join in on Meteorwatch, where you can share the experience via Twitter.
Of course, you will have to wait until it is dark in Huntsville to watch the video feed; during the daytime, the feed will just show a dark gray box. The camera is light-activated and will turn on at dusk each evening.
This shower will peak in the early morning hours of Jan. 4. The Quadrantids have a maximum rate of about 100 per hour, varying between 60-200. The waxing gibbous Moon will set around 3 a.m. local time, leaving about two hours of excellent meteor observing before dawn.
Here’s a map of who should be able to see the Quadrantid meteors:

Red areas will see no Quads, yellow just a few, and green should see a decent shower if they are in dark sky conditions.
Marshall Space Flight Center suggests that to view tonight’s Quadrantids, you should have an area with dark skies well away from city or street lights. Dress warmly and go out just after Moonset around 3 a.m. local time. Lie flat on your back on a blanket, lawn chair, or sleeping bag and look up, taking in as much of the sky as possible. After about 30 minutes in the dark, your eyes will adapt and you will begin to see meteors. Be patient — the show will last until dawn, so you have plenty of time to catch a meteor.

The first of the 2012 meteor showers – The Quadrantids – peaks on the night of the 3rd and 4th of January.
The Quadrantid meteor shower is one of the major annual meteor showers and often performs well under ideal observing conditions.
The Quadrantids can be quite impressive with a Zenithal Hourly Rate (ZHR) of up to 120 meteors per hour at their peak (under perfect conditions) and can sometimes produce rates of 60 to 200 meteors per hour. The peak is quite narrow lasting only a few hours, with activity either side of the peak sometimes being weak, but well worth observing.
Due to a waxing gibbous Moon, the best time to look is after midnight and through the early hours, plenty of time for us to see the peak build up to 07:20 UT on the 4th, but the Quadrantids are active from December 28th through January 12th so we should have plenty of chances to spot some shooting stars.
The radiant of the Quadrantids (where the meteors radiate from) is in the constellation of Boötes, however many people are misled in thinking they need to look at the radiant to see the meteors – this is not true. Meteors will come from the radiant, but will appear anywhere in the whole sky at random. You can trace the meteors (shooting stars) path back to the radiant to confirm if it is a meteor from the meteor shower.
You don’t need a telescope or binoculars to watch meteor showers, just your eyes. To enjoy a meteor shower and spot as many meteors as possible, you need to try and place yourself away from bright lights and make yourself comfortable. Meteor showers are best observed if you use a reclining garden chair or something similar so you can keep your gaze on the sky as long as possible. This will give you the best results.

January brings us striking views of the night skies! You’ll be able to see well known constellations during the long hours of darkness in the Northern hemisphere, with crisp cold skies. This is an ideal time to get out and look at the wonders of the night sky as there is so much to see for the beginner and seasoned astronomer alike.
You will only need your eyes to see most of the things in this simple guide, but some objects are best seen through binoculars or a small telescope.
So what sights are there in the January night sky and when and where can we see them?

As soon as the month starts we receive a welcome treat in the form of the Quadrantid meteor shower on the evening of the 3rd/ morning of the 4th of January.
The Quadrantids can be quite an impressive shower with rates (ZHR) of up to 120 meteors per hour at the showers peak (under perfect conditions) and can sometimes produce rates of up to 200 meteors per hour. The peak is quite narrow lasting only a few hours, with activity either side of the peak being quite weak.
Due to a waxing gibbous moon, the best time to look is after midnight and through the early hours when the moon sets in time for us to see the peak which is 07:20 UT.
The radiant of the Quadrantids (where the meteors radiate from) is in the constellation of Boötes, however many people are mislead in thinking they need to look at the radiant to see the meteors – this is not true. Meteors will come from the radiant, but will appear anywhere in the whole sky at random. You can trace the shooting stars path back to the radiant to confirm if it is a meteor from the meteor shower.

Planets
Mercury is low down in the southeast before sunrise in the first week of January.
Venus will be shining brightly in the southwest until May and will pass within 1° of Neptune the furthest planet on the 12th and 13th of January. You can see this through binoculars or a small telescope. On the 26th Venus and the Moon can be seen together after sunset. Venus
On the 5th of January, Earth will be at “Perihelion” its closest point to the Sun.
Mars brightens slightly to -0.5 during January and can be found in the tail of Leo; it can be easily spotted with the naked eye. The red Planet is close to the Moon on the night of the 13th/ 14th January. Mars
On January 2nd Jupiter and the Moon will be very close to each other with a separation of only 5° with Jupiter just below the Moon. Jupiter will continue to be one of the brightest objects in the sky this month. Jupiter
Saturn now lies in the constellation of Virgo and follows after just after Mars in Leo. Saturn
Uranus is just barely visible to the naked eye in the constellation of Pisces and can be easily spotted in binoculars or small telescopes throughout the month. The Moon will pass very close to Uranus on the 27th and will be just 5.5° to the left of the planet. Uranus Moon phases

Constellations

In January the most dominant and one of the best known constellations proudly sits in the south of the sky – Orion the hunter.
Easily distinguishable as a torso of a man with a belt of three stars, a sword, club and shield, Orion acts as the centre piece of the surrounding winter constellations. Orion is viewed upside down in the Northern sky as seen from the Southern hemisphere.
Orion contains some exciting objects and its most famous are the Great Nebula in Orion(M42), which makes up the sword and is easily seen in binoculars or a telescope and bright Betelgeuse, Orion’s bright alpha star (α Orionis). Betelgeuse is a red supergiant many times larger than our Sun; it would engulf everything in our solar system out to the orbit of Jupiter, if the two stars swapped places. Betelgeuse will eventually end its life in a Supernova explosion and some people believe that it may have already exploded and the light hasn’t reached us yet. It would make for a fantastic sight!

If you draw an imaginary line through the three belt stars of Orion and keep going up and to the right, you will come to a bright orange coloured star – Aldebaran (α Tauri) in the constellation of Taurus. Pleiades Cluster/ Seven Sisters
Taurus depicts a head of a bull with Aldebaran as its eye with a V shape that creates long horns starting from what we call the Hyades cluster, a V shaped open cluster of stars. If you continue to draw a line through the belt stars of Orion, through Aldebaran and keep going, you will eventually get to one of the gems in Taurus – The Pleiades cluster or Seven Sisters (M45) a stunning cluster of blue and extremely luminous stars and from our vantage point on Earth, the most recognisable cluster with the naked eye. A great object to scan with binoculars. A great object to hunt for with a small telescope is the Crab Nebula (M1) near the end of the lower horn of Taurus. The Crab Nebula
If you go back to our imaginary line drawn through the belt stars of Orion and draw it in the other direction, to left and below, you will come to the very bright star Sirius (α CMa) – The Dog Star in Canis Major. Sirius is the brightest star in the sky and is only 8.6 light years away, it is the closest star visible to the naked eye after the Sun.
Sirius along with Betelgeuse and Procyon (α CMi) in Canis Minor, form an asterism known as the Winter Triangle.
Directly above Orion and the Winter Triangle are the constellations of Gemini (The Twins), with the two bright stars of Castor and Pollux marking their heads and Auriga the charioteer, with its bright alpha star Capella (α Aur). Auriga is host to M36, M37 and M38 which are globular clusters and easily seen through binoculars or small telescope and Gemini plays host to M35. M37
Only a few of the objects available to see have been mentioned, so get yourself a good map, Planisphere or star atlas and see what other objects you can track down!
As 2011 is drawing to a close, the festive season is here and many of us are winding down and looking forward to the holidays. But this is a great time to look ahead to 2012 and pencil into our calendar and diaries the top astronomical events we don’t want to miss next year.
2012 is going to be a great year for astronomy observing, with some rare and exciting things taking place and a good outlook with some of the regular annual events.
So what top wonders should we expect to see and what will 2012 bring?
Conjunction of Venus and Jupiter Venus & Jupiter Conjunction Credit: Anthony Arrigo UtahSkies.org
On March 15th the Planets Venus and Jupiter will be within 3 degrees and very close to each other in the early evening sky. This will be quite a spectacle as both planets are very bright (Venus being the brightest) and the pair will burn brightly together like a pair of alien eyes watching us after the Sun sets.
This conjunction (where planets group close together as seen from Earth) will be a fantastic visual and photographic opportunity, as it’s not often you get the brightest Planets in our Solar System so close together.
Transit of Venus Transit of Venus Credit: Australian Space Alliance
For many, the transit of Venus is the year’s most anticipated astronomical event and it takes place on June 5th – 6th. The Planet Venus will pass between the Earth and the Sun and you will see Venus (a small black circle) slowly move across, or “transit” the disc of the Sun.
Transits of Venus are very rare and only a few have been witnessed since the dawn of the telescope. Be sure not to miss this very rare event as the next one isn’t visible for over another 100 years from now in 2117 and the next after that is in 2125.
The full transit of Venus in 2012 will be visible in North America, the northwest part of South America, Western Pacific, North East Asia, Japan, Australia and New Zealand. Other parts of the world will see a partial transit such as observers in the UK, who will only be able to see the last part of the transit as the Sun rises.
First contact will be at 22:09 UT and final contact will be at 04:49 UT
Take note! You have to use the right equipment for viewing the Sun, such as eclipse glasses, solar filters, or projection through a telescope. Never ever look directly at the Sun and never look at it through a normal telescope or binoculars – You will be permanently blinded! The transit of Venus will be a very popular event, so contact your local astronomy group and see if they are holding an event to celebrate this rare occasion.
Meteor Showers Don't Miss the Major 2012 Meteor Showers Credit: Shooting Star Wallpapers
2011 was a poor year for meteor showers due to the presence of a largely illuminated Moon on all of the major showers; this prevented all but the brightest meteors being seen.
In contrast 2012 brings a welcome respite from the glare of the Moon as it gives little or no interference with this year’s major showers. The only other issue left to contend with is the weather, but if you have clear skies on the evenings of these celestial fireworks, you are in for a treat.
The Quadrantid Meteor Shower peak is narrow and just before dawn on January 4th this shower is expected to have a peak rate (ZHR) of around 80 meteors per hour.
The Perseid Meteor Shower peak is fairly broad with activity increasing on the evenings of the August 9th and 10th with the showers peak on the morning of the 12th. Perseids are the most popular meteor shower of the year as it tends to be warm and the shower has very bright meteors and fireballs, with rates of 100+ an hour at its peak.
The Geminid Meteor Shower is probably the best meteor shower of the year with high rates of slow bright meteors. The peak is very broad and rates of 100+ meteors per hour can be seen. The best time to look out for Geminids is on the evenings of the 12th to 14th December, but they can be seen much earlier or later than the peak.

Jupiter and the Moon Occultation of Jupiter by the Moon on July 15th as seen from Southern England Credit: Adrian West
European observers are in for a very rare treat as the Moon briefly hides the planet Jupiter on the morning of July 15th. This “lunar occultation” can be seen from southern England and parts of Europe at approximately 1:50am UT (dependant on location) and the planet re-emerges from the dark lunar limb at approximately 3:10am UT.
This is a great chance to watch this rare and bright event, and it will also be a fantastic imaging opportunity.
Annular Eclipse Annular Eclipse Credit: Kitt Peak Observatory
American observers will have treat on May 20th with an annular eclipse of the Sun. The eclipse will be visible from many western US states and a partial eclipse visible from most of North America.
Because the Moon’s orbit is not a perfect circle and is slightly elliptical, it moves closer and further away from us slightly in its orbit by 13% and on July 15th it is at its furthest point away from the Earth as it passes in front of the Sun.
Normally the Moon covers the entire disc of the Sun and creates a total solar eclipse, but because the Moon is at its furthest point in its orbit on the 15th, we get an annular eclipse, where we can still see a ring of bright light around the Sun, but we don’t get totality.
The eclipse starts roughly at 6:20pm local time for the Western US states and lasts for four and a half minutes.
As mentioned earlier; never, ever look at the Sun without proper protection such as eclipse glasses or filters for equipment! This can damage your eyes and permanently blind you. This is the same for cameras; the sensitive chips inside can be damaged.
The World Not Ending
End Of The World
Finally we get to December 21st, in which astronomy-minded folks will celebrate the solstice. But in case you haven’t heard, some have prophesied the end of the world, saying the Mayan calendar ends. This has been the subject of much discussion, comedy and media coverage, and it has even been made into films.
Will the Antichrist press the red button and will there be the Rapture? Will the Earth reverse its magnetic poles, or will we get wiped out by a solar flare, rogue comet or asteroid?
Nope, probably not. You can read our entire series which explains why this whole 2012 end-of-the-world craze is complete hokum.
All I know is 2012 is going to be a great year for astronomy with some very interesting, rare events taking place, with many more regular events to see, as well.

Have you been watching the Geminid Meteor Shower? With just hours to go before the peak, activity has been high – despite this year’s Moon! If you’d like to know more on the history of this meteor shower, then check out this great article by Adrian West. If you plan on watching and would like to do something cool and unusual, then step inside…
As you can see from this below video sent to us by John Chumack, even the bright moonlight isn’t interfering too badly with this year’s awesome Geminid meteor shower display. While it will make the fainter ones more difficult to observe, the “fireball” attitude of this meteor shower just won’t quit!
As a reminder, be sure to be out tonight and through tomorrow morning for the peak of the show. You’ll want to try when the skies are the darkest, begin before moonrise – but don’t forget the display is usually the greatest around 2:00 a.m. local time when the sky window is pointed in the optimum direction. Just look along the ecliptic plane and follow the constellation of Gemini as it cruises roughly east to west across the sky as the night goes on! If you get clouded out? Try again the next night… and the next. The stream for the Geminids is very broad and lasts for some time.
Now… if you really want to have some fun and have an iPhone, here’s a real treat…
Thanks to NASA, there’s a new application which will help you to track, count and record information about this meteor shower and any meteor shower in the world – including sporadic ones! The “Meteor Counter” app will allow you to record your observations with an easy-to-use “piano key” interface. As you strike the keys, the app records information for each meteor, including the brightness and time. Once your observing session ends, your information and data is automatically uploaded to NASA researchers for analysis.
Created by Dr. Bill Cooke, head of NASA’s Meteoroid Environment Office at NASA’s Marshall Space Flight Center and the one-and-only Dr. Tony Phillips of SpaceWeather.com, this new iPhone application is going to change the way you observe and help science, too. “We developed the iPhone app to be fun, and informative, but also to encourage going outside to observe the sky,” said Cooke. “Our hope is the app will be useful for amateur and professional astronomers — we want to include their observations in NASA’s discoveries — and have them share in the excitement of building a knowledge base about meteor showers.”
The app is more than just a set of keys, though… It has an optional recorded audio track and users can even add their own comments as they observe. This will all be sent to NASA along with the numbers – vital information which will help researchers identify meteors associated with specific radiants and one-time events. The “Meteor Counter” was designed with everyone in mind – from the beginner to the expert – and even those who have never seen a meteor before. “The beauty is that it gradually transforms novices into experts,“ says Cooke. “As an observer gains experience , we weigh their data accordingly in our analyses.”
The Meteor Counter app is also much more. It provides a newsfeed and event calendar that’s kept up-to-the-moment by professional NASA and meteor scientists, and it will help keep you informed of upcoming meteor showers and the most current sightings. The app is currently available for iPhone, iPad and iPod Touch. Download the free app at : http://itunes.apple.com/us/app/meteor-counter/id466896415. A version for other mobile devices will be available in the near future. Complete instructions for using the Meteor Counter app is available at: http://meteorcounter.com/ and more information about NASA’s Meteoroid Environment Office can be found at: http://www.nasa.gov/offices/meo/home/index.html.

It’s the finale of this year’s meteor showers: The Geminids will start appearing on Dec. 7 and should reach peak activity around the 13th and 14th. This shower could put on a display of up to 100+ meteors (shooting stars) per hour under good viewing conditions.
However, conditions this year are not ideal with the presence of a waning gibbous Moon (which will be up from mid-evening until morning). But seeing meteors every few minutes is quite possible. Geminid meteors are often slow and bright with persistent coloured trails which can linger for a while after the meteor has burned up.
There is something unusual about the Geminid meteor shower, as normally meteor showers are caused by the Earth ploughing through the debris streams created by comets and their tails. But the object that created the specific stream of debris associated with the Geminids is not a dusty icy comet, but a rocky asteroid called Phaethon 3200.
Phaethon 3200 belongs to a group of asteroids whose orbit cross the Earth’s. It turns out to be an unusual member of that group: Not only does it pass closer to the Sun than the others but it also has a different colour, suggesting a different composition to most asteroids. Credit: Adrian West
One of the curious things about the Geminid particles is that they are more solid than meteoroids known to come from comets. This is good for meteor watchers; giving us brighter meteors.
Observations by astronomers over decades have shown that meteor rates have increased as we reach denser parts of the stream.
It is not known exactly when the asteroid was deflected into its current orbit, but if it was originally a comet it would have taken a long time for all the ices to have been lost. However, it is possible that it may have been a stony asteroid with pockets of ice.
We are unsure of the origins and appearance of Phaethon 3200, but its orbit has left us with a unique legacy every December, with little steaks of light known as the Geminid meteor shower.
You will only need your eyes to watch the meteor shower, you do not need telescopes binoculars etc, but you will need to be patient and comfortable. See this handy guide on how to observe meteors
During a meteor shower, meteors originate from a point in the sky called the radiant and this gives rise to the showers name e.g. The Geminids radiant is in Gemini, Perseids radiant is in Perseus etc.
Don’t be mislead by thinking you have to look in a particular part of or direction of the sky, as meteors will appear anywhere and will do so at random. You will notice that if you trace back their path or trajectory it will bring you to the meteor showers radiant. The exception to this rule is when you see a sporadic or rogue meteor.
Tell your friends, tell your familly and tell everyone to look up and join in with the Geminid meteorwatch on the 12th to the 14th December 2011.

Are you ready for a good, predictable meteor shower? Then break out your favorite skywatching gear because the 2011 Leonid meteor shower is already sparkling the skies…
In the pre-dawn hours on the mornings of November 17-19th, the offspring of Comet Temple/Tuttle will be flashing through our atmosphere at speeds of up to 72 kilometers per second – and enticing you to test your meteor watching skills against partially moonlit skies. Although the waning Moon will greatly interfere with fainter meteor trails, don’t let that stop you from enjoying early evening observations, or enjoying your morning coffee with a handful of “shooting stars” which will be emanating outward from the constellation of Leo.
Where in the skies do you look? For all observers the constellation of Leo is along the ecliptic plane and will be near its peak height during best viewing times. When? Because of the Moon, earlier evening observations are favored (before local midnight), but just a couple of hours before local dawn is the best time to watch. Why? Read on!
Although it has been a couple of years since Temple/Tuttle was at perihelion, don’t forget that meteor showers are wonderfully unpredictable and the Leonids are sure to please with fall rate of around 20 (average) per hour. Who knows what surprises it may bring! Each time the comet swings around our Sun it loses some of its material in the debris trail. Of course, we all know that is the source of a meteor shower, but what we don’t know is just how much debris was shed and where it may lay.
“The Moon is going to be a major interference, but we could see a rate of about 20 per hour,” said Bill Cooke, head of NASA’s Meteoroid Environments Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “Some models, including ours, indicate that particles may encounter Earth on November 16 at around 5:30 p.m. EST [2230 GMT], where we could see anywhere from 100 to 200 meteors per hour. So, we could get a Leonid outburst, but unfortunately it is not favorably placed for viewing from the United States.”
As our Earth passes through the dusty matter, it may encounter a place where the comet let loose with a large amount of its payload – or it may pass through an area where the “comet stuff” is thin. We might even pass through an area which produces an exciting “meteor storm” like the Leonids produced in 1883! For those in the know, the Leonid meteor shower also made a rather incredible appearance in 1866 and 1867 – dumping up to 1000 (not a typo, folks) shooting stars recorded even with a Moon present! It erupted again in 1966 and in 1998 and produced 3000 (yep. 3000!) video recorded meteors during the years of 2001 and 2002. But remember, human eyes may only be able to detect just a few. So what’s a realistic guess?
According to Cooke; “We could see rates of about five meteors per hour,” he explained. “If people want to see the Leonids, it might be good to watch the nights of November 16th and 17th. Instead of just going out one night, you might want to go out twice.”

And to make this year’s show twice as nice, you’ll have a hard time not being distracted with the Moon and Mars being right on the radiant! You won’t be able to miss the Red Planet as the Moon slides along south… First to Mars’ west and then to the east on the nights of November 18th and 19th.

“The weather was against us, it was raining heavily in the northern Norwegian town of Tromsø,” Adon describes on his Flickr page. “We drove for 2 hours and waited on the Norwegian/Finish border for 3 more and this was at the start of the show on October 19th.”
He adds, “I actually missed the shooting star when it happened, but my friend told me and I was eager to check the exposure when I got home.”
Orionid Meteor Shower: The above image shows brilliant multiple meteor streaks that can all be connected to a single point in the sky just above the belt of Orion, called the "radiant." The Orionids take place in mid-October and the parent comet is Halley. Comet Halley is actually responsible for two known meteor showers: The other is the Eta Aquarids, which are visible every May.

Do you hate to get up early? Then stay up late, because it’s infrequent that both the northern and southern hemispheres have a chance to catch an annual meteor shower. Right now the Earth is heading into the complex Orionid stream, and while the skies won’t be perfectly dark, they aren’t going to be bad. Where and when do you watch? Follow me…
As the Earth slowly orbits the Sun, it passes into one of the debris streams left by Comet Halley and the material returns as the Orionid meteor shower. While it won’t be a “meteor storm”, what you can expect to see is one of the most predictable and reliable meteor showers of the year. Even if it’s a few days early (or late), take advantage of any clear skies and begin your observations because activity is up.
The Orionids produce an average of 10-20 meteors per hour maximum, and best activity begins before local midnight on October 20th, and reaches its peak as Orion stands high to the south about two hours before local dawn on October 21st. With only partial slice of Moon in the late evening/early morning, this looks to be the year’s last, best meteor shower!
“Every year around this time Earth glides through a cloud of dusty debris from Halley’s Comet,” explains Bill Cooke of the NASA Marshall Space Flight Center. “Bits of dust, most no larger than grains of sand, disintegrate in Earth’s atmosphere and become shooting stars.”
“It’s not an intense shower,” he says, “but it is a pretty one.”
Although Comet Halley has now departed the inner Solar System, its debris trail remains well organized – allowing us to predict when this meteor shower will occur. The Earth first enters the stream at the beginning of October and does not leave until the beginning of November. This makes your chances of “catching a falling star” above average!
“Earth comes close to the orbit of Halley’s Comet twice a year, once in May and again in October,” explains Don Yeomans, manager of NASA’s Near-Earth Object Program at the Jet Propulsion Laboratory. Orionid meteoroids strike Earth’s atmosphere traveling 66 km/s or 148,000 mph,” he continued. These meteors are very fast, and although faint (average magnitude 3), occasional fireballs do leave persistent trails that shimmer in the upper atmosphere. It’s the “Oooooh!” effect!
For best success, get away from city lights. Face south-southeast in the northern hemisphere and almost overhead in the southern – then relax and enjoy the stars of the Winter Milky Way. The radiant is near Betelguese, but may occur from any part of the sky. When the Moon rises, try positioning yourself so a house, tree, or other obstruction helps to reduce the glare. The meteor watching experience is much more comfortable if you include a reclining lawn chair, blanket, and thermos of your favorite beverage. Nothing spoils watching quicker than “meteor neck”.
Clouded out? Don’t despair. You don’t always need eyes or perfect weather to keep the watch. Tune an FM radio to the lowest frequency that doesn’t receive a clear signal. An outdoor FM antenna pointed to the zenith increases your chances – but isn’t essential. Simply turn up the static and listen. Those hums, whistles, beeps, bongs, and occasional snatches of signals are distant transmissions being reflected off a meteor’s ion trail!

After weeks of speculation of its intensity, the Draconid/Giacobond meteor shower finally arrived. Some astronomers predicted that this normally quiet meteor shower would deliver up to 1000 meteors per hour at its peak – Were they right?
At approximately 20:00 BST (21:00 UT) on October 8th 2011 the shower started in earnest and many in the UK and Europe looked forward to an evening of meteor watching.
Unfortunately, many people were under thick clouds and missed the display, but there were a few places where the clouds cleared and observers were treated to a memorable spectacle.
I have done many meteorwatch evenings in the past, but this one got exciting very quickly and the uncertainty of the amount of meteors was soon doused.
Many people including myself were popping outside and trying to glimpse meteors through the clouds, but most of the time the Meteorwatch Meteor Live View was being used.
Everything was fairly sedate apart from us all moaning about the weather, but then all of a sudden at approximately 20:30 BST (19:30 UT) The Meteor Live View app on the Meteorwatch website went crazy!
Meteor Live View Credit: meteorwatch.org/ Norman Lockyer Observatory UK
Many people started to get good breaks in the clouds including myself and there were reports of dozens of meteors in just a few short minutes, much to the envy and disappointment of those still clouded over.
The evening continued and to everybody’s delight (to those who could see meteors), there were many. I saw 3 within a couple of seconds and this continued for about an hour.
Eventually rates started to decline, people saw less and the Meteor Live View started to show less activity.
At approximately 22:00 BST (21:00 UT) meteor activity dropped substantially – The show was over!
The IMO results were posted on their website with rates of just under 350 meteors per hour at the peak of the shower, reported by their observing stations. Credit: IMO
Did the Dracondids/ Giacobonids live up to expectations in the end? I would say yes, a fairly heavy meteor shower, maybe it could be called a mini storm!
