A Moment Frozen in Time On May 19th, 2005, NASA's Mars Exploration Rover Spirit captured this stunning view as the Sun sank below the rim of Gusev crater on Mars. This Panoramic Camera (Pancam) mosaic was taken around 6:07 in the evening of Sol 489. The terrain in the foreground is the rock outcrop "Jibsheet," a feature that Spirit has been investigating for several weeks (rover tracks are dimly visible leading up to "Jibsheet"). The floor of Gusev crater is visible in the distance, and the Sun is setting behind the wall of Gusev some 80 km (50 miles) in the distance. Credit: NASA/JPL-Caltech/Texas A&M/Cornell

But a decade ago, NASA’s six wheeled Spirit rover was but a promise of great things to come. And her rich Martian scientific heritage we know today was but a dream yet to ensue
Jan. 3 marks the 10th anniversary since her touchdown on Mars on Jan. 3, 2004. Her twin sister Opportunity soft landed 3 weeks later on Jan. 24, 2004.
So here’s a collection of some of Spirit’s greatest hits on the Red Planet for all to enjoy and remember her fabulous exploits.
Read my detailed new overview marking ‘Spirits 10 Years on Mars’ – here – with even more spectacular Red Planet imagery!

Since the golf cart sized Spirit snapped over 128,000 raw images, drove 4.8 miles and ground into 15 rock targets we can’t show everything.
Here’s a retrospective of some of our favorites.
In this selfie, Spirit shows her solar panels gleaming in the Martian sunlight and carrying only a thin veneer of dust two years after the rover landed and began exploring the red planet. Spirit’s panoramic camera took this mosaic of images on Sol 586 (Aug. 27, 2005), as part of a mammoth undertaking. The vertical projection used here produces the best view of the rover deck itself, though it distorts the ground and antennas somewhat.

During her more than six year lifetime spanning until March 2010, Spirit discovered compelling evidence that ancient Mars exhibited hydrothermal activity, hot springs and volcanic explosions flowing with water.
“Spirit’s big scientific accomplishments are the silica deposits at Home Plate, the carbonates at Comanche, and all the evidence for hydrothermal systems and explosive volcanism, Rover Principal Investigator Steve Squyres of Cornell University, explained to me in an earlier interview.
“What we’ve learned is that early Mars at Spirit’s site was a hot, violent place, with hot springs, steam vents, and volcanic explosions. It was extraordinarily different from the Mars of today.”
Meanwhile, NASA’s new Curiosity rover just celebrated 500 Sols on Mars and is speeding towards Mount Sharp from inside Gale Crater – which is about the same size as Gusev crater.
Stay tuned here for Ken’s continuing Mars rover, Curiosity, Chang’e-3, SpaceX, Orbital Sciences, LADEE, MAVEN, MOM and more news.

The images were acquired on Spirit’s sols 583 to 586 (Aug. 24 to 27, 2005), shortly after the rover reached the crest of “Husband Hill” inside Mars’ Gusev Crater. The panoramic camera shot 653 separate images in 6 different filters, encompassing the rover’s deck and the full 360 degrees of surface rocks and soils visible to the camera from this position. This was the first time the camera has been used to image the entire rover deck and visible surface from the same position.

Spirit collected data in late 2005 which confirmed that the Comanche outcrop contains magnesium iron carbonate, a mineral indicating the past environment was wet and non-acidic, possibly favorable to life. This view was captured during Sol 689 on Mars (Dec. 11, 2005). The find at Comanche is the first unambiguous evidence from either Spirit or Opportunity for a past Martian environment that may have been more favorable to life than the wet but acidic conditions indicated by the rovers’ earlier finds.

Today, Jan. 3, marks the 10th anniversary since the safe landing of NASA’s renowned Spirit rover on the plains of Mars on Jan. 3, 2004.
Spirit comprises one half of NASA’s now legendary pair of Mars Exploration Rovers (MER). Opportunity, her twin sister landed, on the opposite side of the Red Planet three weeks later – on Jan. 24, 2004. The goal was to “follow the water” as a potential enabler for past Martian microbes if they ever existed.
Together, the long-lived, golf cart sized robots proved that early Mars was warm and wet, billions of years ago – a key finding in the search for habitats conducive to life beyond Earth.
Exactly a decade ago, the famous robot survived the scorching atmospheric heating of the 6 minute plunge through the thin Martian atmosphere, bounced some two dozen times cocooned inside cushioning airbags, and gradually rolled to a stop inside 100 mile wide Gusev Crater. It was known as the “6 minutes of Terror”.
The three petaled landing pad opened and Spirit was dramatically born in a milestone event that will be forever remembered in the annuls of history because of the groundbreaking scientific discoveries that ensued and the unbelievable longevity of the twins.

Before they were launched atop Delta II rockets in the summer of 2003 from Cape Canaveral, the dynamic, solar powered robo duo were expected to last a mere three months – with a ‘warranty’ of 90 Martian days (Sols).
Either dust accumulation on the life giving solar panels, an engineering issue or the extremely harsh Martian environment was expected to somehow terminate them mercilessly.
In reality, both robots enormously exceeded expectations and accumulated a vast bonus time of exploration and discovery in numerous extended mission phases.
‘McMurdo’ Panorama from Spirit’s ‘Winter Haven’
This beautiful scene reveals a tremendous amount of detail in Spirit’s surroundings at a place called “Winter Haven,” where the rover spent many months parked on a north-facing slope in order to keep its solar panels pointed toward the sun for the winter. During this time, it captured several images to create this high resolution panorama. During that time, while the rover spent the daylight hours conducting as much scientific research as possible, science team members assigned informal names to rock outcrops, boulders, and patches of soil commemorating exploration sites in Antarctica and the southernmost islands of South America. Antarctic bases are places where researchers, like the rovers on Mars, hunker down for the winter in subzero temperatures. During the past Martian winter, Spirit endured temperatures lower than minus 100 degrees Celsius (minus 148 degrees Fahrenheit). Credit: NASA/JPL/Cornell
No one foresaw that Martian winds would occasionally clean the solar panels to give them a new lease on life or that the components would miraculously continue functioning.
Spirit endured the utterly extreme Red Planet climate for more than six years until communications ceased in 2010.
Opportunity is still roving Mars today, and doing so in rather good condition!
Altogether, Spirit drove 4.8 miles (7.73 kilometers),that’s about 12 times more than the original goal set for the mission.
She transmitted over 128,000 images.
After landing in the dusty plains, she headed for the nearby Columbia Hills some 2 miles away and ultimately became the first Martian mountaineer, when she scaled Husband Hill and found evidence for the flow of liquid water at the Hillary outcrop.
Spirit acquired this mosaic on Sol 1202 (May 21, 2007), while investigating the area east of the elevated plateau known as “Home Plate” in the “Columbia Hills.” The mosaic shows an area of disturbed soil, nicknamed “Gertrude Weise” by scientists, made by Spirit’s stuck right front wheel. The trench exposed a patch of nearly pure silica, with the composition of opal. It could have come from either a hot-spring environment or an environment called a fumarole, in which acidic, volcanic steam rises through cracks. Either way, its formation involved water, and on Earth, both of these types of settings teem with microbial life. Credit: NASA/JPL-Caltech/Cornell
The rovers were not designed to climb hills. But eventually she scaled 30 degree inclines.
The rover was equipped with a rock grinder named the Rock Abrasion Tool (RAT) built by Honeybee Robotics.
Spirit ground the surfaces off 15 rock targets and scoured 92 targets with a brush to prepare the targets for inspection with spectrometers and a microscopic imager, according to NASA.
Eventually she drove back down the hill and made even greater scientific discoveries in the area known as ‘Home Plate’.
Spirit survived three harsh Martian winters and only succumbed to the Antarctic-like temperatures when she unexpectedly became mired in an unseen sand trap driving beside an ancient volcanic feature named ‘Home Plate’ that prevented the solar arrays from generating life giving power to safeguard critical electronic and computer components.
In 2007, Spirit made one of the key discoveries of the mission at ‘Home Plate’ when her stuck right front wheel churned up a trench of bright Martian soil that exposed a patch of nearly pure silica, which was formed in a watery hot spring or volcanic environment.
Spirit was heading towards another pair of volcanic objects named ‘von Braun’ and ‘Goddard’ and came within just a few hundred feet when she died in the sand trap.

Here’s how the rovers’ principal investigator, Steve Squyres of Cornell University, Ithaca, N.Y., described some of the key findings in a NASA statement, starting with what Spirit found after driving from the crater floor where it landed into the Columbia hills to the east:
“In the Columbia Hills, we discovered compelling evidence of an ancient Mars that was a hot, wet, violent place, with volcanic explosions, hydrothermal activity, steam vents — nothing like Mars today.
“At Opportunity’s landing site, we found evidence of an early Mars that had acidic groundwater that sometimes reached the surface and evaporated away, leaving salts behind. It was an environment with liquid water, but very different from the environment that Spirit told us about.
“When Opportunity got to the rim of Endeavour Crater, we began a whole new mission. We found gypsum veins and a rich concentration of clay minerals. The clay minerals tell us about water chemistry that was neutral, instead of acidic — more favorable for microbial life, if any ever began on Mars.”
“Because of the rovers’ longevity, we essentially got four different landing sites for the price of two.”
Meanwhile, NASA’s new Curiosity rover just celebrated 500 Sols on Mars and is speeding towards Mount Sharp from inside Gale Crater – which is about the same size as Gusev crater.

The popular jazz tune “Stars Fell on Alabama” was inspired in part by the Leonid meteor shower in November of 1833, sometimes referred to as “the night the stars fell.” But the central region of Alabama region has a history of meteorite impacts, including a massive impact over 84 million years ago. The town of Wetumpka, Alabama sits in the middle of an ancient 8-kilometer-wide impact crater that was blasted into the bedrock, creating the unique geology of what is now Elmore County.
To celebrate this “striking” heritage, Wetumpka celebrates every New Year’s Eve with a spectacular recreation of a falling, exploding meteor.
Geologists have pieced together the events from millions years ago, when an asteroid nearly the size of a football stadium crashed into what was at the time a coastal basin covered with a shallow sea. The jumbled and disturbed geology of the area hadn’t made sense to local geologists since they started studying it in the 1800’s, and they had no explanations until mapping in the early 1970’s showed that the rocky layers were pointing away from a central location, which led them to suspect some sort of large impact.
However, this location wasn’t verified as an impact crater until fairly recently, when core samples drilled in 1998 confirmed the impact by detecting the presence of shocked quartz. The Wetumpka Impact Crater was officially recognized in 2002, and is now considered to be the best preserved marine impact crater ever discovered.

And so, in honor of this history, the folks of Wetumpka have been ringing in the new year by having their own ‘meteor’ streak across the sky and drop to the ground, guided by a wire and followed by fireworks. This event has been recognized as one of the top 10 unique New Year’s Celebrations in the U.S. by TripAdvisor.
Three visual athletes based in Arizona took up the challenge on Wednesday evening, with amazing results. Mike Weasner, Rob Sparks and Jim Cadien managed to spot the razor thin crescent Moon just 13 hours and 48 minutes after it passed New phase earlier on January 1st. The sighting was made using binoculars, and they even managed to image the wisp of a crescent hanging against the desert sky.
This is a difficult feat, even under the best of conditions. Weasner and Sparks observed from Mike’s Cassiopeia observatory based just outside of Oracle, Arizona.

Concerning the feat, Weasner wrote on his observing blog:
“At 1800 Mountain Standard Time (MST), Rob reported that he had located the young Moon using his 8×42 binoculars. At 18:02 MST, I picked it up in the 12×70 binoculars. With the New Moon occurring at 11:14 Universal Time (UT), my observation occurred with the Moon only 13 hours and 48 minutes old. A new record for me (and Rob and Jim as well). Our DSLRs were clicking away!”
We can personally attest to just how hard it is to pick out the uber-thin crescent Moon against the twilight sky. Low contrast is your enemy, making it tough to spot and even tougher to photograph. Add to that a changing twilight sky that alters hue from moment to moment.
Though this isn’t a world record, its close to within about two hours. The youngest confirmed Moon spotting using binoculars stands at 11 hours and 40 minutes accomplished by Mohsen G. Mirsaeed in Iran back in September 7th, 2002, and the youngest Moon sighted with the unaided eye goes to Steven James O’Meara in May 1990, who spotted a 15 hour 32 minute old crescent.

And of course, you can see the Moon at the moment of New during a a solar eclipse. Unfortunately, no total solar eclipses occur in 2014, just an usual non-central annular eclipse brushing Australia and Antarctica on April 29th and a deep 81% partial eclipse crossing North America on October 23rd.
Weasner also noted that a bright Venus aided them in their quest. It’s strange to think that Venus, though visually tiny, is actually intrinsically brighter than the limb of the Moon, owing to its higher albedo. In fact, some great pictures have also been pouring in to Universe Today of Venus as it heads towards inferior conjunction this month on January 11th. And don’t forget, that quoted magnitude of the lunar crescent (about magnitude -3.4) was also scattered along the lunar disk which was only 0.4% illuminated, and subject to atmospheric extinction to boot!

And yes, it is possible to catch the Moon photographically during a non-eclipse at the moment of New phase. The Moon can wander up to 5 degrees – about ten times its average apparent diameter as seen from the Earth – above or below the ecliptic and appear a corresponding distance from the limb of the Sun. Unlike many moons in the solar system, Earth’s moon has a fixed inclination to our orbit (as traced out by the ecliptic,) not our rotational axis. Thierry Legault accomplished this challenging photographic feat last year. Of course, this should only be attempted by seasoned astrophotographers, as aiming a camera near the Sun is not advised.

Why attempt to spot the razor thin New Moon? What’s the benefit? Well, several lunar based dating systems, such as the Islamic calendar, rely on the spotting of the new crescent Moon to mark the beginning of a new month. Being strictly lunar-based, the Islamic calendar moves an average of -11 days out of sync each year versus the modern day Gregorian calendar. On some years, there can even be a bit of ambiguity as to exactly when key months such as Ramadan will begin based on when the Moon is first sighted.
Also, such a feat demonstrates what the human eye is capable of when pushed to its physiological limits. In fact, French astrophysicist Andre Danjon theorized that the lunar crescent is formed at about 5 degrees elongation from the Sun, a point beyond which a lunar crescent can be sighted — usually quoted at about 7 degrees elongation from the Sun — and has become known as the Danjon Limit. Danjon also gave his namesake to the characterization of total lunar eclipses by color and hue, known as the Danjon Number. Accounting for the motion of the Moon, this places the theoretical limit that the forming crescent can be sighted with optical assistance at just over 11 hours.
Optimal sighting locations through the end of September 2014. Positions are marked for where the Moon is visible at local sunset and becomes visible with optical assistance around 14 hours after New. Prospects for a “first sighting” get better westward of each location on the dates noted. Note that the March 1st event offers decent prospects for the US northeast and the Canadian Maritimes. Graphic created by author.
And you don’t have to wait until the Moon passes New… a similar attempt can be made in the dawn skies as the waning crescent Moon slides towards the Sun at the end of each lunation.
But perhaps the true reward is simply catching a glimpse of the ethereal for yourself, a delicate and airy Moon clinging briefly on the horizon. Kudos to Mike and Rob on a great catch!

The status quo in space flight operations is no more.
Private American rockets are leading the charge of overdue change into the innovative ‘Commercial Space Race’ by blasting 2014 open with a pair of ‘Big Bang fireworks’ just a day apart on Jan. 6 and Jan. 7.
A dynamic duo of US aerospace firms – SpaceX and Orbital Sciences – are each poised to launch their own recently developed private boosters in the first week of the new year and aiming to dramatically cut costs.
And to top that off, the rockets are thundering aloft from two different spaceports located some 800 miles apart along the US East coast – weather permitting of course given the monster snow storm and frigid arctic air – akin to Mars – bearing down at this very moment on the big populations centers of the Atlantic coast region.
UPDATE ALERT – Antares Launch just postponed to Wed, Jan 8 at 1:32 p.m.due to extremely cold weather forecast. Back up day is Jan. 9
Both companies are revolutionizing access to space for both government entities as well as commercial companies doing lucrative business in space.
The implications of vastly reducing expenses for space travel and space commerce are far reaching and imperative – especially in the face of static and declining budgets mandated by politicians worldwide.
Except for China, which just landed its first rover on the Moon, is investing mightily in space and science and reaping strong economic growth.
Next Generation SpaceX Falcon 9 rocket blasts off with SES-8 communications satellite on Dec. 3, 2013 from Pad 40 at Cape Canaveral, FL. Credit: Ken Kremer/kenkremer.com
SpaceX is first on deck with their next generation Falcon 9 rocket poised to soar on Monday, Jan. 6, with a highly valuable international payload – the Thiacom-6 commercial broadcasting satellite.
Note: This launch has just been postponed from Jan. 3 according to a brief statement I received from the USAF 45th Space Wing. Apparently due to concerns with the rocket – better safe than sorry.
Orbital Sciences follows up quickly on Tuesday, Jan. 7, with their two stage Antares rocket carrying the firm’s own Cygnus cargo vessel on its first operational commercial resupply mission for NASA – that’s bound for the International Space Station (ISS).
The upgraded SpaceX Falcon 9 v1.1 two stage rocket is slated to launch from complex 40 at Cape Canaveral Air Force Station, Florida, likely at dusk.
The original Jan. 3 Falcon 9 evening time launch had been scheduled for 5:50 p.m. Thaicom-6 will be placed into an elliptical supersynchronous transfer orbit.
The commercial space race sometimes makes for strange bedfellows. The Thaicom-6 satellite was built by Orbital Sciences.
This marks only the 2nd launch of the newly upgraded Falcon 9 from Florida. Read my eyewitness reports about the thunderous maiden liftoff barely a month ago on Dec. 3, 2013 with the SES-8 commercial telecom satellite – starting here.
The new Falcon 9 is the key to achieving SpaceX’s future launch manifest of some 50 payloads worth billions of dollars.
The next gen Falcon 9 will also launch the human rated SpaceX Dragon to the ISS. But first the Dragon and Falcon 9 must successfully achieve a pair of abort tests planned for 2014. Read my new article and discussion with SpaceX CEO Elon Musk – here.
The Jan. 7 Antares liftoff is currently scheduled for 1:55 p.m. EST from Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops Island, Virginia.

The Antares launch comes on the heels of the completely successful demonstration flight to the space station by Orbital Sciences in September 2013.
This flight was originally scheduled for mid-December 2013 in prime time but was postponed due to the urgent repairs required to get the ISS cooling system back in full operation.
And although it’s now moved to daylight by reason of orbital mechanics, the liftoff could still easily be visible to millions of residents along a wide swath of the US East Coast spanning from North Carolina to New York City – weather permitting.

I’ll be covering the Antares launch, dubbed Orb-1, from on site at NASA Wallops – watch for my continuing reports.
The Cygnus logistics vessel will carry a total of 2,780 pounds of supplies to the station, including vital science experiments to expand the research capability of the Expedition 38 crew members aboard the orbiting laboratory, crew provisions, spare parts and experiment hardware, says NASA.
Also packed aboard the Antares/Cygnus flight are a batch of student experiments involving life sciences topics ranging from amoeba reproduction to calcium in the bones to salamanders.
“The 23 experiments flying next week [on Antares/Cygnus] are the culmination of 8,700 students engaged in real experiment design, and 1,800 proposals received by student teams,” Dr. Jeff Goldstein told Universe Today. Goldstein is the Center Director for the National Center for Earth and Space Science Education (NCESSE),which is sponsoring and organizing the student experiments.
This rocket volley is but the opening salvo of shots heard reverberating round the world that will surely “rock” the space industry to its core by cutting the steep cost of access to space.
“This is really rocking the industry. Everybody has to look out,” said Martin Halliwell, SES chief technical officer during a recent media briefing with Elon Musk, including Universe Today.
Both the SpaceX Falcon 9/Dragon and Orbital Sciences Antares/Cygnus vehicles were developed from the start with seed money from NASA in a public-private partnership.
The goal was to restore America’s cargo and crew capabilities to low Earth orbit and the ISS that was totally lost following the forced retirement of NASA’s Space Shuttles.
After a slow start, both Orbital Sciences and SpaceX have succeeded in bringing their new rockets and delivery vehicles safely on line.
SpaceX next Dragon cargo launch to the ISS is currently scheduled for Feb. 22, said SpaceX spokeswoman Emily Shanklin to Universe Today.

2014 starts out with sunset view of a new Moon and a fading look at Venus, both captured together in this gorgeous image from astrophotographer Giuseppe Petricca.
“A wonderful sunset conjunction this evening from Central Italy,” Giuseppe wrote via email. “The Moon and Venus were both crescent, in an awesome sight! Some clouds entered the scene, and helped me filter the bright light of the ‘evening star’, revealing the little arch of the planet, from our point of view.” He added that this is “the youngest Moon I’ve ever captured, about 2% lit.”
Below is an image with an inset of Venus enlarged for a better view:

As our writer Bob King noted in his recent article, catch Venus now while you can, as it is slipping away: “As 2013 gives way to the new year, Venus winds up its evening presentation as it prepares to transition to the morning sky. Catch it while you can. Each passing night sees the planet dropping ever closer to the horizon as its apparent distance from the sun shrinks. On January 11 it will pass through inferior conjunction as it glides between Earth and Sun.”
Giuseppe’s images were taken with a simple non-reflex camera on a tripod, Nikon P90, ISO 100, f5.0, 1/2 exposure, which he says demonstrates “that with a little effort, you don’t need an expensive digicam to take this kind of shot.”

This was very likely the last trip around the Sun for the Earth-crossing asteroid 2014 AA, according to calculations by several teams of astronomers and published online earlier today on the IAU’s Minor Planet Center. Discovered just yesterday by the Catalina Sky Survey, the estimated 3-meter-wide Apollo asteroid was supposed to clear Earth today by a razor-thin margin of about 611 km (380 miles)… but it’s now looking like it didn’t quite make it.
The diagram above, via Asteroid Initiatives’ Twitter feed, shows a projected path probability pattern for 2014 AA’s re-entry locations. No eyewitness accounts have yet been reported, and if anyone knows of any surveillance cameras aimed in those directions that might have captured footage of a bolide feel free to share that info below in the comments and/or with @AsteroidEnergy on Twitter.
Other calculations put the entry point anywhere between western Africa and Central America.
According to the MPEC report the asteroid “was unlikely to have survived atmospheric entry intact.”

JPL’s Near-Earth Object program classifies Apollo asteroids as “Earth-crossing NEAs with semi-major axes larger than Earth’s (named after asteroid 1862 Apollo).” And while not an Earth-shattering event (fortunately!) this is just another small reminder of why we need to keep watch on the sometimes-occupied path our planet takes around the Sun!
UPDATE: Based on infrasound analysis by Peter Brown of the University of Western Ontario, 2014 AA likely impacted the atmosphere over the Atlantic around 0300 UTC at 40° west, 12° north — about 1,900 miles east of Caracas, Venezuela. The impact released the equivalent of 500 to 1,000 tons (0.5 – 1 kiloton) of TNT, but far above a remote and uninhabited area. Read more on Sky & Telescope here.

As 2014 opens, most of the half dozen comets traversing the morning and evening sky are faint and require detailed charts and a good-sized telescope to see and appreciate. Except for Comet Lovejoy. This gift to beginner and amateur astronomers alike keeps on giving. But wait, there’s more. Three additional binocular-bright comets will keep us busy starting this spring.

Still glowing around the naked eye limit at magnitude 6, the Lovejoy remains easy to see in binoculars from dark skies as it tracks from southern Hercules into Ophiuchus in the coming weeks.
The best time to view the comet is shortly before the start of dawn when it sails highest in the eastern sky at an altitude of around 30 degrees or “three fists” up from the horizon. By January’s end, the comet will still be 25 degrees high in a dark sky. My last encounter with Lovejoy was a week ago when 10×50 binoculars revealed a bright coma and 1.5 degree long tail to the northwest. Through the telescope the stark contrast between bright, compact nucleus and gauzy coma struck me as one of the most beautiful sights I’d seen all month.

Looking ahead to 2014 there are at present three comets beside Lovejoy that are expected to wax bright enough to see in binoculars and possibly with the naked eye: C/2012 K1 PanSTARRS, C/2013 V5 Oukaimeden and C/2013 A1 Siding Spring The first lurks in Hercules but come early April should bulk up to magnitude 9.5, bright enough to track in a small telescope for northern hemisphere observers. Watch K1 PANSTARRS amble from Bootes across the Big Dipper and down through Leo from mid-spring through late June hitting magnitude 7.5 before disappearing in the summer twilight glow. K1 will be your go-to comet during convenient viewing hours.
Come early September after K1 PANSTARRS leaves the sun’s ken, it reappears in the morning sky, traveling westward from Hydra into Puppis. Southern hemisphere observers are now favored, but northerners won’t suffer too badly. The comet is expected to crest to magnitude 5.5 in mid-October just before it dips too far south for easy viewing at mid-northern latitudes.
Comet Oukaimeden may glow around 8th magnitude in late August 2014 when it rises with the winter stars before dawn. Stellarium.
Comet C/2013 V5 (Oukaimeden), discovered November 15 at Oukaimeden Observatory in Marrekesh, Morocco. Preliminary estimates place the comet at around magnitude 5.5 in mid-September. It should reach binocular visibility in late August in Monoceros the Unicorn east of Orion in the pre-dawn sky before disappearing in the twilight glow for mid-northern latitude observers. Southern hemisphere skywatchers will see the comet at its best and brightest before dawn in early September and at dusk later that month.

2014’s most anticipated comet has to be C/2013 A1 Siding Spring, expected to reach magnitude 7.5 and become binocular-worthy for southern hemisphere skywatchers as it traverses the southern circumpolar constellations this September. Northerners will have to wait until early October for the comet to climb into the evening sky by way of Scorpius and Sagittarius. Watch for an 8th magnitude hazy glow in the southwestern sky at that time.
As October ticks by, A1 Siding Spring creeps closer and closer to Mars until it overlaps the planet on the 19th. Normally, a comet will only appear to pass in front of stars and deep sky objects because it’s in the same line of sight. Not this time. Siding Spring may actually “touch” Mars for real.
Comet C/2013 A1 Siding Spring will overlap Mars on October 19, 2014. Assuming magnitude 8 at the time, the comet should look like a hazy glow around the planet through binoculars and telescopes. Stellarium
On October 19 the comet will pass so close to the planet that its outer coma or atmosphere may envelop Mars and spark a meteor shower. The sight of a bright planet smack in the middle of a comet’s head should be something quite wonderful to see through a telescope.
While the list of predicted comets is skimpy and arguably not bright in the sense of headliners like Hale-Bopp in 1997 or even L4 PANSTARRS from last spring, all should be visible in binoculars from a dark sky site.
Every year new comets are discovered, some of which can swiftly brighten and put on a great show like Comet Lovejoy (discovered Sept. 7) did last fall and continues to do. In 2013, 64 new comets were found, 14 of them by amateur astronomers. Comets with the potential to make us ooh and aah are out there – we just have to find them.
