Standing in the Shadow: Amazing Images of Today’s Total Solar Eclipse
The Moon’s shadow kissed the Earth earlier today, providing a fine show from southeast Asia, to the southern shores of Alaska. We wrote about the only total solar eclipse for 2016 yesterday. This is it, the last total solar eclipse prior to the return of totality for the contiguous United States on August 21st, 2017.
Cloud cover over the region was a toss up, with clear skies for some, and cloudy skies for others. Those towards the western end of the track where the eclipsed rising Sun sat low on the horizon seemed to have fared worst.
Update: Sometimes, the camera sees what the eye misses. The Malaysian team did indeed manage to nab a fine display of Bailey’s Beads in the moments leading up to totality through a thin gap in the clouds:
Skies dawned clear to the east over the Indonesian islands on the morning of the eclipse, and the joint NASA/Exploratorium webcast from the remote atoll of Woleai in Micronesia was a success.
Observing from a helipad Balikpanpan, Indonesia, veteran eclipse chaser Patrick Poitevin said: “What an eclipse! Vertically clear sky throughout the entire eclipse from our ‘private’ helipad in Balikpapan. Only slight haze now and then. Asymmetric corona, with bright and prominent snow white streamer. Venus, Mercury easily visible long before, and shadow bands post totality. Fabulous! All so pretty!!! Marked the second Saros 130 for Jo and the 3rd for me.”
Indeed, catching a ‘triple saros’ known as an exeligmos is a noteworthy lifetime accomplishment.
Many witnessed the eclipse via Slooh’s live webcast from the path of totality, which is now archived in its entirety on YouTube.
As of writing this, no views from space have surfaced, though we suspect this will change as the day goes on. Word is that the Alaskan Airlines flight that modified their flight plan to catch the eclipse was successful as well. Check back, as we’ll be dropping in more images as they trickle in from the field throughout the day.
Update: Scratch that… Japan’s Himawari-8 weather satellite did indeed nab views of the umbra of the Moon as it raced across the Pacific:
Though the eclipse was almost entirely over water after the umbra departed SE Asia, regions around the path were treated to a fine partial eclipse, including residents of Hawaii:

Chasing the Shadow: Our Guide to the March 9th Total Solar Eclipse
Ready for the ultimate in astronomical events? On the morning of Wednesday, March 9th, the Moon eclipses the Sun for viewers across southeast Asia.
Many intrepid umbraphiles are already in position for the spectacle. The event is the only total solar eclipse of 2016, and the penultimate total solar eclipse prior the ‘Big One’ crossing the continental United States on August 21st, 2017.
Tales of the Saros
This particular eclipse is member 52 of 73 eclipses in saros cycle 130, which runs from 1096 AD to 2394. If you saw the total solar eclipse which crossed South America on February 26th, 1998, then you caught the last solar eclipse from the same cycle.
Weather prospects are dicey along the eclipse track, as March is typically the middle of monsoon season for southeast Asia. Most eclipse chasers have headed to the islands of Indonesia or cruises based nearby to witness the event. The point of greatest eclipse lies off of the southeastern coast of the Philippine Islands in the South China Sea, with a duration of 4 minutes and 10 seconds. Most observers, however, will experience a substantially shorter period of totality. For example, totality lasts only 2 minutes and 35 seconds over island of Ternate, where many eclipse chasers have gathered. The Sun will be 48 degrees above the horizon from the island during totality.
A great place to check cloud cover and weather prospects along the eclipse track is the Eclipsophile website.
The umbra of the Earth’s Moon will sweep across Sumatra at sunrise and across the island of Borneo, to landfall one last time for Indonesia over the island of North Maluku before sweeping across the central Pacific. This eclipse is unusual in that it makes landfall over a very few countries: the island nation of Indonesia, and just a few scattered atolls in Palau and Micronesia.
Partial phases of the eclipse are also visible from India at sunrise, across northeast Asia along the northernmost track, to central Australia in the south, and finally, to southern Alaskan coast at sunset. Honolulu Hawaii sees a 65% partial solar eclipse in the late afternoon on March 8th.
Expect great views, both from Earth and from space. We typically get images from solar observing spacecraft, to include the joint NASA/JAXA Hinode mission, and the European Space Agency’s PROBA-2 spacecraft. Both are in low-Earth orbit, and see a given eclipse as a swift, fleeting event. Other solar observatories—such as the Solar Heliospheric Observatory and the Solar Dynamics Observatory—occupy a different vantage point in space, and miss the eclipse.
As of this writing, we know of several folks that have made the journey to stand in the path of totality, to include Sharin Ahmad (@Shagazer), Michael Zeiler (@GreatAmericanEclipse) and Justin Ng.
Good luck and clear skies to all observers out there, awaiting darkness in the path of totality.
Live in the wrong hemisphere? There are several live webcasts planned from the eclipse zone:
NASA and the National Science Foundation are working with a team from San Francisco’s Exploratorium to bring a live webcast of the eclipse from the remote atoll island of Woleai, Micronesia. The feed starts at 7:00 EST/0:00 Universal Time (UT) and runs for just over three hours. You can follow the exploits of the team leading up to show time here.
The venerable Slooh will also feature a webcast of the eclipse with astronomer Paul Cox from Indonesia running for three hours starting at 6:00 PM EST/23:00 UT.
A view of the partial phases of the eclipse from the Hong Kong science center also starts at 5:30 PM EST/22:30 UT:
Don’t forget: though the eclipse occurs on the morning of March 9th local time in southeast Asia, the path crosses the International Dateline, and the webcasts kick off on the evening of Tuesday March 8th for North America.
And hey, Alaska Airlines flight 870 from Anchorage to Honolulu will divert from its flight plan slightly… just to briefly intercept the Moon’s shadow (its already a fully booked flight!)
From there, 2016 features only two faint penumbral lunar eclipses on March 23rd and September 16th, and an annular solar eclipse crossing central Africa on September 1st.
We’ll be doing a post-eclipse round up, with tales from totality and the pics to prove it… stay tuned!
Got eclipse pictures to share? Send ’em to Universe Today… we just might feature them in our round up!

The Future of Gravitational Wave Astronomy: Pulsar Webs, Space Interferometers and Everything
It’s the hot new field in modern astronomy. The recent announcement of the direct detection of gravitational waves by the Laser Interferometer Gravitational-wave Observatory (LIGO) ushers in a new era of observational astronomy that is completely off the electromagnetic spectrum. This detection occurred on September 14th, 2015 and later earned itself the name GW150914. This occurred shortly after Advanced LIGO turned on in early September, a great sign concerning the veracity of the equipment.

Stunning Images of the February Dawn Planetary Line-up from Around the World
Have you seen them? There’s been a quintet of good reasons to awaken early this past week, as the February dawn sky hosts all five classical planets, very nearly in order: Mercury, Venus, Mars, Saturn and Jupiter. For a few days, the waning crescent Moon even joined the show on the weeks leading up to New on February 8th. Fleeting Mercury breaks the streak later this week, exiting the dawn sky as it heads towards superior conjunction on the far side of the Sun on March 23rd.
