The sun will disappear completely behind the shadow of the moon in Southeast Asia Tuesday in a total solar eclipse.
If you can't make it there in person, you can watch live via Slooh or NASA, in collaboration with Exploratorium and the National Science Foundation — and there will be plenty of opportunities to ask questions, learn about the eclipse and share photos as the moment arrives.
The online Slooh Community Observatory will host a live webcast between 6 and 9 p.m. EST to watch the eclipse from Indonesia and "several other locations" along the eclipse path, which can be joined at Slooh.com; the period of totality (total eclipse) will begin at 7:37 p.m. EST. The webcast will also visible at Space.com, courtesy of Slooh.
Throughout the days before Slooh's broadcast, astronomer Paul Cox will share details of his journey in Indonesia. The broadcast will be hosted by Cox and will include commentators such as solar expert Lucie Green and Slooh astronomer Bob Berman. Twitter viewers can ask questions using the hashtag #SloohEclipse.
Before the eclipse happens, Slooh is asking fans to show how they safely plan to view the eclipse. Social media users can use the hashtag #ShadeUp on Instagram, Twitter and Facebook. Slooh is also asking its followers to post pictures of the eclipse on Twitter (tagging @Slooh) or Facebook.
NASA Television will start coverage of the eclipse at 8 p.m. EST on March 8, including a live view from the Federated States of Micronesia in collaboration with Exploratorium and the National Science Foundation. The broadcast will run at http://www.nasa.gov/ntv.
