The sun will disappear completely behind the shadow of the moon in Southeast Asia tomorrow (March 8) 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 (2300 and 0200 GMT) 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 (0037 GMT). 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 (2500 GMT) 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.
As the broadcast takes place, users of Twitter, Google+ and Facebook can ask questions using the hashtag #eclipse2016. There is also an official Twitter account for the eclipse (@NASASunEarth) and Flickr group, available at https://www.flickr.com/groups/eclipse2016/.
Before the eclipse, at 2 p.m. Monday, solar scientists at NASA's Marshall Space Flight Center in Alabama will host a Facebook Q&A at https://www.facebook.com/nasamarshallcenter.
On Tuesday at 1 p.m., solar scientists at the NASA Goddard Space Flight Center will participate in an "Ask Me Anything" session on Reddit. The link will be made available on NASA Goddard's Twitter feed, @NASAGoddard.
