The period of total eclipse, called totality, will occur from 8:38 to 8:42 p.m.
Twitter, Google+, Facebook, and Instagram users will be able to join the conversation and ask questions using the hashtag #eclipse2016. The NASA Twitter account for the eclipse is @NASASunEarth. The public will be able to tag and share their images of the solar eclipse on the NASA Flickr group at: flickr.com/groups/eclipse2016/.
The total eclipse will be visible in parts of South East Asia and a partial eclipse will be visible in parts of Alaska, Hawaii, Guam and America Samoa.
An eclipse occurs when the moon passes directly between Earth and the sun.
When the moon's shadow falls on Earth, observers within that shadow see the moon block a portion of the sun's light.
