The first portion began at 10:58 p.m. and fully eclipsed at 12:06 a.m. Tuesday. The eclipse was visible from start to finish in North America since the Earth's western hemisphere was facing the moon during the eclipse. It was also visible from South America.
A rare "blood moon," where the moon turns a reddish-orange color, appeared. At the eclipse's peak, the moon entered the Earth's full shadow. The Earth's atmosphere then scattered the sun's red visible light. As a result, the red light reflected off the moon, casting a reddish-orange color over it.
All vehicle access to Griffith Park was closed as crowds gathered at the Griffith Park Observatory to view the blood moon. Parking lots and spaces at the observatory quickly reached capacity, causing heavy traffic.
A public talk was also given at 8 p.m. in the Leonard Nimoy Event Horizon theater.
NASA astronomer Mitzi Adamas and astrophysicist Alphonse Sterling answered questions in a live web chat on www.nasa.gov, beginning at 10 p.m. Monday. The web chat continued through the end of the eclipse, approximately 2 a.m. Tuesday.
NASA urged people to include the hashtag #eclipse when tweeting their thoughts or photos of the phenomenon.
The next full lunar eclipse will not be visible in its entirety until 2019.
