Red Hot Ballet
November 2, 2012
This minor eruption rises and falls with the grace and polished movement of a ballet dancer (Oct. 4, 2012). The close-up video at just about full resolution captures the event in extreme ultraviolet light with this 2.5-hour observation. Most of the particles do not have enough momentum to break away into space and are pulled down again into the Sun. The movie was made using an image every 15 seconds, played back at 15 frames per second.
