Graceful Twister
June 19, 2012
A stalk-like prominence rose up above the Sun , then split into roughly four strands, that twisted themselves into a knot and dispersed over a two-hour period (July 12, 2011). As the close-up shows (in two wavelengths of extreme ultraviolet light), the effect is one of airy gracefulness. This clip also underscores the value from SDO of being able to view motion with an image taken every 10 seconds.
