Solar Flares Contiune Toward Maximum

This composite movie shows hot solar plasma in red (1.5 million Kelvin, observed in Fe XII 19.3 nm) and green (~1 million Kelvin, Fe IX 17.1 nm) and "cool" solar plasma (60,000-80,000 K, He II 30.4 nm) in blue, all observed with the AIA instrument on SDO on Feb 24, 2010. The real time step between frames is 36 sec, and the movie plays at 25 frames/sec. The duration is 4 1/2 hours, from 06:00 UT - 10:30 UT.
