Sunspot 1087

Magnetic fields overlying sunspot 1087 became unstable and erupted. The explosion emitted a bright flash of UV light (a C3-class solar flare) and hurled a massive plume of hot plasma away from the sun.

Below is the picture taken this morning from our new Alien House Observatory. Make sure to watch a video from NASA's Solar Dynamics Observatory (SDO) showing a sequence of B and C class flares taken over several hours.
