A sunspot located just out of sight over the sun's eastern limb has unleashed two strong C-class solar flares in the past 24 hours. The sun's rotation should bring this active region into view later today or tomorrow allowing us to evaluate its potential for more explosions. If you have a solar telescope, monitor the limb.

UPDATE: NASA's STEREO-A spacecraft has spotted a bright CME emerging from behind the eastern limb: movie.
