MAGNIFICENT ERUPTION: On August 31st, a magnetic filament on the sun erupted in spectacular fashion, producing a long-duration solar flare, a coronal mass ejection (CME) and one of the most beautiful movies of an explosion ever recorded by NASA's Solar Dynamics Observatory. The CME propelled by the blast might deliver a glancing blow to Earth's magnetic field in the days ahead. Check http://spaceweather.com for movies, forecasts and updates.
