Magnetic Solar FIlament

ERUPTING MAGNETIC FILAMENT: A filament of magnetism connecting sunspots AR1538 and AR1540 rose up and erupted on August 4th. Look for the extreme UV glow of hot plasma in this movie recorded by NASA’s Solar Dynamics Observatory:

As the filament ripped through the sun’s atmosphere, it propelled a massive CME into space: movie. The expanding cloud does not appear to be on a collision course with Earth, although a glancing blow might be possible 2 to 3 days hence.
