A look at yesterday's M1.3-class solar flare. A new active region rotated right into view and produced some C class and a M1.3 class solar flare.
Right ahead of this region is a beautiful filament.
Long filaments like this one have been known to collapse with explosive results when they hit the stellar surface below.
Filaments are elongated clouds of cooler gases suspended above the Sun by magnetic forces. They are rather unstable and often break away from the Sun.
