FILAMENT BREAKAWAY




A dark, elongated filament rose up and broke to the lower left and out from the sun (Apr.9-10, 2017). Filaments are cooler clouds of plasma tethered above the sun's surface by magnetic forces. They are notoriously unstable and tend not to last more than a few days before they collapse into the sun or break away into space. The video, taken in extreme ultraviolet light, covers about nine hours of activity.
