Collapsed Filament


A dark, solar filament above the Sun's surface became unstable and erupted, which generated a cascade of magnetic arches (Dec. 16-17, 2015). A small eruption to the upper right likely caused the filament's collapse. The action, observed in extreme ultraviolet light, covered about a 28-hour period. The magnetic arches are charged particles spinning along magnetic field lines that are reorganizing themselves after the event. Credit: Solar Dynamics Observatory, NASA.
