This video by NASA's Solar Dynamics Observatory captures a dramatic filament eruption on Aug. 31. Shown in the video in extreme ultraviolet light, the filament collapsed and exploded in spectacular fashion. The segment shown in red covers nearly 3 hours.

The NOAA spaceweather prediction center estimates the resulting cloud of radiation will reach Earth on Sep. 3, but will only create a minor to moderate geomagnetic storm.
