A Huge Solar Filament Erupts
Explanation: Click the arrow and watch an unusually long filament explode out from the Sun. The
filament had been seen hovering over the
Sun's surface for over a week before it erupted earlier this month. The
image sequence was taken by the Earth-orbiting
Solar Dynamics Observatory (SDO) in a color of
ultraviolet light specifically emitted by helium.
The explosion created
Coronal Mass Ejections which dispersed high energy plasma into the Solar System. This
plasma cloud, though, missed the Earth and so did not cause auroras. The
above eruption and an
unusually expansive eruption that occurred in August are showing how widely separated areas of the
Sun can sometimes act in unison.
Explosions like this will likely become more common over the next few years as our Sun moves toward
Solar Maximum activity.
