Launch of the filament at low cadence (36 seconds) as visible in the 304 Angstrom filter on SDO/AIA.
A large filament of plasma erupted from the Sun in late August 2012. It was a structure that had 'hovered' over the solar surface for some time before finally being launched.
Here are two views of the event - a fast version, illustrating more of the before and after configuration, sampled every 15 minutes; and a slow version, focused around the details of the actual eruption.
