Eruption seen coming from the back of the Sun

YouTube and Helioviewer user goggog67 spotted this event that clearly happened on the other side of the Sun.

The material travels in to the field of view from its launch location, which can be seen in STEREO-B EUVI images. If you go to STEREO latest image selector and select ‘Behind EUVI 195′, pick a resolution of 512 x 512, type in a start and end date of 20120202, and select ‘Slideshow’, you get an animation of the event as seen from STEREO-B. There is a filament eruption on the upper left of the disk (it is hard to spot) which is the same material seen in the AIA 304 movie above:

and a flare in more or less the same area of the Sun – look for the very bright patch at the limb of the Sun at the upper left of the disk.

Thanks to goggog67 for spotting this event and sharing it with us!
