This morning, on 23rd of July, at 02:15, a solar eruption could be witnessed, expanding from the West limb. This eruption likely originated from AR11520 which disappeared around the west limb a few days ago.

A combined movie of the eruption (SWAP 174 (yellow) and AIA 304 (orange)) can be found on the site below: http://proba2.oma.be/swap/data/mpg/movies/campaign_movies/2012_07_23_01_...

Note how the SWAP images allow to follow the eruption further away than the SDO FOV.
