Caption: Although so-called "post-CME loops" are quite common, they sometimes come in odd shapes that are revealed when they are seen close to the limb - like the kinked one shown in the center of the EIT 195 Å image above. It is part of what is called a "post-CME arcade", with a large number of individual loops that brighten after the CME has taken off.
The EIT movie sequences also show the Coronal Mass Ejection itself as a very substantial dimming from one frame to another (the material is gone in the image at 19:28 UT). It can be followed through the LASCO C2 and C3 coronagraph images, which also features several other CME events.
