Snapshots of the multi-thermal loop observed with SDO/AIA at 171 Å (left) and STEREO/EUVI-A at 195 Å (right). The circles mark the loop footpoints, whilst the dotted region encloses the loop in both views. The red arrow in the left panels mark the position of the loop during its evolution and the green one that of a transient loop in AIA. The movie showing the temporal evolution as seen in the 171 Å channel of AIA is available in the online edition.
