AIA view of propagating campfires. The set of five panels at the top presents AIA snapshots of each of our six events. The curved boxes shown in each of these panels mark the locations of the artificial slits we used to derive the temporal evolution in the X-T maps. These X-T maps are shown in the bottom set of panels. Because we were unable to identify event 1 in AIA, we left the corresponding X-T map blank. An animated version of this figure is available online.
