Synthesized images as they would be observed at the limb by AIA/SDO in the 304 Å and 171 Å bands dominated by the He ii line and the Fe ix/x lines, respectively. These snapshots shows the ejection at t = 47 min, i.e., at the same time as the middle row of Fig. 1 and as Fig. A.1. The original synthesized images are downgraded to match the spatial resolution of AIA/SDO. The intensity is given in expected AIA counts per pixel and second.
