Coronal mass ejection eruption and radio emission from the STEREO perspectives. a–d: intensity and e–h running-difference images taken by STEREO/SECCHI/EUVI-A and -B at the 195 Å (left panels) and 304 Å (right panels) channels around the time of the CME eruption. The radio centroids (together with a ±0.3 R_⊙ error shown for one example centroid) have been projected onto the STEREO-A (e) and -B (f) views. The colour-bar for the radio centroids is the same as in Fig. 3a. Movie 3 is available online.
