Flare as seen from the Earth and EUV/STEREO points of view. The first two columns show the NRH radio contours at different frequencies (level of 80% maximum value in each frequency) and STIX X-ray contours overlaid on the running time difference images of AIA/SDO 171 and 193 Å at the onset time of ‘M’ (T₁) and at the end of moving type IV burst at high frequencies (T₂). The contours in different colors represent different NRH frequencies: 228 MHz (orange), 271 MHz (yellow), 299 MHz (olive), 327 MHz (cyan), 408 MHz (sky-blue), and 432 MHz (blue). STIX X-ray contours in blue represent 6–10 keV and cyan is 10–18 keV. (a and b) The times of the AIA/SDO 171 Å and 193 Å images are resp. 14:15:21 UT, and 14:15:16 UT. (d and e) Times of the AIA/SDO 171 Å and 193 Å images are resp. 14:20:21 UT, and 14:20:28 UT. The third column shows EUVI/STEREO-A 195 Å images. The times of each row are similar: more precisely the time of the EUVI/STEREO-A image in (c) is 14:15 UT and in (f) 14:20 UT. The red crosses shown in every image denote the same point on the Sun.
