Active area near the eastern limb of the Sun in the impulsive phase of the 3 November 2010 eruptive flare. AIA 211 Å a) and 131 Å b) base-difference images are overlaid by the RHESSI 6−12 keV (12:13:54−12:14:14 UT; light green) and 25−50 keV (12:13:54–12:14:14 UT; red) contours (20%, 40%, 60%, 80% of the peak flux), indicating locations of the flare soft and hard X-ray sources, respectively. AIA 211 Å base image was made at ≈12:00:02 UT and 131 Å base image – at ≈12:00:11 UT. Yellow ellipses are the NRH 445 MHz contours (70%, 80%, and 90% of the peak flux), which indicate the location of the decimetric radio emission source at the same moment. The thick dashed yellow straight line indicates a projection of the radius-vector passing through the centroid of the flare soft X-ray source onto the image plane.
