Time evolution (9:32−9:35 UT) of expanding loops observed by SDO/AIA in channels 131 Å (left column), 94 Å (middle column), and 193 Å (right column). The location of the radio source at 5.7 GHz is indicated by a white blob at 9:34 UT (third row). An example of the slit position passing the radio source is shown by an orange vertical solid line in the left column (131 Å) for the 9:34:57 UT panel.
