Oscillations captured in smaller loop. (a) AIA 171 x − t map of Slit 8 for the time before, during, and after coronal rain. The blue vertical lines indicate the time interval when coronal rain was present in the SJI 2796 passband. The x − t maps for AIA channels are produced after motion magnification. These x − t maps are inverted in intensity. (b) The x − t map of Slit 8 in SJI 2796. The increase in amplitude is clearly visible, and the oscillation is fitted with the red curve.
