Close-up of the footpoint of the loop bundle where coronal rain is seen on March 30. The FOV corresponds to the white rectangle shown in Fig. 1 (left), rotated by 90° so that the loop is orientated with the height of the page. The vertically oriented and labelled red curves denote several rain clump trajectories. The black arrows point to some of the clumps. The image corresponds to the average over three consecutive frames. The cyan rectangle in the figure corresponds to the FOV shown in Fig. 7. Path 11 is a transverse cut across the loop bundle. The online animation runs from UT 00:23 to UT 00:37 and shows several coronal rain clumps in absorption that fall towards the chromosphere (dark structure at the bottom). The EUV varies strongly in this event. The images from which the movie is composed are processed with the wavelet-optimised whitening enhancement technique of Auchère et al. (2023). The movie first runs without and then with the rain paths overlaid.
