Upper left-hand panel: temporal average of AIA 304 Å intensity, with HMI continuum intensity contours from Fig. 1 overlayed. The green solid and dashed lines indicate a path of inflows and the area of integration used for the time-distance plot in the right panel. Lower left panels: temporal average images of HMI continuum intensity and three AIA channels. The red marks indicate the satellite region and Point C as in Fig. 1. Central panels: temporal evolution of the O iv and Si iv lines averaged over 13 pixels in the northern satellite region centered on Point C. The region of the satellite in Si iv, indicated by the bar on top, has been contrast-enhanced to better show the weak connection to the main component’s shock maneuvres. Right panel: relative AIA 304 Å intensity fluctuations, integrated across the path identified by the green lines in the context image in the upper left. The colour table maps variations from −30% to +30%. Coronal rain is visible with plane-of-sky velocities comparable to the downflow velocity of the satellite (90 km s-1, indicated by the white line). However, these inflows do not seem to extend to the position of the satellite feature in the umbra but appear to end at the lightbridge, as identified by the vertical, blue lines in the time-distance plot and the corresponding marks on the path in the HMI continuum context image.
