Overview of our observations. Panel a shows a context image from AIA 171 Å, where the red box outlines the SPICE field of view, which is displayed in panel c (C III 977 Å intensity map). The corresponding SDO field of view is outlined with the yellow box and is shown in panels b (HMI line-of-sight magnetogram) and d (AIA 171 Å). The boxes in panels b–d (side length of ≈24 Mm) highlight the 14 bright points we analyzed, which exhibited predominantly flux emergence (blue), flux cancellation (violet), or random motion of the footpoints (green; Sect. 3.2.3). The images in panels a, c, and d are in logarithmic scaling. Those in panels b and d are averaged during the SPICE raster, and their evolution is available in an online movie that spans eight hours centered around the SPICE raster (Sect. 2).
