Overview of the B-class flares and eruption of December 9, 2020, as observed by SDO in three AIA filters at 94 Å, 171 Å, and 304 Å. Note that the Fe XVIII contribution has been separated from the 94 Å filtergrams (see Appendix B). The HMI magnetogram of a portion of the decaying AR is shown in panel (a), and is saturated to ±300 G. One example of an interaction between the filament with a bent arcade (loops) is shown in panels (a4)–(b4) with the evolution of the hot flux indicated by white arrows in panel (a4). An online animation is attached to this figure (Movie_overview_aia.mpg).
