Evolution of AR 13169 (top left in the first raster) from December 20–22, 2022. Left: SPICE Ne VIII 770 Å rasters overlaid on SDO/AIA 171 Å. Right: Corresponding SDO/HMI magnetograms with C III 977 Å rasters. On the magnetograms, green/(yellow) areas represent positive/(negative) polarity. Note: The dark horizontal lines (“dumbbells”) are square alignment apertures, located at each end of the slits.
