Timeline of EUV 304 Å observations for the AR nest from February to July 2022 (greyscale). From April onwards, the sequence of full-disk images alternates between AIA and EUI (on the far side of the Sun) with roughly two weeks between each image. Each image is centred on 90° Carrington longitude with the AR nest highlighted using a filled blue contour. When visible from Earth, the NOAA AR numbers for this region are annotated in red. The latitude of Solar Orbiter varied by a few degrees in this sequence, which changes the apparent latitude of the AR nest.
