Last Gasp of AR13110

In October 2022, the solar acitivity was elevated for the first 6 days, as seen in this GOES/XRS plot. This high activity was mainly brought by AR13110, which produced 7 M-class and one X-class flares during its disk passage.

Unfortunately, XRT was observing another active region (AR13112) located close to the East limb until 10/4 and thus AR13110 and its most significant activities were outside of XRT's field of view.

On 10/4, XRT switched the target region to AR11310 and barely captured an M1.6 flare and the following several C-class events, as demonstrated in the above movie. It's the last huff-and-puff from this region before sinking behind the limb.
