On Oct 26, 2021, active region AR2891 was still hiding behind the northeastern limb of the Sun, while releasing eight solar flares on that day alone. At around 03:00 UT, the active region released a M1-class flare. I was able to capture an image of the region just before it erupted. I was planning for a timelapse of the region as I noticed that it was actively changing, but unfortunately the clouds rolled in just as I started recording, and therefore missed the whole eruption.
