AR3500 before and after major eruption

About this image

AR3500 underwent a major eruption (classed at an M9.8) at 1950 UT on 28-11-23. I had managed to get a few H-alpha solar images on the 28th and 29th, and so it is possible to compare views of AR3500 from before and after the eruption event. On the 28th AR3500 did seem to be very busy and changing rapidly with filaments/plasma clouds rising out of it, but I did not have a continuous view so could not follow the action. But it all really kicked off later.
