I haven't done photometry to the frames as I am no expert and others are
producing much better data than I could do.
I did process two identical 15 frame stacks using the same baseline and
calibration frames. The inner coma (a few central pixels) clearly gets
much brighter. The peak is about ~6700 before impact (on a sky
background of 500) while a few minutes after impact it is ~10600, not
quite a factor of two, but close.
Less than a magnitude but easily enough that skilled visual observers
would have been able to see the difference.
