Surge Proms In CaK - 14th April

I was looking again at the data I got from the 14th april, and initially thought all of my CaK shots were a write off, however, spotted I had 6 consecutive frames of ar12320 as it was going over the western limb with this little dynamic surge prom that took place over a couple of minutes.  Taken with the 100mm Tal at 2250mm focal length with the homebrew CaK filter.
