Good shots! Ellerman bombs tend to be visible off band in Ha, your data is definitely on band, I would say just a very small flare.

Definitely not an Ellerman, Ellerman bombs are bright points outside the sunspot area and penumbral grains are bright points on the edge between the penumbral filaments and the umbra, so it could be a penumbral grain or a sub flare as Mark said. Difficult to see (can't enlarge it enough) to see where the penumbra ends at that point. Is the time in UT?

Mark and Montana, the time is actually UT +2. I should correct this to UT.

I wish I had slightly better resolution, but at this stage its all my 71mm scope can do (but very pleased, I think the little guy is a real worker).

The images are all slightly off band as I was playing with the dial on the Quark. How far does one need to be off band approximately?

Im guessing then that was a very quick flare, because it came and had gone in a few minutes.

Most often EB's are seen in the wings but there are events of really bright ones being seen at centre-line. The fact it is within the sunspot area would strongly suggest a flare in this case. An exciting catch and great pics of the event too :)
