I may have observed similar tertiary flashes.  However, I was not
expecting them and they were of a nature that I did not consider
them positive events.  But this was with an 8" scope with a
coresponding brighter limiting magnitude.

It is interesting that you observed bright flashes almost an hour
after I finished observing due to clouds.
