M Class Flare Subsiding In CaK 18th April

When todays M class flare erupted, the seeing conditions in the early afternoon were absolutely awful.  I decided to stop using the 100mm scope and reverted back to the 40mm scope at f20 with the homebrew CaK filter.  This animation represents a period of about 10 minutes after the flare had peaked and was dying back.
