Details:
Sunspots 3335 & 3336 looked great today. I was able to see a flare rapidly develop from nothing to maximum in about 45 seconds. I thought it was an M flare, but it was just C-4. So, I attached the image of this C-4 flare along with a similar image from just 2 minutes earlier showing no flare. 127mm f/9.4 refractor, Quark/Lunt double-stack filter, ASI174mm camera.
