From footage taken March 16, 2017, 10:07am, NE Ohio. I've been noticing Sun flashes and pulses so decided to check frame by frame, 60 frames per 1 second, to see what my eye misses at regular speed. There is sooo much that pops up, phases in and out, sprinkles down, and flies around. I have no idea what they are, but it's intriguing to see. Nikon P900.
