I have similar experiences and been given similar input on the smaller flashes as read above.

Has anyone else seen really large ones in the sky? To compare size, if a star is the size of a pen point, for example, these flashes were at least the size of a quarter, just for reference. At first they were pale orange, then the last couple were white. I probably saw 5-6 over 1-2 months & none since. Anyone?

They were during different types of weather, different times of night, significantly different latitudes, even, I really don't think they were anything to do with planes, weather, or anything like that (I did try researching possibilities, nothing I found fit).
