Comments: Good seeing but pretty windy again, and frustrating patches of cloud. Not much that's clear on the disk and not perfectly sure if that is due to few bright features or imperfect conditions. There's perhaps a hint of an equatorial spot near lon 025 in the final frame - lower altitude but lighter winds during the final capture.
