Space.com’s 2021 Full Moon Calendar: “This month’s full moon occurs on Thursday, Jan. 28 at 2:16 p.m. EDT (19:16 UTC), but the moon will appear full the night before and after its peak to the casual stargazer. January’s full moon is known as the Wolf Moon, though it has many other nicknames by different cultures.”

Just after 5 p.m. today, now a little before dark, I needed to go out to move groceries from one of our cars into the house. Though not subzero, the post-snow freeze felt pretty cold, maybe because I’d been inside all day.

Sure enough, the moon looked full, not far above the horizon to the east. As I stood outside my garage, I noticed a distant airplane flying (apparently) near the visible full moon. Then I saw it transit the full moon for a split second. Though looking small as a gnat, the outline of the plane was clear, backed by the pale moonlight.

I don’t remember that I’ve ever seen that before. Now I have. Right place, right time.
