Fingernail Moon In Clearwater, FL

The fingernail moon 🌘.

But what is it? And why? I mean, how?

Shadow of the Earth 🌎? Shadow of the moon itself? Or plasma disc?

Alex, I'll take plasma disc for $50,000,000 a day. That's how much NASA gets paid to make cartoons and movies: $50,000,000 a day. So yeah, I'll take that one. Thank you, Alex.
