Waxing Gibbous

 

I stepped outside on Halloween to see just what you'd expect on this holiday: a spooky Halloween Moon. Unfortunately, it wasn't a Full Moon, it was a Waxing Gibbous. But the way the clouds were situated around it, with bright light shining through only made me think of ghouls and goblins galore.

I did some quick measurements: it was 30° above the horizon at 170° S. I noticed that it seemed a bit smaller than normal, and I wondered why it had finally come back up from beneath the horizon as it had been in previous nights.
