Something I noticed from the past few days. At ~1 AM the night sky is kind've blue. Normally, the night sky would be red due to the lights of the Chicago Metro Area, and it's a faint red glow. But recently it has been a full moon, does that factor in (yes I know it does, but how much). In the past, when I have seen full moons, normally the sky isn't a dark blue. Maybe I have not been paying attention to this, so discuss please.

The moon is the closest to earth it has been in the last 15 years.

I thought it was 30, and it won't be that close for another 30 yrs.

oh. thank you.
