This is of the day New York's power went out, I went home from work early that day

I'm not sure if it's brighter than normal.

Hi. The average brightness has been increasing as more area gets developed. I don't think the addition of holiday lighting would add more than a few percent in the larger cities and almost none in the less developed parts of the country.

KoppiBlinkFlickRick from the Andromeda Galaxy sent me this spacemail by subspace communication:
"Hi David! In response to your question, we can see the USA's Christmas lights approximately two million years after Christmas!"
Hope that helps.
