Do you put your holiday lights up right after Thanksgiving?
This map compares averaged nighttime brightness before Thanksgiving (Nov 24th – 26th) to averaged brightness a few days after (Nov 28th – Nov 30th).
**Each location is compared to itself over time**, so permanent city lighting fades into the background and locations that increased in brightness are highlighted rather than places that are already bright overall.
Not drawing strong conclusions here – mostly curious what spatial patterns or regional differences people notice when they zoom in! Could the increase be tied to a mix of holiday decorations and Thanksgiving weekend activity even Black Friday?
