What is this random spot with seemingly nothing around it in Russia?

"...however, at any given time, several thousand transient workers support the Prudhoe Bay oil field."

The bright spot is bigger than the bright spot over Paris and London though. Do they just leave the lights on 24/7 in the bay?

Oil flares.

I like this. I think it would be also useful to add isolines for brightness of various astronomical objects to the map. I want to easily understand where I need to go to see Milky Way for example.

It's not like nothing can be done about light pollution. For example Germany has a law about light pollution, and it shows on this map. It less polluted than its neighbours, although it has higher population density and urbanization level.

Flagstaff vs. Prescott in Arizona is another good example. Flagstaff has strict output per area limits, Prescott has none, while the density of both areas is similar.

Resources like this (and as others have mentioned, Dark Site Finder) are very useful for astrophotography, especially for a hobbyist like myself. Many don't realize how relatively close they live to areas with great nighttime viewing conditions.

For example, upstate New York has some great viewing locations, so even if you live in NYC it's an easy weekend trip. Here's a shot I took of the Milky Way taken from such a site (one of the darker spots in the map): https://www.lumathon.com/photo/_qTYviEhy/Colors-of-the-Milky...

Edit: a few more of my other shots of the night sky for anyone interested, various locations, all of which were scouted using a light pollution map like the one posted -- https://www.lumathon.com/dan/photos/tag/stars

Are you using a framework for your map or did you come up with those tooltip dissolving into tic-tac-toe animations yourself?

Typo corrected. I am not the creator and meant to write "It uses"

Is this not just a population map? https://m.xkcd.com/1138/

mostly but not completely and the exceptions are interesting.
