The astrophotographer I worked with earlier this month, Jeanine Holowatuik instagram.com/jeanine.holowatu… northernescapephotography.com/… sent me some horrifying (Halloween-levels of scary) time lapse movies she took of Comet Lemmon.

Why horrifying? Starlink.

I wrote a paper ui.adsabs.harvard.edu/abs/2022… a few years ago with Aaron Boley and @hannorein and our horrifying predictions for light pollution from satellites are matching up perfectly, Lemmon was low in the northwest for this video: mediaspace.uregina.ca/media/La…

I'd even argue we were a bit too conservative/optimistic in our assumptions of satellite brightnesses. I've never wanted to be wrong in a scientific paper before, but I sure wanted to be wrong about that one.

Shit.

Visibility Predictions for Near-future Satellite Megaconstellations: Latitudes near 50° Will Experience the Worst Light Pollution

Megaconstellations of thousands to tens of thousands of artificial satellites (satcons) are rapidly being developed and launched.

This looks almost exactly like our simulations from 2022:

If anyone wants to play with the simulations themselves, you can download our free iOS app "Mega Constellations" apps.apple.com/us/app/mega-con…. Although by now you might also just step outside and look up 😢
