About PolarPeek
Who makes PolarPeek, why it exists and how the forecasts are made.
PolarPeek is an independent night-sky almanac. It answers one question well: is it worth going outside tonight? For the aurora, the Moon, the planets, the ISS and the big yearly events, it combines official data with careful calculation and explains the result in plain language, in eight languages.
Principles
- Official sources only. Space weather from NOAA’s Space Weather Prediction Center and GFZ Potsdam, weather from the Norwegian Meteorological Institute and the US National Weather Service, ISS orbits from NASA. Every source and licence is listed on the sources page.
- Calculations you can check. Positions, phases and eclipses come from the open-source astronomy-engine library. The methodology explains the aurora model and its limits.
- Honest uncertainty. The aurora cannot be promised. We say yes, maybe or unlikely and show why.
- No accounts, no tracking. Your location stays in your browser.
Who is behind it
PolarPeek is built and maintained by Paulius Petrusauskas in Vilnius, Lithuania, a software developer who has spent too many cold nights waiting for the northern lights. Corrections and ideas are welcome at hello@polarpeek.com.
