What Rochester Hills needs
Rochester Hills sits at a magnetic latitude of 51.7 degrees, so the aurora can reach its northern horizon at about Kp 7.2. Each step above that brings it higher in the sky. Kp is NOAA's 0-9 index of geomagnetic activity; the higher it goes, the farther south the aurora can be seen.
How to see it from Rochester Hills
- Drive out past the edge of Rochester Hills's lights and face north, with a clear view of the horizon.
- The best hours are usually 10 pm to 2 am, and clouds hide everything, so check the sky too.
- A phone camera on a long exposure often shows color the eye misses.
Forecast: NOAA Space Weather Prediction Center 3-day Kp forecast, refreshed every few hours. The Kp needed comes from the city's AACGM-v2 magnetic latitude; the visibility rule is approximate.
