Which states have the best aurora chances โ and what KP index you need
During Solar Cycle 25's peak (2025โ2026), G3โG5 storms occur monthly. States that rarely see auroras are now reporting sightings:
Solar Cycle 25 reaches its maximum in 2026 โ the most intense sunspot activity in two decades โ driving spectacular auroras visible across much of the US.
Michigan's Upper Peninsula, Maine, Minnesota, Montana, Alaska, and the Dakotas offer the clearest northern lights views when geomagnetic storms strike.
Coronal mass ejections shoot billions of tons of charged particles toward Earth. Our magnetic field deflects most โ but funnels some toward the poles, painting the sky.
Spring and fall equinoxes enhance geomagnetic activity. March and September 2026 already broke 50-year aurora visibility records across 35 US states.
