Aurora forecast
By location
Kp is a planetary number — it doesn't tell you what's above your head. Pick a place for a visibility answer built from its geomagnetic latitude, tonight's cloud cover, and the current Kp of 3.0.
Under the auroral oval right now
At the current Kp the oval extends over 45 locations. That puts aurora within reach on a dark, clear night — Kp says how far the oval reaches, not exactly where the arc is at this minute.

One email when a geomagnetic storm makes aurora likely at your latitude. No digest, no noise.
The Kp figure beside each place is what it takes for aurora to clear the horizon there, derived from its geomagnetic latitude using the NOAA auroral-oval boundary table. Kp data from NOAA SWPC.
