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.
10 locations currently sit inside the auroral oval.
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.
