galaxosA live forecast for 243 places. Kp is 0.7 right now (quiet). On NOAA's forecast for each place's own night, the aurora is within reach of 101 of them tonight. Open a place for its clouds and darkness tonight.
Each country's places, easiest first. “Within reach” means tonight's activity is strong enough for the northern lights there; the place's page adds clouds and darkness.
One page per country, and per state, province or nation with enough places.
Kp is a 0 to 9 number for how disturbed Earth's magnetic field is. The higher it goes, the further from the poles the aurora can be seen. Data from NOAA SWPC.
