The next big storm
One push whenever NOAA forecasts a G1+ geomagnetic storm within 48 hours — wherever you are. On a big night the aurora reaches far south of its usual latitudes.
A calm night. This Kp means a faint glow only at the highest latitudes — Svalbard, north Greenland. Below 66°N the sky most likely stays empty tonight.
Most northern European cities use low lighting, including street lamps; this reduces light pollution and lets the northern lights be seen even from within the city. Still, for the best experience go to a dark area away from the city lights. If that's not possible, at least move to a spot where you leave the bright lights behind you. The human eye is sensitive to bright light and takes time to adapt to the dark.

Whether you'll see it depends on geomagnetic latitude, not map latitude — which is why Yellowknife sees the aurora as readily as Tromsø, and Ushuaia needs a major storm. Both hemispheres, live against tonight's Kp.
