Can you see the northern lights from Cluj-Napoca?
Cluj-Napoca is at about 45° geomagnetic latitude. Aurora can appear low over the northern horizon when the Kp index reaches about 7.6, and overhead from about Kp 9.0. That means g3 strong storm conditions or stronger.
For the best chance, wait until it is fully dark, leave the town lights behind and face north with a clear, low view of the horizon. Displays often come in bursts of 10 to 30 minutes, so stay out for a while. Your phone's night mode may show colour before your eyes do.
Kp data: NOAA Space Weather Prediction Center, updated 14 Nov 18:15 UTC. The outlook uses a centred-dipole geomagnetic latitude and a rule of thumb for the edge of the auroral oval. Real displays vary, so treat it as a guide. Sources and methods.
