Each cell is the night that starts on that date. Hours are civil-dark time with the moon below the horizon; the green rule scales with them. Green outline: new moon. Bone outline: full moon.
Activity in past Februarys
Hamar needs Kp 3 for the average oval edge to sit overhead. 455 of the 848 February days from 1996 to 2025 (54%) reached it in the GFZ Potsdam record, 5th of 12 months; storm days with Kp 5 or more made up 8%. Hamar sits at 60.5 degrees geomagnetic, inside SWPC's 60 to 75 degree band, where aurora can be seen on more than half of all nights. No storm is needed: by SWPC's rule the average oval edge is overhead at Kp 3.

Hamar ranks 12th in Norway for civil night on February 15, behind Alta at 14.1 hours. Coming from January (15.5 hours at Hamar), February loses darkness, and March brings shorter nights (10.7 hours on the 15th).
