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
Rovaniemi needs Kp 2 for the average oval edge to sit overhead. 703 of the 848 February days from 1996 to 2025 (83%) reached it in the GFZ Potsdam record, one of the three most active months for that level; storm days with Kp 5 or more made up 8%. Rovaniemi sits at 63.6 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 2.
