Activity in past Marchs
Quiet activity already puts the oval edge over Mo i Rana, so storm days matter more: 111 of the 930 March days from 1996 to 2025 (12%) reached Kp 5, one of the three most active months for that level. Mo i Rana sits at 65.2 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 1.
