Activity in past Marchs

Quiet activity already puts the oval edge over Fairbanks, 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. Fairbanks sits at 65.7 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.
