Activity in past Januarys

Quiet activity already puts the oval edge over Badger, so storm days matter more: 58 of the 930 January days from 1996 to 2025 (6%) reached Kp 5, one of the three quietest months for that level. Badger 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.
