Activity in past Aprils

Quiet activity already puts the oval edge over Badger, so storm days matter more: 106 of the 900 April days from 1996 to 2025 (12%) reached Kp 5, 4th of 12 months. 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.

Badger ranks 10th in United States for civil night on April 15, behind Buffalo at 9.5 hours. Coming from March (10.4 hours at Badger), April loses darkness, and May brings shorter nights (0.0 hours on the 15th).
