Activity in past Aprils

Quiet activity already puts the oval edge over Akureyri, so storm days matter more: 106 of the 900 April days from 1996 to 2025 (12%) reached Kp 5, 4th of 12 months. Akureyri sits at 69.7 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 0.
