Activity in past Junes

Kumla needs Kp 4 for the average oval edge to sit overhead. 182 of the 900 June days from 1996 to 2025 (20%) reached it in the GFZ Potsdam record, one of the three quietest months for that level; storm days with Kp 5 or more made up 8%. Kumla sits at 58.2 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 4, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less.
