Activity in past Julys
Kangasala needs Kp 4 for the average oval edge to sit overhead. 203 of the 930 July days from 1996 to 2025 (22%) reached it in the GFZ Potsdam record, 9th of 12 months; storm days with Kp 5 or more made up 9%. Kangasala sits at 59.1 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.
July across Finland
Kangasala ranks 6th in Finland for civil night on July 15, behind Helsinki at 2.9 hours. Coming from June (0.0 hours at Kangasala), July adds darkness, and the nights keep growing into August (6.1 hours on the 15th).
