Activity in past Novembers

Greater Sudbury needs Kp 6 for the average oval edge to sit overhead. 40 of the 900 November days from 1996 to 2025 (4%) reached it in the GFZ Potsdam record, one of the three most active months for that level; storm days with Kp 5 or more made up 10%. Greater Sudbury sits at 55.6 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 6, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less.
