Activity in past Novembers
New Rochelle needs Kp 8 for the average oval edge to sit overhead. 8 of the 900 November days from 1996 to 2025 (1%) 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%. New Rochelle sits at 50.1 degrees geomagnetic. The lowest NOAA storm level whose typical viewing latitude reaches it is G3 (Kp = 7). By SWPC's rule the average oval edge is overhead only at Kp 8.
