Activity in past Aprils
Brooklyn Park needs Kp 7 for the average oval edge to sit overhead. 19 of the 900 April days from 1996 to 2025 (2%) 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 12%. Brooklyn Park sits at 53.6 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 7.
