Activity in past Januarys
Buffalo needs Kp 7 for the average oval edge to sit overhead. 7 of the 930 January days from 1996 to 2025 (1%) 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 6%. Buffalo sits at 52.0 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.
