Activity in past Februarys
Drogheda needs Kp 5 for the average oval edge to sit overhead. 67 of the 848 February days from 1996 to 2025 (8%) 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 8%. Drogheda sits at 56.5 degrees geomagnetic. By SWPC's rule the average oval edge is overhead at Kp 5, and aurora is usually visible on the northern horizon at G1 (Kp 5) or less.
