Activity in past Mays
No whole Kp puts the average oval edge over Warragul by SWPC's rule, so the GFZ record has no threshold to count for May. Warragul sits at 45.1 degrees geomagnetic. The lowest NOAA storm level whose typical viewing latitude reaches it is G4 (Kp = 8, including a 9-). Even Kp 9 does not put the average oval edge overhead by SWPC's rule.
May across Australia
Coming from April (11.9 hours at Warragul), May adds darkness, and the nights keep growing into June (13.4 hours on the 15th).
