Activity in past Aprils
No whole Kp puts the average oval edge over Warragul by SWPC's rule, so the GFZ record has no threshold to count for April. 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.
April across Australia
Coming from March (10.7 hours at Warragul), April adds darkness, and the nights keep growing into May (12.9 hours on the 15th).
