Activity in past Julys
No whole Kp puts the average oval edge over Burnie by SWPC's rule, so the GFZ record has no threshold to count for July. Burnie sits at 48.0 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.
July across Australia
Coming from June (13.6 hours at Burnie), July loses darkness, and August brings shorter nights (12.5 hours on the 15th).
