Activity in past Julys

No whole Kp puts the average oval edge over Frankston East by SWPC's rule, so the GFZ record has no threshold to count for July. Frankston East 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.

July across Australia

Coming from June (13.4 hours at Frankston East), July loses darkness, and August brings shorter nights (12.4 hours on the 15th).
