Each cell is the night that starts on that date. Hours are civil-dark time with the moon below the horizon; the green rule scales with them. Green outline: new moon. Bone outline: full moon.
Activity in past Junes
Quiet activity already puts the oval edge over Yellowknife, so storm days matter more: 73 of the 900 June days from 1996 to 2025 (8%) reached Kp 5, 9th of 12 months. Yellowknife sits at 68.5 degrees geomagnetic, inside SWPC's 60 to 75 degree band, where aurora can be seen on more than half of all nights. No storm is needed: by SWPC's rule the average oval edge is overhead at Kp 0.
