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 Mays
Quiet activity already puts the oval edge over Bodø, so storm days matter more: 97 of the 930 May days from 1996 to 2025 (10%) reached Kp 5, 6th of 12 months. Bodø sits at 66.0 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.
