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 Marchs
Quiet activity already puts the oval edge over Nuuk, so storm days matter more: 111 of the 930 March days from 1996 to 2025 (12%) reached Kp 5, one of the three most active months for that level. Nuuk sits at 72.5 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.
March across Greenland
Coming from February (13.4 hours at Nuuk), March loses darkness, and April brings shorter nights (6.8 hours on the 15th). The March equinox falls on March 20, 18:25 Nuuk time, inside the weeks SWPC links with larger storms.
