- Aurora on a clear, dark night
- ~75%
- Typical season
- September – March
The plan score is a long-term statistic, not a forecast for specific nights. Solar activity can't be known beyond about 3 days.
Equinox periods (late March and late September) are statistically better for geomagnetic storms.
How is this calculated?
Per night: climatological clear-night probability × chance of aurora on a clear dark night by magnetic latitude × darkness (sun below −12°; zero under 2 hours) × moon effect (up to 30% lower when a bright moon is up). Trip chance = 1 − Π(1 − nightly chance).
