Best Viewing Season in Montana
Glasgow averages 2.1 clear nights a year with Kp at its threshold — aurora here is an event, not a season. Figures below are for Glasgow, the best-placed of the 8 locations we track in Montana. They describe a typical year built from the 1996-2026 planetary Kp record and the 2001-2020 cloud normal — not a forecast. Each city page shows tonight's live cloud, moon and darkness instead.
