5% · context, not an aurora score input
NOAA OVATION supplies the geographic activity grid for both hemispheres. Indicators are not personal viewing probabilities. NOAA says bright aurora may be visible up to 1,000 km away under suitable conditions; the nearby maximum is conditional context, not a guarantee. SnapCosmos accepts observations up to two hours old and targets no more than 20 minutes past or 90 minutes ahead. Moonlight remains separate context; no new scoring input is introduced.
Full assessment basis: The sky is not astronomically dark at the forecast time. The current short-term activity map cannot predict the later dark hours; only exceptionally bright aurora may show through twilight. Darkness boundaries are astronomical geometry, not a promise of aurora activity during those hours.
Northern lights in Fairbanks: what you should know
Under the oval, so darkness and cloud decide
Fairbanks lies close to the auroral oval, so modeled activity near the city is common in the dark season. That shifts the question from 'is there aurora?' to 'is it dark and clear at the forecast time?' The University of Alaska Fairbanks Geophysical Institute publishes its own regional forecast alongside NOAA's.
For weeks around the June solstice, the sky over Fairbanks never reaches astronomical darkness. In that season the darkness boundaries below read 'no astronomical darkness', and only exceptionally bright aurora could show through the twilight.
