Aurora forecast
Plan from tonight to the ten-day outlook.
GreenHalos separates tonight, the three-day forecast and the ten-day outlook, avoiding exact local claims when a source supports only broad geomagnetic context.
Tonight to three days
NOAA forecasts describe geomagnetic activity; local darkness and cloud still determine whether observing is practical.
Long-range outlook
Days four to ten are low confidence and show no fabricated future oval, exact probability or precise local timing.
