City forecast
This forecast names cities so readers can pair the October 9 window with a local visibility check.
Wainwright, Kiana and Noorvik receive the Kp 6.0 global peak during 10:00–13:00 AKDT, in daylight. The later 19:00–22:00 AKDT evening slot is forecast at Kp 3.67 and may begin in twilight.
Ambler, Noatak and Buckland follow the same Alaska time. A global Kp forecast does not guarantee visibility at a city; check local darkness, clouds and the live city forecast before deciding to travel.
What to do
- Do not treat the 10:00–13:00 AKDT Kp 6.0 peak as a dark viewing interval.
- For an evening option, check 19:00–22:00 AKDT, forecast at Kp 3.67.
- Check local darkness, the live city forecast and choose an open, low-light viewing spot.
