- Far-northern locations can be worth monitoring, but the forecast does not rank cities or provide a guaranteed viewing hour. Check darkness and cloud cover locally.
A Kp forecast is global; darkness and clouds are local.
Churchill, Thompson, Fort McMurray, Hay River, Rankin Inlet, Edmonton, Dawson City and Grande Prairie remain useful places to monitor. Their viewing conditions differ with darkness, cloud cover and local horizon.
AuroraMe's model peaks near 21:00 UTC, and NOAA's September 9 outlook reaches Kp 5.67 at 21:00–00:00 UTC. A local night can fall on a different calendar date than the UTC forecast period, so use local time to check darkness rather than as a promised viewing window.
