City forecast
This forecast names cities so readers can plan around a local viewing window.
Paamiut, Kulusuk and Tasiilaq reach 17:00–20:00 GMT-1 during NOAA's Kp 6.0 global peak. This can include late-afternoon light, so it is not automatically a dark observation window.
Narsarsuaq, Qaqortoq and Sisimiut have the same time zone. NOAA then forecasts Kp 5.67 from 20:00–23:00 GMT-1, a later evening interval; local darkness, clouds and conditions still decide visibility.
What to do
- Note the Kp 6.0 peak at 17:00–20:00 GMT-1 on October 9.
- For an evening option, check 20:00–23:00 GMT-1, forecast at Kp 5.67.
- Check local darkness, the live city forecast and choose an open, low-light viewing spot.
