How long it gets fully dark in Regina

  • The night after the 15th of each month: how long the sun stays more than 18° below the horizon. An aurora needs that dark sky – far north, summer has none at all.
  • January: 11 h 34 min · 19:20–06:55
  • February: 10 h 12 min · 20:06–06:18
  • March: 8 h 26 min · 20:53–05:19
  • April: 5 h 58 min · 21:58–03:57
  • May: 2 h 48 min · 23:30–02:18
  • June: never fully dark
  • July: 0 h 50 min · 00:39–01:29
  • August: 4 h 59 min · 22:33–03:32
  • September: 7 h 38 min · 21:04–04:42
  • October: 9 h 40 min · 19:54–05:34
  • November: 11 h 14 min · 19:06–06:20
  • December: 11 h 57 min · 18:55–06:52

How to see it

  • Look toward the pole: North in the northern hemisphere, south in the southern – away from city lights.
  • Use your phone's night mode: A camera shows colours the eye cannot see yet – the aurora often looks grey at first.
  • Be patient: The aurora comes in bursts, often 20–30 minutes apart.
  • Check the clouds: Without a clear view to the horizon nothing helps.

FAQ

  • What does the Kp index mean? The Kp index measures from 0 to 9 how disturbed Earth's magnetic field is. The higher it is, the farther the auroral oval moves toward the equator. From Kp 5 NOAA speaks of a geomagnetic storm.
  • When is the best time for the northern lights? Around magnetic midnight – in central Europe roughly between 10 pm and 2 am – and around the equinoxes in spring and autumn, when storms are a little more frequent.
  • How reliable is the forecast? The Kp forecast for the next hours is quite good, for two or three days only rough: solar storms take one to three days to reach Earth, and their exact strength often only shows shortly before.
