Current Aurora Forecast

for Canada's North

The solar wind velocity is currently low at 341 km/s. While this is certainly not the only indicator for a spectacular aurora display it doesn't help to increase our chances. However, particle density impacting the earth is very high coming in at 4 protons/cm3. These relatively high density numbers will help to improve the overall spread of the aurora we see.

There is a significant southward pointing Bz value of 2 nT that is working to cancel out our Earth's magnetic field. As the southward Bz value increases this helps to open a 'door' in our magnetosphere allowing energy particles from the solar wind to more easily penetrate our atmosphere. This is a good indicator for the current availability of active aurora.

Aurora Activity Level 6/10: Aurora borealis activity is currently moderate to elevated. Weather permitting, good northern lights displays will be visible directly overhead from areas above magnetic 66th.

Extended 3-Day Activity Forecast Description (Aug 23 to Aug 25): The geomagnetic field is expected to be at quiet levels on days one, two, and three (23 Aug, 24 Aug, 25 Aug).
