Current Aurora Forecast
for Canada's North
The solar wind velocity is currently low at 438 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 1 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 (Sep 23 to Sep 25): The geomagnetic field is expected to be at quiet to unsettled levels on days one, two, and three (23 Sep, 24 Sep, 25 Sep).
