Current Aurora Forecast

The solar wind velocity is currently low at 409 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 13 protons/cm3. These relatively high density numbers will help to improve the overall spread of the aurora we see.

There is currently a very strong southward pointing Bz value of 7 nT that is cancelling out the protective effects our Earth's magnetic field. The increased southward Bz value forces open a 'door' in our magnetosphere letting energy particles from the solar wind easily penetrate our atmosphere. This is an excellent indicator for the current availability of active aurora.

Aurora Activity Level 7/10: Aurora borealis activity is currently elevated. Weather permitting, larger northern lights displays will be visible directly overhead from Dawson City to Watson Lake and Whitehorse.

Extended 3-Day Activity Forecast Description (Sep 3 to Sep 5): The geomagnetic field is expected to be at quiet to active levels on Sep 4 (03 Sep) and quiet to unsettled levels on days two and three (04 Sep, 05 Sep).
