Current Aurora Forecast

The solar wind velocity is currently low at 451 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 3 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 Dawson City to Watson Lake and Whitehorse.

Extended 3-Day Activity Forecast Description (Jul 28 to Jul 30): The geomagnetic field is expected to be at quiet to unsettled levels on days one and three (28 Jul, 30 Jul) and quiet to active levels on Jul 30 (29 Jul).
