Current Aurora Forecast
for Whitehorse, Yukon
Forecaster's Comments: The solar wind is currently travelling at a respectable velocity of 565 km/s. This provides a pretty good indicator that we can expect to see lights overhead. Additionally, particle density impacting the earth is pretty steady at 1 protons/cm3. Higher density numbers can help 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 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 (Jul 31 to Aug 2): The geomagnetic field is forecast to be mostly quiet with a few isolated periods of unsettled conditions for the next 3 days (31 July-02 August).
