Current Aurora Forecast
for Whitehorse, Yukon
Forecaster's Comments: The solar wind velocity is currently low at 350 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 pretty respectable coming in at 1 protons/cm3. These 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 5/10: Aurora borealis activity is currently moderate. Weather permitting, decent northern lights displays will be visible directly overhead from Dawson City to Watson Lake and visible to the North and possibly overhead from Whitehorse.
Extended 3-Day Activity Forecast Description (Jul 4 to Jul 6): The geomagnetic field is expected to be quiet for the next three days (4-6 July).
