Current Aurora Forecast
for Canada's North
The solar wind velocity is currently low at 368 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 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 5/10: Aurora borealis activity is currently moderate. Weather permitting, decent northern lights displays will be visible directly overhead from areas above magnetic 66th.
Extended 3-Day Activity Forecast Description (May 21 to May 23): The geomagnetic field is expected to be at predominately quiet levels for May 21 (21 May). By days two and three (22 - 23 May), quiet to unsettled levels with a slight chance for isolated active periods are expected due to coronal hole high speed stream effects coupled with the arrival of the 18 May CME.
