Current Aurora Forecast
The solar wind is currently travelling at an extremely quick pace at 731 km/s. With solar wind speeds this high we can certainly expect to see a pretty impressive light show. 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.
The Bz value of the Interplanetary Magnetic Field is current acting in a northward direction at a value of 4 nT which doesn't help the flow of energy particles into our atmosphere. The interplanetary magnetic field can change significantly in a short period of time. A change in direction to a southward or negative value can increase the potential for active aurora by allowing more energy particles to enter our upper atmosphere. In this scenario we can expect to experience aurora sub-storms and will be reflected by a significant jump in the aurora activity level indicated on this page.
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 (Oct 8 to Oct 10): The geomagnetic field is expected to be at active to severe storm levels on Oct 9 (08 Oct), quiet to minor storm levels on Oct 10 (09 Oct) and quiet to active levels on Oct 11 (10 Oct).
