Current Aurora Forecast
The solar wind is currently travelling at a respectable velocity of 690 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 2 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 2 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 4/10: Aurora borealis activity is currently moderate to low. Weather permitting, northern lights displays will be visible directly overhead from Dawson City to Watson Lake and visible to the north from Whitehorse.
Extended 3-Day Activity Forecast Description (Dec 10 to Dec 12): The geomagnetic field is expected to be at unsettled to minor storm levels on Dec 11 (10 Dec), quiet to active levels on Dec 12 (11 Dec) and quiet to unsettled levels on Dec 13 (12 Dec).
