Aurora Forecast for Monday, September 15, 2014
Forecast:Auroral activity will be moderate. Weather permitting, moderate displays will be visible overhead from Inuvik, Yellowknife, Rankin, and Igaluit to as far south as Whitehorse, Ft. McMurray, James Bay and visible low on the horizon as far south as Prince Rupert, Calgary, Minot, Bemidji, Stevens Point, Traverse City and Quebec City, Canada.
Forecaster Comments: The effects of a solar event on the 9th of September facing roughly toward Earth should reach Earth around midnight on September 11th UT. Another, larger event occurred on September 10th that should have higher velocity. The effects from the latter event may reach Earth at the same time. Even if it is later, disturbances should be large and last long enough to result in increased auroral activity anytime for three or four days. The result is that aurora watchers should watch http://www.swpc.noaa.gov/ovation/ for the next five to seven days. We will post more accurate predictions when the observations of the solar activity have been analyzed.
