Forecast: Auroral activity will be active. Weather permitting, active auroral displays will be visible overhead from Inuvik, Yellowknife, Rankin and Igaluit to Juneau, Edmonton, Winnipeg and Sept-Iles, and visible low on the horizon from Vancouver, Great Falls, Pierre, Madison, Lansing, Ottawa, Portland and St. Johns.
Forecaster Comments: A very large solar event took place early on the 25th of February UT. It was located near the east limb of the sun facing away from the Earth, so the effect on the Earth may be diminished somewhat. However, we expect enhanced auroral activity when the disturbance arrives late in the evening of the 26th of February UT (estimated 48 hour travel time). For North America, this means aurora may reach index Kp=5 or more so as to be visible over the northern half of the US during the night of the 26th/27th. Activity could also occur on the night of 27th/28th.
