Aurora Forecast for Tuesday, April 24, 2012

Active: 0 1 2 3 4 5 6 7 8 9

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 solar event near the limb took us by surprise. The effects of this event were first felt early on the 23rd GMT, but the ejecta from the sun arrived just now (5:30pm Apr 23 GMT).

Tonight, April 23th, there will be aurora over the northern tier of the US, Northern UK, Southern Scandinavia, and Southern Alaska. Observers in Southern New Zealand and Tasmania should watch the sky tonight, if the activity proves to be long-lasting.
