"AURORA UPGRADE! NOAA has upgraded the G2 (Moderate) Geomagnetic Storm Watch to G3 (Strong) for Wednesday, April 16th. This upgrade, on paper, would allow the northern lights to be visible even across mid latitude parts of the U.S.
UPDATE: A piece of this expected energy has arrived at Earth, possibly the first of several waves. This very much opens the window of opportunity for auroras tonight if skies are clear where you are located."
