Northern Lights Now – The Space Weather Prediction Center has issued a G1 Geomagnetic storm watch for potential aurora on April 30. This means aurora may be visible for northern latitudes late on the 29th for North American viewers. The predicted display is due to the passing of high speed solar wind from a coronal hole. As of this writing, the period of expected activity is from around mightnight GMT until 9am GMT (or about sunset to early morning on the East Coast of North America). Here is the NLN’s auroraCast:
