“Lower 48” sightings of auroras

On Saturday, April 11th, a coronal mass ejection (CME) hit Earth’s magnetic field. The impact caused a G2-class geomagnetic storm and, for the first time this year, ignited auroras over the continental United States.

“Lower 48” sightings of auroras are a sign: The deep solar minimum of 2008-2009 has come to an end and a new solar cycle is gaining strength. If forecasters are correct, Solar Max is just two to three years away. From spaceweather
