[João Costa > CT1FBF]

Geomagnetic storm sparks auroras over the USA

On Friday, April 10th, a G2-class geomagnetic storm erupted.
Northern Lights spilled across the Canadian border into the USA, where
auroras were photographed as far south as Colorado.

At the time of this alert, storm conditions are still underway with a
possibility for more storming when a belated CME arrives later in the day.
