A geomagnetic storm produced bright auroras that were visible much farther south than usual overnight Sunday and Monday.
A video shared by Twitter user @pan_alaska shows a view of the aurora borealis, or Northern Lights, from Big Lake, Alaska, on Sunday night.
The National Oceanic and Atmospheric Administrations Space Weather Prediction Center reported a strong geomagnetic storm overnight Sunday into Monday. The geomagnetic storm was rated G3, or strong, on a scale with G5 being the most extreme.
The SWPC said ongoing storming was likely to produce moderate G2 conditions Tuesday. The agency said the storms strength comes from a combination of solar events occurring simultaneously.
High solar wind speeds were already forecast due to a hole in the suns corona producing a recurrent high-speed stream, and two coronal mass ejections occurred on Feb. 25 and Feb. 26. The second CME was produced by a medium-intensity M6.2 solar flare.
