Aurora borealis sightings were reported as far south as Arkansas and Alabama on Monday night thanks to a severe geomagnetic storm.

Earth is still reverberating from the colossal coronal mass ejection ( CME) that struck on Jan. 19, triggering dazzling aurora displays worldwide. And while tonight's show (Jan. 20) may be somewhat more subdued, the solar storm isn't quite over — so keep your camera batteries charged and your aurora alerts on.

A severe geomagnetic storm watch is in effect Monday night as people prepare for northern lights to dazzle the night sky across the U.S. Here's where.

The Northern Lights are mostly visible near the Arctic Circle but at times of high solar activity can be seen in other areas. Photos sent in to the BBC show dazzling displays of colourful light in places including Penmachno in Conwy, Llandegla in Denbighshire, and Narberth in Pembrokeshire.
