The Night Sky Comes Alive: A G-2 Geomagnetic Storm May Unleash Aurora Borealis Over Northern Hemisphere

On April 23, a geomagnetic storm may trigger an aurora borealis over the Northern Hemisphere from the evening until the next morning.

Some states in the U.S.-Canadian border region may most likely witness the Northern Lights.

A G-2 level on the Geomagnetic Storm Impact scale is expected to hit Earth, according to NOAA's Space Weather Prediction Center.

A G-2 event is fairly common and happens about every 360 days over an 11-year cycle.

Northern power systems may experience voltage alarms, spacecraft may exhibit orbit changes, and radio frequencies can fade at higher latitudes, according to NOAA.

Clear night skies in some northern states like from Washington to Maine, may have a chance to see the aurora.

On Friday, a solar flare erupted on the sun and was directed towards Earth, triggering an aurora borealis that was visible in 18 states.

The best viewing time for the Northern Lights is typically between 10 p.m. and 2 a.m. local time.
