Many Americans who gaze skywards this Halloween weekend could be in for a treat.
It’s possible the northern lights will be visible over Washington state, the far Northeast and the Upper Midwest thanks to a solar flare and “coronal mass ejection,” officials said Friday.
A G3 — or strong — “geomagnetic storm watch” was issued for Saturday and Sunday by the National Oceanic and Atmospheric Administration.
The agency’s Space Weather Prediction Center said the coronal mass ejection is expected to reach the Earth on Saturday, and effects are likely to continue into Sunday.
