“The Northern Lights may be seen from as many as 24 U.S. states down to mid-latitudes — such as Oregon, Illinois and Pennsylvania — overnight on Monday, Jan. 19, through Tuesday, Jan. 20, according to a forecast by the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center. … The forecast is for a ‘strong’ G3 or possibly a ‘severe’ G4 geomagnetic storm on NOAA’s five-level Space Weather Scale, as a ‘full halo CME’ — an Earth-directed coronal mass ejection — interacts with Earth’s magnetic field. … The CME, a cloud of charged particles ejected from the sun, left the sun on Sunday, Jan. 18, in the wake of a massive X1.9-class solar flare.” (01/19/26)
