Northern lights may light up US, Canada tonight amid G1-G2 storm

The northern lights could put on another show across parts of the United States and Canada this week as a coronal mass ejection (CME) linked to a long-duration M1.4 solar flare heads toward Earth.NOAA’s Space Weather Prediction Center has issued a G2 (moderate) geomagnetic storm watch for October 9, forecasting G1 (minor) to G2 conditions as the CME reaches Earth. The eruption originated from active region AR4549 on the Sun on October 6.The forecast could give skywatchers another opportunity to see the aurora borealis, particularly across northern parts of the US and Canada.
