G2 geomagnetic storm watch issued as solar eruption nears Earth

Original: G2 geomagnetic storm watch issued as CME heads for Earth — northern lights possible across northern US Oct. 8-9

Forecasters have issued a G2 geomagnetic storm watch after a coronal mass ejection was detected heading toward Earth, with arrival expected around October 8-9. The disturbance could push the aurora borealis unusually far south, making the northern lights visible across northern US states. Skywatchers are being told to watch for clear skies on those nights.

Why now: A solar storm could make the northern lights visible farther south than usual on Oct. 8-9, prompting wide interest among skywatchers.
