Incoming CME could spark impressive northern lights over the northern US tonight

An incoming coronal mass ejection (CME) is forecast to hit Earth today, potentially triggering geomagnetic storms.
Forecasters expect minor to strong geomagnetic activity, possibly reaching G3 later in the day.
The strongest aurora activity is expected between 11 a.m. and 2 p.m. EDT, with elevated activity into the evening.
NOAA issued a G3 geomagnetic storm watch for June 8 and a G2 watch for June 9.
If conditions align, auroras could be visible farther south than usual, including several northern U.S. states.
Viewing conditions matter; cloud cover and light pollution can affect visibility.
For real-time forecasts, space-weather apps like My Aurora Forecast & Alerts can help.
Experts caution that timing shifts in CME arrival can alter viewing opportunities.
Aurora visibility is not guaranteed even during strong geomagnetic storms.
