WATCH: What to expect as NOAA issues strong geomagnetic storm watch

Article excerpt

The National Oceanic and Atmospheric Administration has issued a strong geomagnetic storm watch as three coronal mass ejections head toward Earth. The solar activity could push the northern lights farther south than usual, potentially visible to millions of Americans in the lower 48 states. NOAA's Space Weather Prediction Center is tracking the incoming disturbances, which could also affect power grids and communications systems during the peak viewing window.
