New Delhi, June 1 -- A strong geomagnetic storm is set to light up skies across much of the United States on Sunday night into early Monday, offering a rare opportunity for millions to catch a glimpse of the aurora borealis (Northern lights) far from the Arctic Circle.

According to the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center, the aurora borealis may be visible as far south as Alabama and Northern California. The most vivid displays are expected in the northernmost states, such as Michigan and Washington, while areas in the central Plains, Midwest, and even parts of the South and Mid-Atlantic may also see the glow on the northern horizon.

Clear skies will be key to witnessing the spectacle...
