The northern lights were visible across a large swath of the United States on Tuesday night, including here in the Delaware Valley, thanks to a severe geomagnetic storm that hit the Earth's magnetic field.  

A G4 (severe) geomagnetic storm watch remains in effect on Wednesday. According to the National Oceanic and Atmospheric Association (NOAA), the northern lights could be visible across the northern half of the country and even as far south and west as Alabama and California.

Locally, NEXT Weather meteorologist Kate Bilo says the geomagnetic storm's intensity will be slightly lower tonight, so the best viewing conditions will be farther north and closer to the Poconos. It's possible we could see the lights closer to the city, but it's more likely to catch a glimpse of the aurora away from light pollution.

CBS News Philadelphia's Joe Holden shared a shot of the aurora he took in Havertown, Pennsylvania, on X Tuesday night just after 11 p.m.

In New Jersey, red-hued lights were visible in Maurice River Township.
