The holidays are lighting up already. Space weather forecasts have suggested that several states, including parts of New York, may get yet another rare opportunity to view the aurora borealis early this week.

Geomagnetic storm conditions are expected on Saturday night, likely pulling the northern lights further south below the Canadian border, according to a National Oceanic and Atmospheric Administration forecast. (Here’s an updated forecast for Sunday night.)

Displays of Northern lights are possible on Sunday night across the Northern U.S. due to a geomagnetic storm underway.

The Northern Lights, also known as aurora borealis, are created when charged particles from the sun interact with Earth's atmosphere. These charged particles are called "solar win

The Northern Lights are caused by the solar wind, a stream of charged particles from the sun interacting with Earth’s magnetic field. As charged particles strike Earth’s magnetic field, they accelerate down its magnetic field lines at the north and south poles to create ovals of green and red.
