Aurora chasers are on high alert for geomagnetic storm conditions overnight with northern lights possible at mid-latitudes.

The northern lights may be visible from parts of the U.S. on Tuesday. According to the National Oceanic and Atmospheric Administration (NOAA), the arrival of a so-called "corotating interaction region" could trigger "G2"-class geomagnetic storms.

Geomagnetic storm conditions may bring the northern lights to more U.S. states along the Canadian border on Wednesday, with similar auroral activity expected later this week, according to the National Oceanic and Atmospheric Administration.
