A potent geomagnetic storm is anticipated for Sunday night, likely allowing northern lights visibility across the northern half of the contiguous U.S., potentially reaching as far south as northern California and Alabama. Linked to a solar flare observed on Friday, this storm, influenced by a coronal mass ejection, is expected to last until late Monday. Officials warn of possible G3 or G4 storm impacts, which could disrupt power systems and satellite functions. Viewing conditions are best at night in dark areas due to solar wind interactions with the Earth's magnetic field.
A powerful geomagnetic storm this Sunday night may allow northern lights to be visible across parts of the United States, even in southern states.
The geomagnetic storm, driven by a coronal mass ejection, may cause disruptions in power systems and satellite operations.
