Saturday night’s northern lights display follows “strong” radio blackouts on Friday, an event that NOAA said briefly disrupted high-frequency radio communications and radio contact after an X1.1 solar flare—classified as the most intense— emitted from the sun’s surface on Thursday.

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.

Aurora? Sorta! The northern lights were trending on social media Thursday, but don't get your hopes up too much. Only a limited region of the U.S. will be able to see it.
