Projections from NASA and NOAA suggest northern lights displays will be more visible in more U.S. states through early 2026, after activity on the sun’s surface

A severe geomagnetic storms is expected to trigger a much wider area of visible Northern Lights in the U.S. on Sunday and Monday nights, NOAA said.

The aurora's are back! And may be visible throughout the weekend. The University of Alaska and NOAA track auroras using the Kp-index , a global auroral activity indicator which has a scale from 0 to 9. It measures the fluctuations in the Earth's magnetic field, tied to specific geographic locations.
