Northern Lights Shine Across Northern U.S. and New England During Geomagnetic Storm

The aurora borealis remains visible in northern states as geomagnetic activity decreases to G1-class on March 26, 2025.

A G2-class geomagnetic storm on March 25, 2025, caused by high-speed solar winds from a coronal hole, brought the northern lights further south into parts of the northern U.S. and New England.
The auroral displays were enhanced by the Russell-McPherron effect during the equinox, which increased Earth's susceptibility to solar wind.
NOAA forecasts a decrease in geomagnetic activity to G1-class by the evening of March 26, but northern lights may still be visible under clear skies and low light pollution.
Residents in northern states, including Vermont, New Hampshire, and Maine, reported sightings of vibrant auroras on March 25, with potential for additional visibility tonight.
The current solar maximum, which began in late 2024, has led to heightened auroral activity, marking a 500-year peak in 2024 for northern lights displays.
