Northern lights may be visible across 18 states tonight

Tonight offers a chance to witness the northern lights across parts of the U.S.

Northern lights expected to shine in 18 states tonight

A solar storm may allow northern lights to be seen in states from Alaska to Illinois on the night of August 7-8. This possibility arises from an incoming coronal mass ejection (CME) that could lead to geomagnetic storm conditions. Forecasters from NOAA predict a chance of minor to moderate geomagnetic storms, hinting at the potential for aurora displays in the northern U.S., depending on weather and illumination conditions. The timing of the CME's arrival remains uncertain, creating two potential viewing windows for enthusiasts. States with the best chance to observe the auroras include Alaska, Montana, North Dakota, and more, though auroras can sometimes appear farther south than expected.

The anticipated northern lights highlight not just a beautiful natural phenomenon but also the unpredictable nature of space weather. As communities prepare for a celestial light show, the event underscores humanity's ongoing fascination with astronomy and science. While forecasts can provide guidance, the elemental unpredictability of solar activity serves as a reminder of nature's complexity. For states bracing for aurora viewings, this is an opportunity to bring communities together in appreciation of the skies. Yet, careful monitoring is essential, as geomagnetic storms can change quickly.

Astronomers remind us that the best shows are often the most unpredictable.
