Northern Lights may illuminate skies over northern US during Thanksgiving weekend geomagnetic storm

The Northern Lights may grace the skies over parts of the northern U.S. this Thanksgiving weekend due to a geomagnetic storm. The National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center (SWPC) has issued a G1 (minor) Geomagnetic Storm Watch for Thursday and a G2 (moderate) watch for Friday, following a coronal mass ejection (CME) observed on Monday.

As charged particles from the CME interact with Earth’s magnetic field, auroras could be visible in northern states, including Maine and northern Michigan, as well as the Upper Midwest. However, viewing opportunities might be hindered by widespread cloud cover caused by a coast-to-coast winter storm bringing snow and rain.

The SWPC notes that geomagnetic storms, while visually spectacular, can affect critical infrastructure. Under moderate storm conditions, power grids may experience fluctuations, and satellites in low-Earth orbit could face increased drag. Communication systems and GPS navigation may also be disrupted.

Alaska, Washington, and other high-latitude regions typically have the best chance for aurora sightings. The SWPC emphasizes that the visibility of the Northern Lights depends on local weather and clear skies.

In addition to the natural light show, NOAA and other agencies monitor solar activity to predict and mitigate potential impacts on Earth’s systems. Experts recommend avoiding urban light pollution and heading to rural areas for the best chance to see the auroras.

While the storm provides a rare opportunity for skywatchers, its effects on daily life serve as a reminder of the Sun's influence on Earth. As the weekend approaches, both science enthusiasts and travelers are advised to plan accordingly, considering weather conditions and possible disruptions.
