US WARNS OF POWERFUL GEOMAGNETIC STORM FOLLOWING SOLAR ERUPTION

Wed 03 December 2025:

US space weather forecasters have issued a geomagnetic storm watch for December 3–4, warning of possible minor disruptions to power grids, satellite operations, and high-frequency communications.

The National Oceanic and Atmospheric Administration’s (NOAA) Space Weather Prediction Center classified the alert as a G2 level on Monday, meaning “moderate” storm conditions are expected.

The solar flare peaked at 9:49 p.m. EST on Sunday, November 30, said NASA’s Solar Dynamics Observatory, which constantly monitors the sun. The flare was classified as X1.9 flare, the space agency said. X-classes are the most intense kind of flare. The eruption came from a newly emerging sunspot region.

The flare briefly knocked out radio communications across Australia and parts of southeast Asia on Tuesday, Space.com reported.

A massive cloud of solar material called a coronal mass ejection, essentially an eruption from the Sun’s surface, was detected early Monday following a strong solar flare and peaked at 0249GMT, according to NASA.

It is now heading toward Earth and is expected to deliver “a glancing blow” to the Earth’s magnetic field on Wednesday and Thursday.

The storm could cause “mainly manageable effects to some technological infrastructure,” officials said.

This means satellite systems, mobile communications, GPS signals and radio waves might experience temporary disruptions, though major technical problems are rare at this level.

Parts of Australia and Southeast Asia experienced problems such as brief interruptions in radio communications on Tuesday, according to a report by Space.com.

The storm may also produce visible northern lights and colorful light displays in the sky across northern states from New York to Idaho and upper Midwest regions, the US agency said. These natural light shows, called auroras, typically only appear near the Arctic but can be seen farther south during geomagnetic storms.
