As early as January 2026, space scientists are warning us of a possible geomagnetic storm. The NOAA Space Weather Prediction Center has issued a storm warning for January 1-3, 2026, predicting that a coronal mass ejection (CME), a cloud of solar material, will impact Earth as late as January 2, 2026. This could cause a G2-severity geomagnetic storm, which is classified as “moderate” on the five-level NOAA scale.

Although it may result in beautiful auroras, there is also the potential for temporary disruptions in power grids and radio communications. Solar Storm Forecast According to official reports, NOAA’s Space Weather Prediction Center has issued G1-G2 geomagnetic storm watches for January 1-3, 2026. Forecast models indicate that a large cloud of solar plasma (a coronal mass ejection) will arrive late on January 2, possibly resulting in a G2 level storm by January 3.

According to NOAA’s classification, G2 is “moderate”, and such storms can briefly disrupt power grids and high-latitude radio communications. Potential Impact To put this in perspective, NOAA reports that the Sun is in the middle of its 11-year activity cycle and, thus, massive eruptions are common.

Even a moderate geomagnetic storm will temporarily affect satellite, navigation, and radio communications. There may be a bright full “Wolf Moon” on January 3 and any auroras that occur may be obscured. Scientists underline that these solar events help to focus attention on the fact that the Earth is exposed to solar activity and can gain direct experience to investigate Sun-Earth interactions.
