Expect more geomagnetic storms today (Monday) as the sun continues to unleash X-class flares, CBS News reported.

The recent strongest geomagnetic storm in over two decades hit Earth on Friday, causing radio blackouts and stunning auroras visible even in the southern U.S. But the stormy weather isn’t over yet, officials caution.

Geomagnetic storms expected on Monday: Forecast and outlook from NOAA

According to NOAA’s Space Weather Prediction Center, a G3, or “strong,” geomagnetic storm warning remains in place until 2 a.m. ET Monday.

While the likelihood of stronger storms has diminished, conditions are anticipated to calm throughout the day gradually. However, moderate to strong geomagnetic storms are still expected on Monday, with minor storms possible on Tuesday.

“Flares of this magnitude are not frequent,” the center said. “…Users of high frequency (HF) radio signals may experience temporary degradation or complete loss of signal on much of the sunlit side of Earth.”

As another X-class solar flare was detected, the update highlights ongoing solar activity. X-class flares represent the most powerful category of these solar eruptions, with the latest one categorized as “moderate.”

Moreover, the center forecasts that solar activity will remain at high levels, raising the possibility of additional solar flares, characterized by bursts of electromagnetic radiation emitted from the sun.

Intense solar activity from Sunspot Region 3664

Sunday saw a powerful X-class flare, potentially causing hour-long radio blackouts on the sunlit side of Earth. Originating from Sunspot Region 3664, known for its frequent flares and CMEs, it contributed to the recent extreme geomagnetic storm. NOAA labeled this region as the most active on the sun’s surface.

Region 3664, visible to the naked eye with eclipse glasses, spans 124,000 miles. Accompanied by Region 3663, forming a magnetically complex area larger than Earth, it underscores ongoing solar activity.

CMEs, characterized by large bursts of plasma and magnetic fields from the sun’s atmosphere, which trigger geomagnetic storms, are forecasted to persist throughout Monday, sustaining G3 activity.

NOAA predicts that the ongoing but diminishing influence of CMEs will gradually lessen responses to unsettled G1 (Minor) levels by May 14th. Solar radiation storms are also anticipated during the same timeframe. Some of the radio blackouts could be classified as “strong” events depending on the intensity of the solar flares that occur.
