A erupted with M1 and M6 class solar flares. Watch the fireworks in these views from NASA's Solar Dynamics Observatory.

The sun started 2025 with a bang as it fired off a powerful solar flare this morning. The X-class solar flare peaked at an X1.2 at 6:40 a.m. EST (1140 GMT) on Friday (Jan. 3), releasing a blast of ...

12 at 6:40 a.m. EST (1140 GMT) on Friday (Jan. 3), releasing a blast of energy from a sunspot region known as AR 3947 and triggering a radio blackout event for parts of the Southern Atlantic ...

These stellar explosions can send waves of radiation toward Earth that trigger temporary radio blackouts. The flares can also unleash fast-moving clouds of magnetized plasma, known as coronal mass ...

A solar explosion called a coronal mass ejection is poised to graze Earth on Friday or Saturday (Jan. 24 or Jan. 25), potentially triggering colorful auroras over the northern U.S. A powerful ...

disrupting high-frequency radio signals and causing radio blackouts—and they can also damage spacecraft electronics, reduce the accuracy of GPS signals, induce dangerous currents in power grids ...

Minor-to-moderate radio blackouts due to solar flare activity are also likely through Sunday, according to the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center.

The impact could trigger a minor G1-class geomagnetic storm — a temporary disruption to Earth's magnetic field that can result in radio blackouts, power grid fluctuations, satellite malfunctions ...

Multiple states saw the multi-colored light show from a severe storm on New Year’s Eve and Day. Minor-to-moderate radio blackouts due to solar flare activity are also likely through Sunday, according ...
