Powerful Solar Flare Causes Radio Blackouts Over Pacific
A powerful X1.2-class solar flare erupted from sunspot region 4114, causing radio blackouts over the Pacific Ocean, including Hawaii, without accompanying a coronal mass ejection. The flare's electromagnetic energy disrupted radio signals and indicates potential for further solar activity that could impact Earth, such as geomagnetic storms and auroras.
Sun unleashes powerful X-class solar flare, threatens space weather havoc.
The sun emitted a strong solar flare classified as an X1.2 flare on March 28, 2023, which was captured by NASA's Solar Dynamics Observatory. Solar flares and eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts. NASA constantly observes the sun and our space environment with a fleet of spacecraft to study everything from the sun's activity to the solar atmosphere and magnetic fields in the space surrounding Earth.
