https://www.universomagico.net/2024/05/erupcion-solar-x39.html

The Sun emitted a strong solar flare, which peaked at 6:54 am UT on May 10, 2024. The Solar Dynamics Observatory, which observes the Sun constantly, captured an image of this event, as seen in the bright flash towards the center of the image. Solar flares are powerful explosions of energy that can affect radio communications, electrical power grids, navigation signals and.....
