An active region of the Sun, known as sunspot 4114, has just produced an X1.9-class flare. This event, which occurred on June 19, had an impact on Earth and our communications. X-class solar flares ...

A powerful X-class solar flare erupted on June 19, disrupting radio signals and potentially setting the stage for geomagnetic storms and rare aurora sightings.

Solar flares can affect us on Earth, and radiation from this flare caused a shortwave radio blackout. A map released by the ...

The M-class flare was accompanied by a coronal mass ejection currently forecast to land Earth with a glancing blow on June 18.

It was an X-class flare — the most intense kind, NASA said. Solar flares are essentially "giant explosions on the sun" that send energy, light and high-speed particles into space, according to NASA.

Another X-class solar flare triggers US communication blackouts as the sun continues to emit intense solar flares during the solar maximum.

What is an X-class solar flare detected by NASA Solar flares are powerful bursts of radiation from the Sun, and X-class flares are the strongest among them.
