This was the most powerful flare measured with modern methods, classified as an X28. Our sun is an ever-changing and dynamic system, and NASA’s Solar Dynamics Observatory recently spotted the largest solar flare seen since … Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind.
For the first time since 20 Oct 2017, an M1 (R1-Minor) X-ray flare was observed from the Sun.

That was a solar maximum. During flares, a large amount of magnetic energy is released, heating the sun’s atmosphere and sending energized particles out into space. The sun's magnetic field is weak, allowing extra cosmic rays into the solar system. Cosmic Rays Solar minimum is underway.

Similar to the bulletins put out by the NWS local forecast offices, SWPC provides Alerts, Watches and Warnings to the public at large about what to expect from Space Weather. Solar storm warning: The Sun is entering a period of solar minimum right now (Image: NASA) And according to Dean Pesnell of NASA 's Goddard Space …

Solar flares are sometimes accompanied by a coronal mass ejection (CME for short). NASA's Solar Dynamics Observatory captured this imagery of a solar flare, as seen in the bright flash. The Solar and Heliospheric Observatory spacecraft captured this image of a solar flare as it erupted from the sun early on Nov 4, 2003. Image credit: NASA/SDO/Goddard.

Solar flares are powerful bursts of radiation. Solar flares are powerful bursts of radiation. An X-class solar flare, the biggest so far in 2015, erupted from the Sun last Wednesday, and NASA's Solar Dynamics Observatory has captured this incredible footage of the event.
On July 22-23, 2016, NASA’s Solar Dynamics Observatory observed three solar flares erupt in relatively quick succession. NASA's Solar Dynamics Observatory, which watches the sun constantly, captured images of the events. These bulletins are levels of severity of the solar activity that can be expected to impact the Earth’s environment. Potentially awakening from its cyclical 11-year slumber, a colossal solar flare just erupted from our Sun and was captured in all its cosmic brilliance by NASA's Solar Dynamics Observatory on May 29.

These pictures from NASA's Solar Dynamics Observatory show the three X-class flares that the sun emitted in under 24 hours on May 12-13, 2013.
