Mar 28, 2025 · The Sun emitted a strong solar flare, peaking at 11:21 a.m. ET on Friday, March 28. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.. NASA’s Solar Dynamics Observatory captured this image of a solar flare — seen as the bright flash on the left side of the Sun — on March 28.

What are solar flares? What is a Coronal Mass Ejection (CME)? The plot on this page shows us the most recent 24-hour solar X-ray data from the primary GOES satellite.

Mar 31, 2025 · Solar flares are classified on a scale of A, B, C, M, and X. Each class is 10 times more powerful than the last, with X-class flares being the most powerful and least frequent.

A solar flare is a relatively intense, localized emission of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other eruptive solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle.

Jan 6, 2025 · The Sun emitted a strong solar flare, peaking at 7:48 a.m. ET on Jan. 4, 2025. The National Oceanic and Atmospheric Administration’s Solar Ultraviolet Imager, which watches the Sun constantly, captured an image of the event. Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation …

Jul 6, 2022 · Solar flares are large explosions from the surface of the sun that emit intense bursts of electromagnetic radiation. The intensity of the explosion determines what classification the flare...

Nov 2, 2024 · Solar Flares. A solar flare is an intense burst of radiation, or light, on the Sun. These flashes span the electromagnetic spectrum — including X-rays, gamma rays, radio waves, and ultraviolet and visible light. Solar flares are the most powerful explosions in the solar system — the biggest ones can have as much energy as a billion hydrogen ...

Oct 24, 2024 · Solar flares are explosive events on the sun's surface that emit strong bursts of electromagnetic radiation. These flares occur when magnetic energy accumulates in the solar atmosphere and is...

Jan 10, 2025 · On Oct. 3, 2024, an X9 magnitude solar flare — the most powerful of the current cycle — erupted from the sun, launching a CME directly at Earth. (Image credit: NASA/SDO) The effects of the...

Mar 13, 2025 · Solar flare, sudden intense brightening in the solar corona, usually in the vicinity of a magnetic inversion near a sunspot group. The flare develops in a few minutes, or even seconds, and may last several hours.
