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.
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.
From May 3 through May 9, 2024, NASA’s Solar Dynamics Observatory observed 82 notable solar flares. The flares came mainly from two active regions on the Sun called AR 13663 and AR 13664. This video highlights all flares classified at M5 or higher with nine categorized as X-class solar flares.
Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs).
Jul 16, 2024 · Solar flares are powerful blasts of electromagnetic radiation that explode outward from sunspots on the sun's surface when pent-up magnetic energy in the solar atmosphere is...
Solar flares are large eruptions of electromagnetic radiation from the Sun lasting from minutes to hours. The sudden outburst of electromagnetic energy travels at the speed of light, therefore any effect upon the sunlit side of Earth’s exposed outer atmosphere occurs at the same time the event is observed.
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...
Jul 9, 2024 · Solar flares and CMEs are the most powerful explosions in our solar system. This animation shows how coronal mass ejections can blow out from the Sun, interfere with Earth’s magnetic fields (the curved purple lines), and cause auroras (the blue rings of light circling the North and South poles).
May 14, 2024 · A solar flare is an intense burst of radiation, or light, on the Sun. Flares are our solar system’s most powerful explosive events. Light only takes about 8 minutes to travel from the Sun to Earth, so that’s how long it would take the energy from a flare to reach our planet.
Mar 30, 2022 · Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts. This flare is classified as an X-Class flare.
