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.
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...
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.
Aug 9, 2011 · 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).
Jun 13, 2024 · Learn about the dark spots and bright explosions on the Sun's surface, and how they affect Earth. Find out how magnetic fields, solar activity, and coronal mass ejections work.
Learn how NASA tracked the most intense solar storm in decades, with 82 solar flares and multiple CMEs that created a G5 geomagnetic storm and brilliant auroras. See images, videos and citizen science reports of the historic event.
