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...
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.
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).
Learn how solar flares, large eruptions of electromagnetic radiation from the Sun, can cause radio blackouts by ionizing the lower layers of the ionosphere. Find out the classification, intensity, and impact of solar flares and radio blackouts on HF radio communication.
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.
A solar flare is a tremendous explosion on the Sun that happens when energy stored in 'twisted' magnetic fields (usually above sunspots) is suddenly released.
