How long are solar flares
Web28 feb. 2024 · Solar Flares. Solar flares happen because of the constantly moving magnetic fields in the Sun's atmosphere. As the Sun approaches solar maximum (the most active part of its 11-year cycle), its magnetic fields become more and more complex. The magnetic fields loop around, and cross over each other, cutting each other off, and … WebThe frequency of flares coincides with the Sun's eleven year cycle. When the solar cycle is at a minimum, active regions are small and rare and few solar flares are detected. …

WebA solar flare isn't just an explosion of hot gases. It pushes out waves of light all across the spectrum. That includes light we can't see -- including radiation in the form of X-rays and gamma rays. These rays can be dangerous to humans. Fortunately, the Earth's atmosphere absorbs most of these high-energy rays. WebSolar ejections are often associated with flares and sometimes occur shortly after the flare explosion. Coronal mass ejections are clouds of electrified, magnetic gas weighing billions of tons ejected from the Sun …

WebThe solar winds reach a speed of about 400 km/s and take around three days to reach Earth. There are areas on the sun where the solar magnetic field extends into space. From these areas, the solar winds can be ejected with considerably more mass at speeds of up to three million km/s. WebA solar flare is a tremendous explosion on the Sun that happens when energy stored in 'twisted' magnetic fields (usually above sunspots) is suddenly released. In a matter of …
