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.
Post-eruptive loops in the wake of a solar flare, image taken by the TRACE satellite (photo by NASA). In solar physics, a solar particle event (SPE), also known as a solar energetic particle event or solar radiation storm, [a] [1] is a solar phenomenon which occurs when particles emitted by the Sun, mostly protons, become accelerated either in the Sun's atmosphere during a solar flare or in ...
Radiation protection, also known as radiological protection, is defined by the International Atomic Energy Agency (IAEA) as "The protection of people from harmful effects of exposure to ionizing radiation, and the means for achieving this". [1]
Our life-giving death star is experiencing its "solar maximum," which sounds like the name of a Christian rock band and is defined as the peak activity period within the sun's 11-year solar cycle.
They are broad-band continuum emissions associated either with solar flares or Type I bursts. [16] Flare-associated Type IV bursts are also called flare continuum bursts, and they typically begin at or shortly after a flare's impulsive phase. Larger flares often include a storm continuum phase that follows after the flare continuum. [89]
A solar flare is an intense burst of radiation associated with sunspots that releases magnetic energy out into space, according to NASA. These giant explosions from the sun send energy, light, and ...
Solar energetic particles (SEP) accelerated by coronal mass ejections or solar flares can trigger solar particle events, a critical driver of human impact space weather, as they can damage electronics onboard spacecraft (e.g. Galaxy 15 failure), and threaten the lives of astronauts, as well as increase radiation hazards to high-altitude, high ...
The geomagnetic storm causing this event is believed to be the result of two separate events known as coronal mass ejections (CME) on March 10 and 12, 1989. [2] A few days before, on March 6, a very large X15-class solar flare also occurred. [3]
