  2. Sudden ionospheric disturbance - Wikipedia

    en.wikipedia.org/wiki/Sudden_ionospheric_disturbance

    When a solar flare occurs on the Sun a blast of intense ultraviolet (UV) and x-ray (sometimes even gamma ray) radiation hits the dayside of the Earth after a propagation time of about 8 minutes. This high energy radiation is absorbed by atmospheric particles, raising them to excited states and knocking electrons free in the process of ...

  3. Solar flare - Wikipedia

    en.wikipedia.org/wiki/Solar_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.

  4. Space sunshade - Wikipedia

    en.wikipedia.org/wiki/Space_sunshade

    By using the solar radiation pressure on the mirrors as solar sails and tilting them in the right direction, the flyer will be capable of altering its speed and direction to keep in position. [ 12 ] Such a group of sunshades would need to occupy an area of about 3.8 million square kilometers if placed at the L1 point [ 12 ] (see other lower ...

  5. Solar storm - Wikipedia

    en.wikipedia.org/wiki/Solar_storm

    Solar storms include: Solar flare, a large explosion in the Sun's atmosphere caused by tangling, crossing or reorganizing of magnetic field lines; Coronal mass ejection (CME), a massive burst of plasma from the Sun, sometimes associated with solar flares; Geomagnetic storm, the interaction of the Sun's outburst with Earth's magnetic field

  6. Ionospheric storm - Wikipedia

    en.wikipedia.org/wiki/Ionospheric_storm

    The radiation emitted by solar wind only reaches the highest layers of the Earth's atmosphere, including the ionosphere. There are however reports of a possible impact on lower layers of the atmosphere. It is recorded that the increase of solar wind during March 2012 in the United States coincided with the heat waves that occurred at the time. [29]

  7. Radiation protection - Wikipedia

    en.wikipedia.org/wiki/Radiation_protection

    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]

  9. Solar radio emission - Wikipedia

    en.wikipedia.org/wiki/Solar_radio_emission

    Coherent mechanisms can produce much larger brightness temperatures (intensities) and are primarily responsible for the intense spikes of radiation called solar radio bursts, which are byproducts of the same processes that lead to other forms of solar activity like solar flares and coronal mass ejections.
