  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. 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

  5. Did a solar flare cause the AT&T outage? Here's what we know

    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 ...

  6. Solar particle event - Wikipedia

    en.wikipedia.org/wiki/Solar_particle_event

    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 ...

  7. 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.

  8. 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]
