  2. 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 ...

  3. Geomagnetic storm - Wikipedia

    en.wikipedia.org/wiki/Geomagnetic_storm

    A geomagnetic storm, also known as a magnetic storm, is a temporary disturbance of the Earth's magnetosphere caused by a solar wind shock wave. The disturbance that drives the magnetic storm may be a solar coronal mass ejection (CME) or (much less severely) a corotating interaction region (CIR), a high-speed stream of solar wind originating ...

    en.wikipedia.org/wiki/Solar_activity_and_climate

    The finding that solar activity was approximately the same in cycles 14 and 24 applies to all solar outputs that have, in the past, been proposed as a potential cause of terrestrial climate change and includes total solar irradiance, cosmic ray fluxes, spectral UV irradiance, solar wind speed and/or density, heliospheric magnetic field and its ...

    The solar storm could pose a minimal threat to things like satellites, GPS signals and power grids, but it may also provide some additional Thanksgiving entertainment when football and the Macy's ...

  9. Solar radio emission - Wikipedia

    en.wikipedia.org/wiki/Solar_radio_emission

    A propagation effect is anything that impacts the path or state of an electromagnetic wave after it is produced. These effects therefore depend on whatever mediums the wave passed through before being observed. The most dramatic impacts to solar radio emission occur in the corona and in Earth's ionosphere. There are three primary effects ...
