Editing Cosmic noise (section)

=== Solar wind ===
[[Solar wind]] is a flux of particles, [[proton]]s and [[electron]]s together with [[Atomic nucleus|nuclei]] of heavier elements in smaller numbers, that are accelerated by the high temperatures of the [[solar corona]] to velocities large enough to allow them to escape from the Sun's gravitational field.<ref>{{Cite web |title=Solar wind |url=https://www.britannica.com/science/solar-wind |access-date=2021-04-09 |website=Encyclopedia Britannica |language=en}}</ref>

Solar wind causes sudden bursts of cosmic noise absorption in the Earth's ionosphere. These bursts can only be detected only if the magnitude of the geomagnetic field perturbation caused by the solar wind shock is large enough.<ref>{{cite journal |last1=Osepian |first1=A. |last2=Kirkwood |first2=S. |title=Cosmic radio-noise absorption bursts caused by solar wind shocks |journal=Annales Geophysicae |date=7 September 2004 |volume=22 |issue=8 |pages=2973–2987 |doi=10.5194/angeo-22-2973-2004 |bibcode=2004AnGeo..22.2973O |s2cid=55842333 |url=https://angeo.copernicus.org/articles/22/2973/2004/angeo-22-2973-2004.pdf |archive-url=https://web.archive.org/web/20200921072326/https://angeo.copernicus.org/articles/22/2973/2004/angeo-22-2973-2004.pdf |archive-date=2020-09-21 |url-status=live |access-date=9 November 2022 |language=en |doi-access=free }}</ref>
