I-aurora australis ibonakala kusuka kumaphi amazwe?
Context:I-aurora (pl: auroras noma i-aurorae),[b] eyaziwa nangokuthi izibani ze-polar, [c] ukubonakaliswa kokukhanya kwemvelo esibhakabhakeni somhlaba, okubonakala kakhulu ezifundeni ezinobubanzi obuphakeme (ezungeze i-Arctic ne-Antarctic). Ama-aurora abonisa imiklamo enamandla yokukhanya okukhazimulayo okubonakala njengamakhethini, imisebe, imicu, noma ukubaneka okunamandla okuhlanganisa isibhakabhaka sonke. Ama - aurora abangelwa ukuphazamiseka kwe - magnetosphere okubangelwa umoya welanga. Ukuphazamiseka okukhulu kubangelwa ukuthuthuka kwejubane lomoya welanga ovela emigodini ye-coronal nasekukhishweni kobuningi be-coronal. Lezi ziphazamiso zishintsha indlela izinhlayiya ezikhokhelwayo ezihamba ngayo ku-plasma ye-magnetosphere. Lezi zinhlayiya, ikakhulukazi ama-electron nama-proton, ziwela emkhathini ongaphezulu (i-thermosphere/exosphere). Ukwakheka kwe - ion nokukhuthazwa kwezakhi zomkhathi kukhipha ukukhanya okunezinhlobonhlobo zombala nokuyinkimbinkimbi. Ukwakheka kwe-aurora, okwenzeka ngaphakathi kwamabhande azungeze izifunda zombili ze-polar, nakho kuncike ebuningini bokusheshisa okunikezwe izinhlayiya ezikhishwayo. Ezingxenyeni ezisenyakatho, lo mphumela waziwa ngokuthi i-aurora borealis noma izibani zasenyakatho. Igama lokuqala laqanjwa nguGalileo ngo-1619, lisuselwa kunkulunkulukazi waseRoma wokusa kanye negama lesiGreki lomoya wasenyakatho. Umlingani waseningizimu, i-aurora australis noma izibani zaseningizimu, unezici ezicishe zifane ne-aurora borealis futhi ziguquka ngasikhathi sinye nezinguquko endaweni esenyakatho ye-auroral. I-aurora australis ibonakala kusuka ezindaweni eziphakeme zaseningizimu e-Antarctica, eChile, e-Argentina, eNingizimu Afrika, eNew Zealand nase-Australia. I-aurora borealis ibonakala ezindaweni ezizungeze i-Arctic njenge-Alaska, izindawo zaseCanada, i-Iceland, iGreenland, iNorway, iSweden, iFinland neSiberia. Ezimweni ezingavamile i-aurora borealis ingabonakala eningizimu yeMedithera nasezifundazweni eziseningizimu ye-United States.
