Suid-Afrika het onlangs een van die merkwaardigste natuurverskynsels beleef \u2013 die aurora australis<\/i>, en dit het groot opwinding by die publiek veroorsaak. Hierdie skaars vertoning het mense in verskeie dele van die land na die naghemel laat opkyk, terwyl die ruimte se skouspelagtige ligte sigbaar was. Maar wat presies het hierdie verskynsel veroorsaak?<\/p>\n
\n Wat is \u2019n sonstorm?<\/b>\n<\/p>\n
\u2019n Sonstorm gebeur wanneer die son, ons vurige reus in die ruimte, reuse-ontploffings vol energie uitstuur. Hierdie energie beweeg deur die ruimte en kan die aarde tref. Wanneer dit gebeur, kan dit nie net pragtige ligverskynsels, soos auroras, veroorsaak nie, maar ook \u2019n invloed h\u00ea op elektrisiteit, GPS- en selfs radioseine.<\/p>\n
\n Wat het in Suid-Afrika gebeur?<\/b>\n<\/p>\n
Mense het onlangs in sekere dele van Suid-Afrika vreemde, flikkerende ligte in die lug opgemerk. Hierdie ligte staan bekend as die Aurora Australis<\/span>, of die Suiderligte, en word gewoonlik naby Antarktika waargeneem. Mense in die suidelike streke van Suid-Afrika, insluitend die Wes-Kaap, het di\u00e9 seldsame vertoning danksy \u2019n kragtige sonstorm beleef.<\/p>\n Benewens die pragtige ligte het sommige gebiede ook kragonderbrekings ervaar, en daar was selfs berigte van versteurde satellietkommunikasie. Hoewel dit nie lank aangehou het nie, was dit genoeg om die publiek aan die praat te kry.<\/p>\n \n Hoekom het dit gebeur?<\/b>\n<\/p>\n Die son borrel voortdurend energie. Soms gebeur \u2019n uitbarsting, en dit stuur sogenaamde sonwind die ruimte in. Hierdie sonwind bestaan uit gelaaide deel\u00adtjies wat teen ho\u00eb spoed beweeg. <\/p>\n Wanneer hierdie deeltjies die aarde bereik, bots hulle met die planeet se magnetiese veld, en d\u00edt is wanneer dinge interessant raak.<\/p>\n Di\u00e9 keer was die sonwind besonder sterk, wat ver\u00adklaar waarom Suid-Afrika die uitwerking daarvan ervaar het. Hoewel sulke storms nie gewoonlik groot proble\u00adme veroorsaak nie, kan dit ligverskynsels soos auroras in gebiede sigbaar maak waar dit gewoonlik nie gesien word nie.<\/p>\n Suid-Afrikaners sal seker nog lank praat oor hierdie onverwagte en wonderlike vertoning in die naghemel.<\/p>\n","protected":false},"excerpt":{"rendered":" Suid-Afrika het onlangs een van die merkwaardigste natuurverskynsels beleef \u2013 die aurora australis, en dit het groot opwinding by die publiek veroorsaak.
