Sp\u0113c\u012bga saules uzliesmojuma sekas: radio sakari Austr\u0101lij\u0101 p\u0101rtraukti<\/p>\n
Decembris ies\u0101k\u0101s ar dabas iev\u0113rojamu notikumu \u2013 sp\u0113c\u012bga X1.9 klases saules uzliesmojuma d\u0113\u013c, kas rad\u0101s no jauna saules plankuma AR4299, vis\u0101 Austr\u0101lij\u0101 tika b\u016btiski trauc\u0113ti radio sakari. \u0160is notikums neap\u0161aub\u0101mi rad\u012bja galvass\u0101pes ne tikai tiem, kas j\u016bt\u012bgi pret laikapst\u0101k\u013cu izmai\u0146\u0101m, bet ar\u012b sa\u0161\u0137ob\u012bja glob\u0101l\u0101s sakaru sist\u0113mas, \u012bpa\u0161i Dienvidaustrum\u0101zijas da\u013c\u0101.<\/p>\n
Uzliesmojuma maksimums tika re\u0123istr\u0113ts 30. novembr\u012b aptuveni 9:49 p\u0113c ASV austrumu laika (1. decembr\u012b plkst. 02:49 p\u0113c GMT). Tas rad\u0101s jaun\u0101 saules plankum\u0101 AR429, tikko tam par\u0101doties virs Saules zieme\u013caustrumu malas. \u0160\u012b spo\u017e\u0101 ener\u0123ijas izpl\u016bduma rezult\u0101t\u0101 uz Zemes apgaismot\u0101s puses tika rad\u012bts sp\u0113c\u012bgs, R3 l\u012bme\u0146a radio aptumsums.<\/p>\n
Saules uzliesmojumu sp\u0113ks un ietekme<\/p>\n
X klases saules uzliesmojumi ir starp vissp\u0113c\u012bg\u0101kajiem zin\u0101majiem ener\u0123ijas izvirdumiem, radot intens\u012bvu rentgena un ultravioleto starojumu, kas Zemi sasniedz vien da\u017eu min\u016b\u0161u laik\u0101. \u0160\u012b starojuma ietekm\u0113 joniz\u0113jas Zemes atmosf\u0113ras apak\u0161\u0113jie sl\u0101\u0146i, radot radio trauc\u0113jumus un piln\u012bgus “radio aptumsumus” uz plan\u0113tas dienas pusi. K\u0101 liecina klasifik\u0101cija, R3 l\u012bme\u0146a notikumi ir sp\u0113j\u012bgi nopietni trauc\u0113t sakarus, satel\u012btu navig\u0101ciju un HF (augstfrekvences) sakarus, ko izmanto avi\u0101cija. Lai saprastu \u0161\u012bs par\u0101d\u012bbas m\u0113rogu, varam sal\u012bdzin\u0101t \u2013 X klases uzliesmojumi ir desmitiem rei\u017eu sp\u0113c\u012bg\u0101ki nek\u0101 M klases uzliesmojumi.<\/p>\n
Papildu draudi no gigantisk\u0101 saules plankuma<\/p>\n
Saska\u0146\u0101 ar datiem no SOHO (Solar and Heliospheric Observatory) koronaogr\u0101fa att\u0113liem, notikums bija saist\u012bts ar \u0101tru, da\u013c\u0113ji halo veida koronas masas izme\u0161anu (CME) \u2013 jaud\u012bgu saules plazmas un magn\u0113tisk\u0101 lauka izmestuvi, kas izvirz\u012bj\u0101s no zieme\u013caustrumu malas. Lai gan model\u0113\u0161ana liecina, ka \u0161is CME nav v\u0113rsts tie\u0161i uz Zemi, \u012bst\u0101 intriga sl\u0113pjas aiz t\u0101 uzrau\u0161an\u0101s gigantiskaj\u0101 saules plankum\u0101 AR4294. \u0160is milz\u012bgais un magn\u0113tiski sare\u017e\u0123\u012btais plankumu kopums ir pav\u0113rsies m\u016bsu plan\u0113tas virzien\u0101. T\u0101 izm\u0113rs un sare\u017e\u0123\u012bt\u012bba ir tik liela, ka NOAA bija spiesta sadal\u012bt to tr\u012bs numur\u0113t\u0101s zon\u0101s. Tie\u0161i \u0161is Saules re\u0123ions iepriek\u0161\u0113j\u0101 m\u0113nes\u012b bija atbild\u012bgs par vair\u0101kiem X klases uzliesmojumiem, un kop\u0161 t\u0101 laika tas ir tikai palielin\u0101jies.<\/p>\n
Prognozes un v\u0113sturiski piem\u0113ri<\/p>\n
Kosmisk\u0101 laikapst\u0101k\u013cu prognoz\u0113t\u0101ji no NOAA sagaida turpm\u0101kus M klases uzliesmojumus un nelielu iesp\u0113jam\u012bbu jauniem X klases uzliesmojumiem laik\u0101 no 1. l\u012bdz 3. decembrim. Lai gan pagaid\u0101m nav fiks\u0113ti uz Zemi v\u0113rsti CME, AR4294 pieaugo\u0161\u0101 aktivit\u0101te var main\u012bt situ\u0101ciju tuv\u0101kaj\u0101s dien\u0101s. Tikm\u0113r \u0123eomagn\u0113tiskie apst\u0101k\u013ci paredzami paliks galvenok\u0101rt mier\u012bgi l\u012bdz 3. decembrim, kad koron\u0101l\u0101s dobuma pl\u016bsma ar negat\u012bvu polarit\u0101ti var izrais\u012bt nelielu G1 l\u012bme\u0146a \u0123eomagn\u0113tisko v\u0113tru.<\/p>\n
\u0160\u0101di sp\u0113c\u012bgi saules notikumi jau iepriek\u0161 ir rad\u012bju\u0161i iev\u0113rojamas sekas. Piem\u0113ram, “Bastille Day” saules v\u0113tru laik\u0101 2000. gada j\u016blij\u0101 X5.7 klases uzliesmojums un tam sekojo\u0161ais CME izrais\u012bja sp\u0113c\u012bgu \u0123eomagn\u0113tisko v\u0113tru, kas trauc\u0113ja satel\u012btu un radio sakarus. Savuk\u0101rt 2003. gada “Halloween” v\u0113tru s\u0113rija izrais\u012bja tehniskus trauc\u0113jumus glob\u0101laj\u0101s navig\u0101cijas sist\u0113m\u0101s, vair\u0101ku satel\u012btu boj\u0101jumus un lok\u0101lus elektroener\u0123ijas t\u012bklu atsl\u0113gumus. Pirms pusotra gada notika v\u0113l viens jaud\u012bgs uzliesmojums, un 2023. gad\u0101 tika nov\u0113rots viens no vissp\u0113c\u012bg\u0101kajiem uzliesmojumiem nov\u0113rojumu v\u0113stur\u0113.
