Decembra s\u0101kumu ieskandin\u0101jis X klases uzliesmojums<\/p>\n
Decembris ies\u0101k\u0101s ar nopietnu notikumu kosmosa vid\u0113: jauna saules plankuma AR4299 rad\u012bts X1.9 klases Saules uzliesmojums izrais\u012bja iev\u0113rojamus radio trauc\u0113jumus. \u0160is sp\u0113c\u012bgais uzliesmojums uz laiku paralyz\u0113ja radio komunik\u0101ciju vis\u0101 Austr\u0101lij\u0101, k\u0101 ar\u012b sk\u0101ra da\u017eas Dienvidaustrumu \u0100zijas da\u013cas. Uzliesmojums sasniedza maksimumu aptuveni 9:49 p\u0113c ASV Austrumu laika 30. novembr\u012b (02:49 GMT 1. decembr\u012b), izce\u013coties no tikko redzam\u0101 re\u0123iona AR4299, kas atrad\u0101s Saules diska zieme\u013caustrumu mal\u0101.<\/p>\n
Uzliesmojums izrais\u012bja sp\u0113c\u012bgu R3 l\u012bme\u0146a radio absorbciju (radio blackout) uz Zemes apgaismot\u0101s puses spr\u0101dziena br\u012bd\u012b. X klases uzliesmojumi ir vissp\u0113c\u012bg\u0101kie zin\u0101mie Saules notikumi, kas desmitiem rei\u017eu p\u0101rsniedz M klases uzliesmojumus. \u0160\u0101diem notikumiem rakstur\u012bga intens\u012bva rentgena un ultraviolet\u0101 starojuma emisija, kas da\u017eu min\u016b\u0161u laik\u0101 sasniedz Zemi, joniz\u0113jot zem\u0101kos jonosf\u0113ras sl\u0101\u0146us. Tie\u0161i \u0161is process rada radio trauc\u0113jumus un \u012bslaic\u012bgus radiop\u0101rtraukumus uz Zemes dienas pus\u0113.<\/p>\n

Klasific\u0113jot notikumu k\u0101 R3 l\u012bme\u0146a trauc\u0113jumus, zin\u0101tnieki nor\u0101da, ka \u0161\u0101di notikumi sp\u0113j nopietni ietekm\u0113t sakarus, tostarp satel\u012btnavig\u0101ciju un avi\u0101cijas izmantot\u0101s augstfrekvences (HF) komunik\u0101cijas. Dati no SOHO (Solar and Heliospheric Observatory) koronogr\u0101fa att\u0113liem liecin\u0101ja par \u0101tru da\u013c\u0113ju halo formas koron\u0101l\u0101s masas izme\u0161anos (CME) \u2014 sp\u0113c\u012bgu plazmas un magn\u0113tisk\u0101 lauka izsvie\u0161anu no zieme\u013caustrumu robe\u017eas. Tom\u0113r model\u0113\u0161ana apstiprina, ka \u0161is CME nav v\u0113rsts uz Zemi.<\/p>\n
Uzman\u012bb\u0101 gigantiskais AR4294<\/p>\n
Galven\u0101 intriga pa\u0161laik saist\u012bta ar gigantisku saules plankumu, kas seko aiz notiku\u0161\u0101. Plankums AR4294 \u2014 mas\u012bvs un magn\u0113tiski sare\u017e\u0123\u012bts grupas komplekss \u2014 pa\u0161laik pagrie\u017eas Zemes virzien\u0101. Tas ir tik apjom\u012bgs un sare\u017e\u0123\u012bts, ka NOAA (Nacion\u0101l\u0101 oke\u0101nu un atmosf\u0113ras administr\u0101cija) bija spiesta to sadal\u012bt tr\u012bs atsevi\u0161\u0137\u0101s numur\u0113t\u0101s zon\u0101s. Tie\u0161i \u0161is re\u0123ions bija atbild\u012bgs par iepriek\u0161\u0113j\u0101 m\u0113nes\u012b nov\u0113rotajiem skait\u013ci\u0146ajiem X klases uzliesmojumiem, un kop\u0161 t\u0101 laika tas v\u0113l papla\u0161in\u0101jies.<\/p>\n
NOAA kosmosa laika prognoz\u0113t\u0101ji sagaida turpm\u0101kus M klases uzliesmojumus un nelielu iesp\u0113jam\u012bbu jauniem X klases uzliesmojumiem laika posm\u0101 no 1. l\u012bdz 3. decembrim. Lai gan pagaid\u0101m uz Zemes v\u0113rstu CME nav re\u0123istr\u0113ts, AR4294 aktivit\u0101tes pieaugums tuv\u0101kaj\u0101s dien\u0101s var main\u012bt situ\u0101ciju, t\u0101d\u0113\u013c tiek ieteikts sekot l\u012bdzi jaunumiem.<\/p>\n
