V sobotu 1.10.2011 narazila do Slunce kometa, kter\u00e1 svou velikost\u00ed nen\u00ed pr\u00e1v\u011b obvykl\u00e1 a hlavn\u011b zp\u016fsobila kolem na\u0161\u00ed hv\u011bzdy p\u011bkn\u00fd svin\u010d\u00edk. Co m\u016f\u017ee takov\u00e1 kometa, respektive n\u00e1sledek jej\u00ed sr\u00e1\u017eky se Sluncem zp\u016fsobit na zemi? Jak\u00fd dopad bude m\u00edt dopad siln\u00e9ho oblaku \u010d\u00e1stic koron\u00e1ln\u00ed hmoty, kter\u00fd v p\u0159\u00ed\u0161t\u00edch hodin\u00e1ch doraz\u00ed k Zemi?<\/strong><\/p>\n<\/div>\n

A hlavn\u011b, co je to vlastn\u011b koron\u00e1rn\u00ed hmota?<\/strong><\/p>\n

 <\/p>\n

RNDr. Anton\u00edn Svojtka prof. teoretick\u00e9 fyziky a kosmologie  – AV \u010cR – pro den\u00edk Popelky<\/strong><\/p>\n

Jde v z\u00e1sad\u011b o \u017ehav\u00e9 plyny a sm\u011bs siln\u011b nabit\u00fdch proton\u016f. Pozd\u011bji o oblak plazmatu, kter\u00fd je nabit energetick\u00fdmi \u010d\u00e1sticemi.<\/p>\n

 <\/p>\n

Ejekce koron\u00e1rn\u00ed hmoty, dok\u00e1\u017e\u00ed vypudit l\u00e1tku slune\u010dn\u00ed atmosf\u00e9ry asi tak v pom\u011bru jednoho trilionu kilogram\u016f. Takov\u00e9mu plazmatick\u00e9mu n\u00e1poru, se na\u0161e planeta um\u00ed do jist\u00e9 m\u00edry br\u00e1nit. Co\u017e je tak\u00e9 jedin\u00e9 \u0161t\u011bst\u00ed, proto\u017ee jinak by tady dlouho \u017eivot nebyl.<\/p>\n

 <\/p>\n

D\u00edky magnetick\u00e9mu poli je velk\u00e9 procento zachyceno a zemi tak neohroz\u00ed. <\/strong><\/p>\n

Pokud by ov\u0161em byla d\u00e1vka takov\u00e1, \u017ee by zem\u011b nebyla schopna svou ochrannou bari\u00e9rou pomoci, mohla by takov\u00e1 v\u011bc zp\u016fsobit rozs\u00e1hl\u00e9 \u0161kody.<\/p>\n

 <\/p>\n

P\u0159i takov\u00fdch mas\u00edvn\u00edch zm\u011bn\u00e1ch magnetick\u00e9ho pole, kter\u00e9 by patrn\u011b doprov\u00e1zela i velik\u00e1 pol\u00e1rn\u00ed z\u00e1\u0159e, se pak v rozvodn\u00fdch soustav\u00e1ch, podmo\u0159sk\u00fdch kabelech, telefonn\u00edch a t\u0159eba televizn\u00edch s\u00edt\u00edch indukuj\u00ed siln\u00e9 elektrick\u00e9 proudy, kter\u00e9 mohou po\u0161kodit \u010di zcela zni\u010dit nejr\u016fzn\u011bj\u0161\u00ed spot\u0159ebi\u010de.<\/p>\n

 <\/p>\n

Siln\u00e9 magnetick\u00e9 bou\u0159e prakticky v novodob\u00e9 historii moc zmapovan\u00e9 nem\u00e1me, jen sporadicky. <\/strong><\/p>\n

Jedna z nejv\u011bt\u0161\u00edch magnetick\u00fdch bou\u0159\u00ed v b\u0159eznu 1989 byla natolik intenzivn\u00ed, \u017ee prudk\u00e9 zm\u011bny geomagnetick\u00e9ho pole zp\u016fsobily t\u0159eba v Kanad\u011b po\u0161kozen\u00ed s\u00e9rie transform\u00e1tor\u016f a oblast s jedn\u00edm milionem lid\u00ed se na n\u011bkolik hodin ocitla ve tm\u011b.<\/p>\n

 <\/p>\n

Poruchy v ionosf\u00e9\u0159e pak zna\u010dn\u011b ru\u0161ily r\u00e1diov\u00e9 vys\u00edl\u00e1n\u00ed, a k \u010d\u00e1ste\u010dn\u00e9 ztr\u00e1t\u011b televizn\u00edho sign\u00e1lu. Kv\u016fli zv\u00fd\u0161en\u00e9 radiaci pak byla zm\u011bn\u011bna t trasa transatlantick\u00e9ho letadla Concorde.<\/p>\n

 <\/p>\n

Rychl\u00e9 elektrony pak mohou zamotat hlavu i v\u00fdpo\u010detn\u00ed technice. <\/strong><\/p>\n

\u010clov\u011bk se pak vlivem takov\u00fdch ud\u00e1lost\u00ed c\u00edtit, \u0159ekn\u011bme unaven\u011bj\u0161\u00ed a rozt\u011bkan\u011bj\u0161\u00ed. N\u011bkte\u0159\u00ed mohou poc\u00edtit bolesti hlavy, \u010di zm\u011bny tlaku.<\/p>\n

 <\/p>\n

Pokud by magnetick\u00e1 bou\u0159e byla siln\u00e1, a te\u010f se bav\u00edme akademicky, proto\u017ee nelze mluvit o p\u0159esn\u00e9m rozsahu v\u0161eho, co ochrannou vrstvou projde, a co ne, mohlo by pochopiteln\u011b takov\u00e9 nap\u011bt\u00ed zp\u016fsobovat \u0161kody \u00fam\u011brn\u011b rostouc\u00ed mno\u017estv\u00ed z\u00e1\u0159en\u00ed.<\/p>\n

 <\/p>\n

Pochopiteln\u011b, \u017ee n\u00e1raz velk\u00e9ho t\u011blesa m\u016f\u017ee ovlivnit i magnetickou stabilitu Slunce. <\/strong><\/p>\n

To by se neobe\u0161lo bez n\u00e1sledk\u016f, ov\u0161em o nich m\u016f\u017eeme klidn\u011b polemizovat. Na ka\u017ed\u00fd p\u00e1d by \u0161lo jen o teoretick\u00e9, jakkoli v\u011bdeck\u00e9 uva\u017eov\u00e1n\u00ed.<\/p>\n

 <\/p>\n

Takhle to vypad\u00e1, kdy\u017e kometa naraz\u00ed do Slunce.<\/strong><\/em><\/p>\n

<\/object> <\/strong><\/p>\n

M\u016f\u017eete vid\u011bt i onen v\u00fdron koron\u00e1rn\u00ed hmoty, jak o n\u011bm hovo\u0159il pan profesor.<\/strong><\/p>\n

 <\/p>\n

A my doufejme, \u017ee to co v dal\u0161\u00edch hodin\u00e1ch p\u0159ijde, nebude tak siln\u00e9. V p\u0159\u00edpad\u011b, \u017ee nep\u016fjdou po\u010d\u00edta\u010de, tak tedy p\u0159\u00edsah\u00e1m, \u017ee jsme vyd\u00e1n\u00ed \u010dtvrte\u010dn\u00edch Popelek vlo\u017eili poctiv\u011b. \"Wink\"<\/strong><\/p>\n
