B\u00e1jn\u00e9 sk\u0159\u00edtky nalezneme snad po cel\u00e9m sv\u011bt\u011b. \u010casto kutaj\u00ed v hor\u00e1ch rudu, tu a tam vylezou na zemsk\u00fd povrch a \u0161kod\u00ed nebo pom\u00e1haj\u00ed. To asi podle n\u00e1tury. Podle legendy je nalezneme i v nitru hory Kriv\u00e1\u0148 ve Vysok\u00fdch Tatr\u00e1ch. Ov\u0161em, ob\u010das se objev\u00ed i nad horami.<\/h6>\n

\"\"Sk\u0159\u00edtci, na kter\u00e9 se dnes zam\u011b\u0159\u00edme, se objevili v \u010dervnu nad Tatrami. A nevylezli z nitra Kriv\u00e1n\u011b, ale p\u0159i\u0161li t\u00e9m\u011b\u0159 z nebe. Konkr\u00e9tn\u011b z bou\u0159kov\u00fdch oblak\u016f, kter\u00e9 se nach\u00e1zely asi 250 kilometr\u016f od fotografa Daniela \u0160\u010derby. Ten zaznamenal vz\u00e1cn\u00fd jev takzvan\u00fdch \u201erud\u00fdch sk\u0159\u00edtk\u016f\u201c v neuv\u011b\u0159iteln\u00e9 kvalit\u011b. Druh\u00fdm z tandemu autor\u016f je matematick\u00fd specialista Miloslav Druckm\u00fcller, kter\u00fd data zpracoval do t\u00e9m\u011b\u0159 neuv\u011b\u0159iteln\u00e9 podoby.<\/p>\n

Tito sk\u0159\u00edtci byli sice poprv\u00e9 pops\u00e1ni n\u011bmeck\u00fdm historikem a pr\u00e1vn\u00edkem Johannem Georgem Estorem v roce 1730, tato informace v\u0161ak nadlouho zapadla, stejn\u011b jako jejich pozorov\u00e1n\u00ed v roce 1956 laure\u00e1tem Nobelovy ceny a skotsk\u00fdm fyzikem Charlesem Wilsonem, autorem teorie elektrick\u00fdch poruch v horn\u00ed atmosf\u00e9\u0159e. Prvn\u00ed v\u011bdecky potvrzen\u00e9 pozorov\u00e1n\u00ed bylo uskute\u010dn\u011bno 6. \u010dervence 1989 v\u011bdci z Univerzity v Minnesot\u011b. Od t\u00e9 doby bylo mnoho t\u011bchto jev\u016f zaznamen\u00e1no pozorov\u00e1n\u00edm z letadla, ze zem\u011b a dokonce i z vesm\u00edru.<\/p>\n

Jedn\u00e1 se vlastn\u011b o kr\u00e1tkodob\u00e9 elektrick\u00e9 v\u00fdboje, nadobla\u010dn\u00e9 blesky p\u0159ev\u00e1\u017en\u011b \u010derven\u00e9 barvy, kter\u00e9 pro svou nepolapitelnost byly nazv\u00e1ny \u201erud\u00fdmi sk\u0159\u00edtky\u201c. Vznikaj\u00ed jako rozs\u00e1hl\u00fd elektrick\u00fd v\u00fdboj nad bou\u0159kov\u00fdmi mraky siln\u00fdch bou\u0159\u00ed. Vyskytuj\u00ed se p\u0159ev\u00e1\u017en\u011b ve v\u00fd\u0161k\u00e1ch 50 a\u017e 90 kilometr\u016f nad zem\u00ed a jejich barva je zp\u016fsobena p\u0159echodem elektronu mezi prvn\u00edm a druh\u00fdm excitovan\u00fdm stavem atomu dus\u00edku. Existuj\u00ed i pozorov\u00e1n\u00ed modr\u00e9 barvy zp\u016fsoben\u00e9 sice p\u0159echody elektron\u016f tak\u00e9 v atomu dus\u00edku, ov\u0161em mezi druhou a t\u0159et\u00ed hladinou.<\/p>\n

Dle podrobn\u00fdch pozorov\u00e1n\u00ed se ukazuje, \u017ee se jedn\u00e1 o shluk ionizovan\u00fdch koul\u00ed o pr\u016fm\u011bru 10 a\u017e 100 metr\u016f, kter\u00e9 se z v\u00fd\u0161ky p\u0159ibli\u017en\u011b 80 kilometr\u016f pohybuj\u00ed rychlost\u00ed t\u00e9m\u011b\u0159 10 procent rychlosti sv\u011btla dol\u016f k horn\u00ed vrstv\u011b oblak\u016f, p\u0159ibli\u017en\u011b nad m\u00edstem, kde p\u0159ed krati\u010dk\u00fdm okam\u017eikem ude\u0159il blesk od mraku k zemi.<\/p>\n

I kdy\u017e by se mohlo zd\u00e1t, \u017ee se rud\u00ed sk\u0159\u00edtci stali dob\u0159e prozkouman\u00fdmi jevy, opak je pravdou. D\u016fvodem je nejen pom\u011brn\u011b kr\u00e1tk\u00e1 doba jejich studia, ale i jejich komplikovan\u00e9 pozorov\u00e1n\u00ed. To klade opravdu velk\u00e9 po\u017eadavky zejm\u00e9na na zku\u0161enost fotografa. Sk\u0159\u00edtci mnohdy toti\u017e nejsou ani vid\u011bt a tak se opravdu \u010dasto spol\u00e9h\u00e1 na svou intuici a techniku. \u00dasp\u011b\u0161n\u00fdm nasn\u00edm\u00e1n\u00edm ale v\u0161e nekon\u010d\u00ed. Vzhledem k tomu, \u017ee se sn\u00edmaj\u00ed slab\u00e9 jevy ve vzd\u00e1lenostech n\u011bkolika set kilometr\u016f, pracuje se p\u0159i zpracov\u00e1n\u00ed \u201esk\u0159\u00edtk\u016f\u201c na hranici \u201educh\u016f\u201c. Duchy zde m\u00edn\u00edme slab\u00e9 obrazy jevu na po\u0159\u00edzen\u00e9m sn\u00edmku. A zde pr\u00e1v\u011b nastupuje role zpracovatele dat, tedy druh\u00e9ho autora Miloslava Druckm\u00fcllera, kter\u00fd data zpracoval do tohoto \u00fa\u017easn\u00e9ho portr\u00e9tu \u201erud\u00fdch sk\u0159\u00edtk\u016f\u201c.<\/p>\n

Na z\u00e1v\u011br n\u00e1m ji\u017e p\u0159\u00edslu\u0161\u00ed pouze autor\u016fm pod\u011bkovat za \u00fa\u017easn\u00fd portr\u00e9t neviditelna, kter\u00fd zaslali do sout\u011b\u017ee \u010cesk\u00e1 astrofotografie m\u011bs\u00edce, kterou za\u0161ti\u0165uje \u010cesk\u00e1 astronomick\u00e1 spole\u010dnost.
