V\u00fdsledn\u00fd sn\u00edmek, ukazuj\u00edc\u00ed na 60 meteor\u016f tohoto roje, zabral p\u0159es 386 hodin \u010dist\u00e9ho \u010dasu sn\u00edm\u00e1n\u00ed a dal\u0161\u00edch asi 100 hodin detektivn\u00ed pr\u00e1ce.<\/p>\n

Aktualizace: V p\u00e1tek 25. \u010dervence 2025 byl z\u00e1b\u011br publikov\u00e1n jako Astronomick\u00fd sn\u00edmek dne NASA<\/a>.<\/p>\n

„Na prvn\u00ed pohled se m\u016f\u017ee zd\u00e1t, \u017ee jde o hezk\u00fd obr\u00e1zek Perseid. Ale tenhle sn\u00edmek zobrazuje n\u011bco mnohem m\u00e9n\u011b zn\u00e1m\u00e9ho a velmi neb\u011b\u017en\u011b zachytiteln\u00e9ho. A je za t\u00edm fakt kus pr\u00e1ce a trp\u011blivosti. Jedn\u00e1 se toti\u017e o \u010dasosb\u011brn\u00fd sn\u00edmek meteorick\u00e9ho roje \u03ba-Cygnid, k n\u011bmu\u017e se data sb\u00edrala dlouh\u00fdch 12 let<\/em>,“ popisuje Hor\u00e1lek sv\u016fj fotografick\u00fd projekt, na kter\u00fd nebyl s\u00e1m. Zachycen\u00e9 meteory podle jeho slov n\u00e1sledn\u011b matematicky vregistroval do sc\u00e9ny na pl\u00e1\u017ei Elafonisi na jihoz\u00e1pad\u011b \u0159eck\u00e9ho ostrova Kr\u00e9ta, kde meteor\u016f z tohoto prakticky nezn\u00e1m\u00e9ho roje zachytil spolu s kolegy Josefem Kujalem a Tom\u00e1\u0161em Slovinsk\u00fdm d\u00edky jejich zv\u00fd\u0161en\u00e9 aktivit\u011b v roce 2021 nejv\u00edce. Proto jsou meteory vyobrazeny na pozad\u00ed srpnov\u00e9 no\u010dn\u00ed scen\u00e9rie z 11. srpna 2021 na kr\u00e9tsk\u00e9 pl\u00e1\u017ei Elafonisi v \u0158ecku.<\/p>\n

Meteory ale s kolegy „nesb\u00edral“ jen v \u0158ecku. Pozorov\u00e1n\u00ed prob\u00edhalo ve velk\u00e9 m\u00ed\u0159e u Hor\u00e1lkovy domovsk\u00e9 Se\u010dsk\u00e9 p\u0159ehrady na Chrudimsku, ale tak\u00e9 v Parku tmav\u00e9 oblohy Poloniny na v\u00fdchod\u011b Slovenska nebo na chorvatsk\u00e9m Hvaru. „D\u016fvod, pro\u010d jsem pozorov\u00e1n\u00ed situoval na r\u016fzn\u00e1 m\u00edsta, je prost\u00fd: Musel jsem v\u017edy jezdit do m\u00edst, kde p\u0159edpov\u011b\u010f slibovala jasn\u00e9 po\u010das\u00ed na n\u011bkolik noc\u00ed kolem maxima roje<\/em>,“ vysv\u011btluje Hor\u00e1lek. Dal\u0161\u00edm faktorem, kter\u00fd v\u00fdznamn\u011b ovliv\u0148oval pozorov\u00e1n\u00ed, byla f\u00e1ze M\u011bs\u00edce. V t\u011bch letech, kdy se M\u011bs\u00edc nach\u00e1zel okolo maxima roje ve f\u00e1zi bl\u00edzk\u00e9 \u00fapl\u0148ku, Hor\u00e1lek ani jeho kolegov\u00e9 nefotili, nebo\u0165 jasn\u00fd svit na\u0161eho kosmick\u00e9ho souseda oblohu p\u0159esv\u00edtil a meteory se nedaly sn\u00edmat. Konkr\u00e9tn\u011b \u0161lo o roky 2014, 2017, 2019 a 2022. „Dal\u0161\u00ed nep\u0159\u00edzniv\u00fd rok je pr\u00e1v\u011b ten leto\u0161n\u00ed, proto jsem se nam\u00edsto dal\u0161\u00edho focen\u00ed rozhodl letos sn\u00edmek kone\u010dn\u011b zpracovat<\/em>,“ m\u00edn\u00ed Hor\u00e1lek.<\/p>\n

„Meteoric\u00fd roj \u03ba-Cygnid vrchol\u00ed ka\u017edoro\u010dn\u011b t\u00e9m\u011b\u0159 ve stejnou dobu jako Perseidy. P\u0159esn\u011bji \u0159e\u010deno aktivn\u00ed je mezi 3. a 25. srpnem, s maximem okolo 17. srpna<\/em>,“ upozor\u0148uje pracovn\u00edk Fyzik\u00e1ln\u00edho \u00fastavu v Opav\u011b. N\u00e1zev p\u0159itom roj nese po hv\u011bzd\u011b Kappa (\u03ba) v souhv\u011bzd\u00ed Labut\u011b, odkud pomal\u00e9 meteory s rychlost\u00ed pouh\u00fdch 25 km\/s, tedy v\u00edce jak dvakr\u00e1t pomalej\u0161\u00ed ne\u017e Perseidy, zd\u00e1nliv\u011b vyl\u00e9taj\u00ed. Na rozd\u00edl od Perseid maj\u00ed velmi n\u00edzkou frekvenci meteor\u016f, v dob\u011b maxima jen asi 3 meteory za hodinu. „Pokud jste n\u011bkdy sledovali Perseidy n\u011bkolik noc\u00ed v kuse, je vysoce pravd\u011bpodobn\u00e9, \u017ee jste spat\u0159ili i n\u011bjakou tu \u03ba-Cygnidu, ani\u017e byste o tom v\u011bd\u011bli<\/em>,“ dod\u00e1v\u00e1 se\u010dsk\u00fd autor sn\u00edmku.<\/p>\n

Samoz\u0159ejm\u011b krom\u011b Perseid a \u03ba-Cygnid prob\u00edhaj\u00ed v noc\u00edch v polovin\u011b srpna je\u0161t\u011b dal\u0161\u00ed m\u00e9n\u011b aktivn\u00ed roje (nap\u0159\u00edklad Ji\u017en\u00ed Delta Aquaridy, antiheliov\u00fd zdroj, sporadick\u00e9 meteory), ale \u03ba-Cygnidy jsou tak tro\u0161ku specifick\u00e9. Pat\u0159\u00ed k t\u011bm roj\u016fm, kter\u00e9 maj\u00ed nezn\u00e1m\u00fd p\u016fvod, a\u010dkoliv se ve v\u011bdeck\u00fdch kruz\u00edch u\u017e del\u0161\u00ed dobu s v\u00e1\u017enost\u00ed diskutuje, \u017ee s nejv\u011bt\u0161\u00ed pravd\u011bpodobnost\u00ed jsou zp\u016fsobeny rozdrolen\u00fdm materi\u00e1lem planetky 2008 ED69.

A co je nejzaj\u00edmav\u011bj\u0161\u00ed, ka\u017ed\u00fdch 7 let se u roje d\u00e1 pozorovat vy\u0161\u0161\u00ed aktivita zp\u016fsoben\u00e1 vlivem gravitace ob\u0159\u00ed planety Jupiter na proud roje. „Naposledy se takov\u00e1 vy\u0161\u0161\u00ed aktivita odehr\u00e1la ve zm\u00edn\u011bn\u00e9m roce 2021, ze kter\u00e9ho tak\u00e9 poch\u00e1z\u00ed nejv\u00edce zaznamenan\u00fdch meteor\u016f na sn\u00edmku.

Sn\u00edmek ale nezobrazuje meteory pouze z roku 2021. „Proto\u017ee jsem \u03ba-Cygnidy sledoval od roku 2012, p\u0159esn\u011bji \u0159e\u010deno v\u00edce jak 386 hodin v pr\u016fb\u011bhu 51 noc\u00ed, poda\u0159ilo se mi jich zachytit na \u0161est des\u00edtek<\/em>,“ up\u0159es\u0148uje Hor\u00e1lek. „Mysl\u00edm, \u017ee meteorick\u00fd roj \u03ba-Cygnid t\u00edmto zp\u016fsobem nikdo p\u0159edt\u00edm nezachytil, proto\u017ee to vy\u017eadovalo dlouh\u00e9 roky sn\u00edm\u00e1n\u00ed. Tento selektivn\u00ed \u010dasosb\u011brn\u00fd sn\u00edmek, z n\u011bho\u017e jsou odfiltrov\u00e1ny ostatn\u00ed meteory, letadla a satelity, ukazuje, \u017ee 12 let sn\u00edm\u00e1n\u00ed je dostate\u010dn\u011b dlouh\u00e1 doba na to, aby \u03ba-Cygnidy vystoupily ze \u201est\u00ednu sl\u00e1vy\u201c mnohem aktivn\u011bj\u0161\u00edch Perseid<\/em>,“ uzav\u00edr\u00e1 pr\u00e1ci na sn\u00edmku Hor\u00e1lek.<\/p>\n

I letos budou \u03ba-Cygnidy vrcholit 17. srpna, tedy jen \u010dty\u0159i dny po maximu Perseid. Podm\u00ednky pro pozorov\u00e1n\u00ed obou roj\u016f v\u0161ak budou dosti nep\u0159\u00edzniv\u00e9, nebo\u0165 na obloze bude ru\u0161it sv\u00fdm svitem M\u011bs\u00edc jen n\u011bkolik dn\u00ed po \u00fapl\u0148ku. Mnohem lep\u0161\u00ed podm\u00ednky se nab\u00eddnou u\u017e v p\u0159\u00ed\u0161t\u00edm roce, kdy oba roje budou vrcholit v dob\u011b okolo m\u011bs\u00ed\u010dn\u00edho novu.<\/p>\n
