Hlavn\u00edm c\u00edlem leto\u0161n\u00ed expedice byla kalibrace meteorick\u00e9ho radaru \u201eK\u00e1konovc\u016f\u201c. Ten funguje tak, \u017ee p\u0159ij\u00edm\u00e1 vzd\u00e1len\u00fd radarov\u00fd vys\u00edla\u010d, kter\u00fd ov\u0161em z\u00a0na\u0161\u00ed polohy nen\u00ed sly\u0161iteln\u00fd. Pr\u016flet meteoru ionizuje vzduch a ten pak funguje jako jak\u00e9si \u201ezrcadlo\u201c. Aparatura k\u00a0tomuto je velmi trivi\u00e1ln\u00ed, sta\u010d\u00ed jen zdroj elekt\u0159iny, po\u010d\u00edta\u010d, p\u0159ij\u00edma\u010d a jednoduch\u00e1 ant\u00e9na. Radar meteory \u00fasp\u011b\u0161n\u011b detekuje, av\u0161ak v\u00a0sou\u010dasnosti neum\u00ed ur\u010dit jejich dr\u00e1hu. \u00dakolem tedy bylo, pokusit se o ztoto\u017en\u011bn\u00ed opticky pozorovan\u00fdch meteor\u016f s\u00a0radiov\u00fdmi. A nebylo lep\u0161\u00edho m\u00edsta, ne\u017e h\u0159eben Grun\u011b, kam se sjeli pozorovatel\u00e9 Spole\u010dnosti pro meziplanet\u00e1rn\u00ed hmotu. Z\u00e1rove\u0148 je opod\u00e1l um\u00edst\u011bna kamera s\u00edt\u011b CEMeNT na B\u00edl\u00e9m k\u0159\u00ed\u017ei.<\/p>\n

Po\u010das\u00ed n\u00e1m letos p\u0159\u00e1lo jen \u010d\u00e1ste\u010dn\u011b \u2013 prvotn\u00ed pesimistick\u00e9 odhady se nevyplnily a tak n\u00e1m v\u00a0noci kolem maxima tu a tam p\u0159ech\u00e1zela n\u011bjak\u00e1 vysok\u00e1 obla\u010dnost, av\u0161ak v\u011bt\u0161inu \u010dasu bylo alespo\u0148 70% ji\u017en\u00ed \u010d\u00e1sti oblohy jasn\u00e9. V \u201e\u00fa\u017easn\u00fdch\u201c -10 \u00b0C jsme vyrazili na stanovi\u0161t\u011b, kde jsme si vyhrabali ve sn\u011bhu m\u00edsta k\u00a0pozorov\u00e1n\u00ed. Na aut\u011b, kter\u00e9 tak\u00e9 slou\u017eilo jako zdroj elekt\u0159iny, jsme postavili ant\u00e9nu radaru a pozorov\u00e1n\u00ed mohlo za\u010d\u00edt. Hlavn\u00ed organiz\u00e1tor tohoto pozorov\u00e1n\u00ed Jakub K\u00e1kona k\u00a0tomu \u0159\u00edk\u00e1: \u201eBohu\u017eel se nepoda\u0159ilo naladit p\u0159ij\u00edma\u010d radaru v\u010das p\u0159ed maximem Geminid. D\u016fvodem byla z\u0159ejm\u011b velk\u00e1 zm\u011bna teploty. V\u00a0dob\u011b p\u0159ed maximem venkovn\u00ed teplota klesla hluboko pod bod mrazu. Dal\u0161\u00ed noc se sice p\u0159ij\u00edma\u010d naladit poda\u0159ilo, ale to se ji\u017e obloha zat\u00e1hla a nebylo mo\u017en\u00e9 pokra\u010dovat v\u00a0optick\u00e9m pozorov\u00e1n\u00ed. Mohli jsme tedy pouze porovnat po\u010dty registrovan\u00fdch meteor\u016f oproti radiov\u00fdm stanic\u00edm um\u00edst\u011bn\u00fdm v\u00edce na z\u00e1pad. Na dan\u00e9 k\u00f3t\u011b bylo pozorov\u00e1no \u00be meteor\u016f nap\u0159\u00edklad oproti stanici v\u00a0\u010cesk\u00fdch Bud\u011bjovic\u00edch. V absolutn\u00edch hodnot\u00e1ch to znamen\u00e1 17 a\u017e 63 meteor\u016f za hodinu (15. 12., tedy mimo maximum Geminid). B\u011bhem pozorov\u00e1n\u00ed 15. 12. byly mimo jin\u00e9 zachyceny dva \u201eradiov\u00e9 bolidy\u201c. Jeden z\u00a0nich byl pozorov\u00e1n tak\u00e9 stanic\u00ed s\u00edt\u011b SMRST ve Vset\u00edn\u011b na jin\u00e9 vlnov\u00e9 d\u00e9lce.\u201c<\/p>\n

Onu dal\u0161\u00ed noc po maximu, tedy 15.12 jsme u\u010dinili pokus o v\u00fdjezd za jasnou oblohou. H\u0159ebeny Beskyd toti\u017e halila hust\u00e1 \u010depice, ale mimo hory je\u0161t\u011b zb\u00fdvalo asi dvouhodinov\u00e9 okno p\u0159ed p\u0159\u00edchodem obla\u010dnosti ze z\u00e1padu. Vyrazili jsme tedy sm\u011brem na \u010celadnou. Na m\u00edst\u011b v\u0161ak Jakub Koukal cht\u011bl je\u0161t\u011b kousek na jih a tak jsme zam\u00ed\u0159ili ke golfov\u00fdm h\u0159i\u0161t\u00edm, kde m\u011bla b\u00fdt d\u00edra mezi orografick\u00fdmi mraky. Bohu\u017eel na m\u00edst\u011b sam\u00e9m foukal v\u00edtr s\u00edly ork\u00e1nu, kter\u00fd znemo\u017e\u0148oval ustaven\u00ed kamery. Prorazili jsme tedy tvo\u0159\u00edc\u00ed se z\u00e1v\u011bje a zvolili pl\u00e1n B, zam\u00ed\u0159it ke zn\u00e1m\u00fdm na chalupu cca 2 km daleko. Tam jsme je v\u00a0noci \u201ep\u0159epadli\u201c, po\u017e\u00e1dali o elekt\u0159inu a v\u00a0z\u00e1v\u011bt\u0159\u00ed postavili kameru. Ta fungovala asi 5 minut a pot\u00e9 u\u017e p\u0159i\u0161ly mraky. Na\u0161t\u011bst\u00ed ne v\u0161echny kamery s\u00edt\u011b CEMeNT m\u011bly stejnou sm\u016flu a tak se Jakubovi Koukalovi poda\u0159ilo zjistit 1330 v\u00edcestani\u010dn\u00edch drah Geminid.<\/p>\n

Dal\u0161\u00ed den, tedy v\u00a0sobotu se konal semin\u00e1\u0159. P\u0159edn\u00e1\u0161ky se t\u00fdkaly zejm\u00e9na komet a pozorov\u00e1n\u00ed meteor\u016f. Mimo ofici\u00e1ln\u00ed t\u00e9ma promluvil Jan Kondziolka o Beskydsk\u00e9 oblasti tmav\u00e9 oblohy (proto\u017ee se semin\u00e1\u0159 kon\u00e1 pr\u00e1v\u011b v\u00a0n\u00ed) a Milada Moudr\u00e1 o m\u011b\u0159en\u00ed jasu oblohy pomoc\u00ed digit\u00e1ln\u00ed zrcadlovky. Nejv\u011bt\u0161\u00ed diskuzi v\u0161ak rozpoutal p\u0159\u00edsp\u011bvek Martina K\u00e1kony o jejich radarov\u00e9m pozorov\u00e1n\u00ed meteor\u016f, vznikly nov\u00e9 my\u0161lenky a podn\u011bty ke spolupr\u00e1ci.<\/p>\n
