Prv\u00fd zimn\u00fd de\u0148 a s n\u00edm spojen\u00fd zimn\u00fd slnovrat sa za\u010dal 21. decembra presne o 11:02 stredoeur\u00f3pskeho \u010dasu. V tento v\u00fdznamn\u00fd de\u0148 sa okrem najdlh\u0161ej noci a najkrat\u0161ieho d\u0148a odohralo aj vesm\u00edrne divadlo v podan\u00ed Jupitera a Saturnu. Tieto dve plynn\u00e9 plan\u00e9ty sa bezprostredne po z\u00e1pade slnka prekryli a vytvorili tak konjunkciu, ktor\u00e1 nastane najbli\u017e\u0161ie a\u017e v roku 2080. Ten kto zme\u0161kal mus\u00ed d\u00fafa\u0165, \u017ee o 60 rokov bude jasn\u00e1 noc. Podmienky na pozorovanie tohto \u00fakazu boli bohu\u017eia\u013e vhodn\u00e9 len do 20. decembra, kedy na v\u00e4\u010d\u0161ine n\u00e1\u0161ho \u00fazemia trvalo inverzn\u00e9 po\u010dasie. S\u00edce bolo nutn\u00e9 vyst\u00fapa\u0165 nad hranicu 1300 m.n.m, no pozorovanie st\u00e1lo za to, ke\u010f\u017ee i\u0161lo o druh\u00fd najjasnej\u0161\u00ed objekt na no\u010dnej oblohe po Mesiaci. 21. decembra sa dlhodobo inverzn\u00e9 po\u010dasie za\u010dalo meni\u0165. Od juhoz\u00e1padu k n\u00e1m za\u010dal pr\u00fadi\u0165 front\u00e1lny syst\u00e9m, ktor\u00fd zdvihol obla\u010dnos\u0165 a postupne priniesol teplo a d\u00e1\u017e\u010f.<\/p>\n\n\n\n

Astronomick\u00e1 zima je s\u00edce tu, ale vonku to sk\u00f4r pripom\u00edna neskor\u00fa jese\u0148. Teploty sa od za\u010diatku t\u00fd\u017ed\u0148a pohybuj\u00fa v plusov\u00fdch hodnot\u00e1ch a pod bod mrazu sa dostali ledva iba na vrcholoch Vysok\u00fdch Tatier. Zr\u00e1\u017eky pri\u0161li najm\u00e4 vo forme da\u017e\u010fa. Sne\u017eilo op\u00e4\u0165 len v najvy\u0161\u0161\u00edch poloh\u00e1ch, ale o v\u00fdraznom pr\u00edrastku snehovej pokr\u00fdvky nem\u00f4\u017ee by\u0165 ani re\u010d. Chodn\u00edky v dolin\u00e1ch boli ukryt\u00e9 pod vodou a lezeck\u00e9 podmienky pripom\u00ednali sk\u00f4r chladn\u00e9 letn\u00e9 dni. Such\u00e1 skala a blatist\u00e9 tr\u00e1vy. V\u00fdh\u013ead na nadch\u00e1dzaj\u00faci v\u00edkend je v\u0161ak o nie\u010do optimistickej\u0161\u00ed. Teplota z noci \u0160tedr\u00e9ho d\u0148a do r\u00e1na Prv\u00e9ho sviatku viano\u010dn\u00e9ho prudko klesla na -10\u00b0C na Lomnickom \u0161t\u00edte. V kombin\u00e1cii s mokr\u00fdm podkladom by to pre lezcov mohlo predstavova\u0165 n\u00e1dejn\u00e9 svetielko v suchej tme. Aspo\u0148 sa v\u0161etci nebud\u00fa sprchova\u0165 v Grossovom \u013eadop\u00e1de a \u010dlenky v n\u00e1stupoch a zostupoch nebud\u00fa to\u013eko trpie\u0165.<\/p>\n\n\n\n

Lav\u00ednov\u00e1 situ\u00e1cia posledn\u00fdch dn\u00ed nepotrebuje koment\u00e1r. Sneh treba poctivo h\u013eada\u0165. A ten \u010do sa n\u00e1jde je zv\u00e4\u010d\u0161a tvrd\u00fd. No napriek tomu m\u00f4\u017ee by\u0165 nebezpe\u010dn\u00fd, o \u010dom sved\u010d\u00ed lav\u00ednov\u00e1 nehoda z minul\u00e9ho t\u00fd\u017ed\u0148a. V profiloch sa \u010dasto pod tvrdou vrchnou vrstvou objavuje hranatozrnn\u00fd sneh a ten nep\u00f4sob\u00ed v\u00f4bec s\u00fadr\u017ene. Pr\u00e1ve naopak. Pri rezan\u00ed profilu sa pri zemi vys\u00fdpa a tak vrchn\u00fa vrstvu zna\u010dne oslabuje. Nebezpe\u010dn\u00e9 s\u00fa najm\u00e4 strm\u00e9 a extr\u00e9mne strm\u00e9 svahy a n\u00e1stupov\u00e9 trasy pod skaln\u00e9 steny.

Tohtoro\u010dn\u00e1 zima nepraje ani skialpinistom a ly\u017eiarom. Kto sa chce prejs\u0165 a poly\u017eova\u0165 si, je odk\u00e1zan\u00fd na umel\u00fd sneh ly\u017eiarskych stred\u00edsk.

Konkr\u00e9tne od 13:00 do 16:00.
