Astronomicheskaya nedelya s 24 po 30 dekabrya 2018 goda19.11.2018 13:16 | Aleksandr Kozlovskii
Na dannoi nedele 24 dekabrya Luna (F= 0,96-) proidet perigei svoei orbity na rasstoyanii 361060 km ot centra Zemli okolo voshodyashego uzla svoei orbity. 25 dekabrya nochnoe svetilo proidet bliz zvezdnogo skopleniya Yasli (M44), a 26 dekabrya Luna (F= 0,8-) sblizitsya s Regulom. 27 dekabrya dolgoperiodicheskaya peremennaya zvezda S Bol'shoi Medvedicy dostignet maksimuma bleska (7m), a 29 dekabrya asteroid (6) Geba (8,5m) vstupit v protivostoyanie s Solncem. Nevooruzhennym glazom vidna kometa P/Wirtanen (46P), kotoraya dvizhetsya po sozvezdiyam Voznichego i Rysi i yavlyaetsya nezahodyashim svetilom v srednih i severnyh shirotah. V nachale nedeli ona budet nahodit'sya okolo zvezdy Kapella.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy priderzhivaetsya 11 gradusov, a dolgota dnya na toi zhe shirote - okolo 7 chasov 00 minut. Vidimyi diametr Solnca za opisyvaemyi period uvelichivaetsya do 32,54 minut dugi, a dvizhetsya ono po sozvezdiyu Strel'ca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 29 dekabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Bliznecov, Raka, L'va, Devy, izmenyaya fazu ot 1,0 do 0,35- i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Bliznecov, nahodyas' bliz maksimal'nogo skloneniya k severu ot nebesnogo ekvatora i perigeya svoei orbity. 24 dekabrya Luna dostignet sozvezdiya Raka pri faze 0,95-, nahodyas' yuzhnee komety P/Stephan-Oterma (38P). Zdes' 25 dekabrya nochnoe svetilo pri faze 0,92- peresechet rasseyannoe zvezdnoe skoplenie Yasli (M44) bliz voshodyashego uzla svoei orbity. Pri faze 0,88- lunnyi oval 25 dekabrya dostignet sozvezdiya L'va i ustremitsya k Regulu, severnee kotorogo proidet na sleduyushii den' pri faze 0,8-. V sozvezdii L'va 28 dekabrya, kogda pri faze 0,62- pereidet v sozvezdie Devy. Zdes' Luna primet fazu poslednei chetverti 29 dekabrya, a 30 dekabrya proidet severnee Spiki pri faze 0,38-. Fazy Luny na dannoe vremya i na budushee.

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 24 dekabrya - v 1554 godu, 25 dekabrya - v 1666 godu, 26 dekabrya - v 1144 godu, 27 dekabrya - v 1693 godu, 28 dekabrya - v 1712 godu, 29 dekabrya - v 1731 godu, 30 dekabrya - v 0251 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 27 dekabrya (7 zatmenii), a men'she vsego 26, 29 i 30 dekabrya (po 1 zatmeniyu).
