Astronomicheskaya nedelya s 18 po 24 dekabrya 2017 goda25.10.2017 22:10 | Aleksandr Kozlovskii
Na dannoi nedele Luna (F= 0,0) proidet bliz Saturna, a asteroid (20) Massaliya (8,4m) okazhetsya v protivostoyanii s Solncem (18 dekabrya). 19 dekabrya Luna dostignet apogeya orbity (406605 km) i maksimal'nogo skloneniya k yugu. Na sleduyushii den' dolgoperiodicheskie peremennye zvezdy R Drakona i T Vodoleya budut nahodit'sya bliz maksimuma bleska (6,5m), a 21 dekabrya nastupit zimnee solncestoyanie i Saturn proidet soedinenie s Solncem. Na sleduyushii den' budet imet' mesto maksimum deistviya meteornogo potoka Ursidy (ZHR= 10) iz sozvezdiya Maloi Medvedicy, a Luna okazhetsya v nishodyashem uzle orbity. 23 dekabrya Merkurii dostignet stoyaniya s perehodom k pryamomu dvizheniyu, a v konce nedeli Luna (F= 0,32+) proidet bliz Neptuna.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy priderzhivaetsya znacheniya 11 gradusov, a dolgota dnya na toi zhe shirote - 7 chasov 00 minut. Vidimyi diametr Solnca za opisyvaemyi period uvelichitsya do 32,52 minut dugi, a dvizhetsya ono po sozvezdiyu Strel'ca. Vid poverhnosti Solnca na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 18 dekabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Zmeenosca, Strel'ca, Kozeroga i Vodoleya, izmenyaya fazu ot 0 do 0,35+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Zmeenosca. 18 dekabrya Luna primet fazu novoluniya u granicy sozvezdii Zmeenosca i Strel'ca, i pereidet na vechernee nebo. V sozvezdii Strel'ca molodoi mesyac vstupit v soedinenie s Saturnom pri minimal'noi rastushei faze. Luna proidet severnee okol'covannoi planety i prodolzhit puteshestvie po sozvezdiyu Strel'ca, chtoby 18 dekabrya okazat'sya bliz apogeya orbity i maksimal'nogo yuzhnogo skloneniya. V etom sozvezdii rastushii serp budet nahodit'sya do 21 dekabrya, nablyudayas' vecherom nizko nad gorizontom. V sozvezdie Kozeroga Luna pereidet pri faze menee 0,1+, i budet uvelichivat' ee do 0,2+, proidya nishodyashii uzel orbity 22 dekabrya. V sozvezdie Vodoleya lunnyi serp pereidet 23 dekabrya, a na sleduyushii den' sblizitsya s Neptunom pri faze bolee 0,3+. Pokrytiya planety na etot raz ne proizoidet, t.k. seriya pokrytii Neptuna zakonchilas', a sleduyushaya seriya nachnetsya v 2023 godu. Faza Luny na tekushii moment. Fazy Luny na budushee.

Nedel'nyi obzor ot zhurnala "Skai end Teleskop", no nuzhno uchityvat', chto kartinki dayutsya dlya 40 severnoi shiroty, a polozhenie Luny i planet na 7 chasov pozdnee otnositel'no moskovskogo vremeni!
Yasnogo neba i uspeshnyh nablyudenii!
Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 18 dekabrya - v 1191 godu, 19 dekabrya - v 1340 godu, 20 dekabrya - v 0819 godu, 21 dekabrya - v 1843 godu, 22 dekabrya - v 1889 godu, 23 dekabrya - v 1908 godu, 24 dekabrya - v 1554 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 22 dekabrya (7 zatmenii!), a men'she vsego - 20 i 21 dekabrya (po 2 zatmeniya).
