Astronomicheskaya nedelya s 11 po 17 dekabrya 2017 goda25.10.2017 18:01 | Aleksandr Kozlovskii
Na dannoi nedele 13 dekabrya Merkurii vstupit v nizhnee soedinenie s Solncem, a Luna (F=0,18-) proidet bliz Marsa, 14 dekabrya maksimuma deistviya dostignet meteornyi potok Geminidy (ZHR= 120) iz sozvezdiya Bliznecov, a Luna (F=0,11-) proidet bliz Yupitera. 15 dekabrya Merkurii proidet v 2,2 gradusa severnee Venery, a takzhe proizoidet pokrytie zvezdy HIP35256 (8,8m).iz sozvezdiya Bliznecov asteroidom 1046 pri vidimosti na Kamchatke i v Primor'e.16 dekabrya dolgoperiodicheskaya peremennaya zvezda U Kita bliz maksimuma bleska (6,5m), a v konce nedeli Luna (F= 0,05-) sblizitsya s Merkuriem i Veneroi. Krome etogo, Vesta vsyu nedelyu nahoditsya bliz Yupitera.
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 32,50 minut dugi, a dvizhetsya ono po sozvezdiyu Zmeenosca. 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 Devy, Vesov, Skorpiona i Zmeenosca, izmenyaya fazu ot 0,5- do 0 i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Devy. Sovershaya put' po dekabr'skomu nebu, tayushii serp 13 dekabrya pri faze okolo 0,2- proidet severnee Spiki, a zatem i Marsa. Pereidya v sozvezdie Vesov 14 dekabrya, Luna proidet v etot zhe den' severnee Yupitera (bliz al'fa Vesov) pri faze okolo 0,1-. 16 dekabrya tonkii serp dostignet sozvezdiya Skorpiona, i v etot zhe den' vstupit vo vladeniya sozvezdiya Zmeenosca, zakanchivaya utrennyuyu vidimost'. 17 dekabrya stareyushii mesyac proidet bliz Merkuriya i Venery. Faza Luny na tekushii moment. Fazy Luny na budushee.
Iz planet Solnechnoi sistemy: Venera i Saturn ne vidny, a Merkurii nachinaet utrennyuyu vidimost' na fone zari. Mars i Yupiter nablyudayutsya v utrennie chasy, a Uran i Neptun vidny v vechernee i nochnoe vremya.

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: 11 dekabrya - v 1852 godu, 12 dekabrya - v 1890 godu, 13 dekabrya - v 1536 godu, 14 dekabrya - v 1648 godu, 15 dekabrya - v 1563 godu, 16 dekabrya - v 1694 godu, 17 dekabrya - v 1713 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 13 i 16 dekabrya (po 6 zatmenii!), a men'she vsego - 11 dekabrya (1 zatmenie).
