Astronomicheskaya nedelya s 20 po 26 noyabrya 2017 goda22.10.2017 20:02 | Aleksandr Kozlovskii
Na dannoi nedele Luna (F= 0,05+) proidet bliz Saturna. 21 noyabrya nastupit maksimum deistviya meteornogo potoka al'fa-Monocerotidy (ZHR= 5) iz sozvezdiya Edinoroga, Luna (F= 0,1+) proidet apogei svoei orbity na rasstoyanii ot centra Zemli 406130 km, a dolgoperiodicheskaya peremennaya zvezda R Orla dostignet maksimuma bleska (5m). 22 noyabrya Luna (F= 0,11+) dostignet maksimal'nogo sklonenii k yugu, a Neptun stoyaniya s perehodom k pryamomu dvizheniyu. V seredine nedeli Merkurii proidet tochku maksimal'noi vostochnoi (vechernei) elongacii 22 gradusa. 25 noyabrya Luna (F= 0,3+) okazhetsya v nishodyashem uzle svoei orbity, a dolgoperiodicheskaya peremennaya zvezda RT Strel'ca dostignet maksimuma bleska (6m).
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya k koncu nedeli do 13 gradusov, a dolgota dnya na toi zhe shirote - do 7 chasov 40 minut. Vidimyi diametr Solnca za opisyvaemyi period uvelichitsya do 32,41 minut dugi, a dvizhetsya ono po sozvezdiyu Vesov, 23 noyabrya perehodya v sozvezdie Skorpiona. Tekushie dannye o Solnce i vid ego poverhnosti na dannoe vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 26 noyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Zmeenosca Strel'ca, Kozeroga i Vodoleya, izmenyaya fazu ot 0 do 0,5+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Zmeenosca. V noch' s 20 na 21 noyabrya molodoi mesyac vstupit v sozvezdie Strel'ca, dostignuv soedineniya s Saturnom pri faze 0,06+. Luna proidet severnee okol'covannoi planety i prodolzhit puteshestvie po sozvezdiyu Strel'ca. Zdes' rastushii serp budet nahodit'sya do 23 noyabrya, nablyudayas' nizko nad gorizontom, nahodyas' bliz apogeya orbity i maksimal'nogo yuzhnogo skloneniya. V sozvezdie Kozeroga Luna pereidet pri faze 0,24+ i budet uvelichivat' zdes' fazu pochti do poludiska. No fazu pervoi chetverti primet 26 noyabrya uzhe v sozvezdii Vodoleya. Faza Luny na tekushii moment. Fazy Luny na budushee.
