Astronomicheskaya nedelya s 27 sentyabrya po 3 oktyabrya 2021 goda24.09.2021 7:01 | Aleksandr Kozlovskii
Na dannoi nedele 27 sentyabrya Merkurii proidet tochku stoyaniya s perehodom k popyatnomu dvizheniyu, a 29 sentyabrya Luna (F= 0,48-) proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora. 30 sentyabrya dolgoperiodicheskaya peremennaya zvezda V Kassiopei dostignet maksimuma bleska (6m). 1 oktyabrya Luna (F= 0,26-) proidet severnee zvezdnogo skopleniya Yasli (M44), a Merkurii - v polutora gradusah yuzhnee Spiki. V etot zhe den' dolgoperiodicheskaya peremennaya zvezda R Strel'ca dostignet maksimuma bleska (6m). 2 oktyabrya asteroid Garmoniya (40) vstupit v protivostoyanie s Solncem. 3 oktyabrya Luna (F= 0,13-) proidet severnee Regula, a takzhe proizoidet pokrytie Lunoi (F= 0,13-) zvezdy eta L'va (3,5m) pri vidimosti na Evropeiskoi chasti strany. Krome etogo, prodolzhaetsya period, kogda yarkie sputniki Yupitera tesno sblizhayutsya i pokryvayutsya drug drugom.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 30 gradusov, a dolgota dnya na toi zhe shirote - do 11 chasov 20 minut. Vidimyi diametr Solnca uvelichivaetsya do 31,97 minut dugi, a dvizhetsya ono po sozvezdiyu Devy. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 29 sentyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Tel'ca, Bliznecov, Raka i L'va, izmenyaya fazu ot 0,7- do 0,07- i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii (do 29 sentyabrya, a zatem - umen'shaya). Nachalo nedeli nochnoe svetilo provedet v sozvezdii Tel'ca. 28 sentyabrya nochnoe svetilo (F= 0,55-) pereidet v sozvezdie Bliznecov, gde primet fazu poslednei chetverti 29 sentyabrya. 30 sentyabrya lunnyi serp pereidet v sozvezdie Raka pri faze 0,33- i zakonchit zdes' svoi put' po nebu sentyabrya pri faze 0,31-. 1 oktyabrya Luna (F= 0,26-) proidet severnee rasseyannogo zvezdnogo skopleniya Yasli (M44), a na sleduyushii den' lunnyi serp pri faze 0,2- pereidet v sozvezdie L'va. Zdes' Luna 2 oktyabrya pri faze 0,13- proidet severnee Regula, a v sozvezdie Devy tonkii lunnyi serp voidet pri faze 0,03- 4 oktyabrya. Fazy Luny na dannoe vremya i na budushee.
