Astronomicheskaya nedelya s 22 po 28 noyabrya 2021 goda19.11.2021 7:10 | Aleksandr Kozlovskii
Na dannoi nedele 22 noyabrya nastupit maksimum deistviya meteornogo potoka al'fa-Monocerotidy iz sozvezdiya Edinoroga (ZHR= 5), a dolgoperiodicheskaya peremennaya zvezda R Lisichki dostignet maksimuma bleska (6m). V etot zhe den' Luna (F= 0,89-) proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora, a 23 noyabrya dolgoperiodicheskaya peremennaya zvezda S Malogo Psa dostignet maksimuma bleska (6,5m). 25 noyabrya Luna (F= 0,72-) proidet severnee zvezdnogo skopleniya Yasli (M44). 26 noyabrya proizoidet pokrytie Lunoi (F= 0,56-) zvezdy eta L'va (3,5m) pri vidimosti na bol'shei chasti strany, a Luna (F= 0,55-) proidet severnee Regula. 27 noyabrya dolgoperiodicheskaya peremennaya zvezda R Lebedya dostignet maksimuma bleska (7m). 28 noyabrya proizoidet pokrytie Lunoi (F= 0,35-) zvezdy nyu Devy (4m) pri vidimosti na Urale i v Sibiri. V etot zhe den' Cerera vstupit v protivostoyanie s Solncem, a Vesta - v soedinenie s Solncem.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 13 gradusov, a dolgota dnya na toi zhe shirote - do 7 chasov 35 minut. Vidimyi diametr Solnca uvelichivaetsya do 32,42 minut dugi, a dvizhetsya ono po sozvezdiyu Vesov, 23 noyabrya perehodya v sozvezdie Skorpiona. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 27 noyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Tel'ca, Bliznecov, Raka, L'va, Devy, izmenyaya fazu ot 0,95- do 0,35- i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Tel'ca. 22 noyabrya nochnoe svetilo (F= 0,93-) pereidet v sozvezdie Bliznecov, a 24 noyabrya - v sozvezdie Raka uzhe pri faze 0,79-. V sozvezdii Raka lunnyi oval (F= 0,72-) proidet 25 noyabrya severnee rasseyannogo zvezdnogo skopleniya Yasli (M44). V etot zhe den' Luna (F= 0,65-) pereidet v sozvezdie L'va, gde pri faze 0,55- proidet severnee Regula 26 noyabrya. Zdes' nochnoe svetilo 27 noyabrya primet fazu poslednei chetverti i ustremitsya k sozvezdiyu Devy, v kotoroe voidet pri faze 0,37- 28 noyabrya. Fazy Luny na dannoe vremya i na budushee.

Sredi asteroidov naibolee yarkoi na dannoi nedele budet Cerera (7,0m) v sozvezdii Tel'ca (bliz Al'debarana).
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: RV Strel'ca 8,5m - 22 noyabrya, R Lisichki 7,0m - 22 noyabrya, S Malogo Psa 7,7m - 23 noyabrya, S Malogo L'va 8,7m - 25 noyabrya, R Lebedya 8,1m - 27 noyabrya.
