Na dannoi nedele 23 noyabrya Luna (F= 0,63+) proidet yuzhnee Neptuna, a 24 noyabrya dolgoperiodicheskaya peremennaya zvezda R Zaica dostignet maksimuma bleska (6m). 25 noyabrya dolgoperiodicheskie peremennye zvezdy X Zmeenosca (6m) i T Kassiopei (6,5m) dostignut maksimuma bleska, a Luna (F= 0,82+) proidet yuzhnee Marsa. 26 noyabrya proizoidet pokrytie Lunoi (F= 0,88+) zvezdy nyu Ryb (4,5m) pri vidimosti na bol'shei chasti Rossii, a 27 noyabrya Luna (F= 0,90+) okazhetsya v apogee svoei orbity na rasstoyanii 405892 km ot centra Zemli. V etot zhe den' Luna (F= 0,93+) proidet yuzhnee Urana, a 29 noyabrya Neptun dostignet stoyaniya s perehodom k pryamomu dvizheniyu.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 12 gradusov, a dolgota dnya na toi zhe shirote - do 7 chasov 30 minut. Vidimyi diametr Solnca uvelichivaetsya do 32,44 minut dugi, a dvizhetsya ono po sozvezdiyu Skorpiona, 29 noyabrya perehodya v sozvezdie Zmeenosca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 30 noyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Vodoleya, Ryb, Ovna i Tel'ca, izmenyaya fazu ot 0,55+ do 1 i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Vodoleya. 23 noyabrya proidet yuzhnee Neptuna pri faze 0,63+, a na sleduyushii den' pereidet v sozvezdie Ryb, uvelichiv fazu do 0,7+. 25 noyabrya Luna budet nahodit'sya v sozvezdii Kita, a 26 noyabrya snova pereidet v sozvezdie Ryb (F= 0,85+), nahodyas' bliz Marsa. 27 noyabrya pochti polnaya Luna eshe raz posetit sozvezdie Kita pri faze bolee 0,9+, i v etot zhe den' pereidet v sozvezdie Ovna (bliz Urana). Zdes' Luna probudet do 29 noyabrya, kogda pereidet v sozvezdie Tel'ca. Fazy Luny na dannoe vremya i na budushee.

Sredi asteroidov naibolee yarkimi na dannoi nedele budut: Vesta (7,9m) v sozvezdii L'va i Flora (8,4m) v sozvezdii Kita.
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: T Zhirafa 8,0m - 24 noyabrya, R Zaica 6,8m - 24 noyabrya, Y Perseya 8,4m - 25 noyabrya, X Zmeenosca 6,8 - 25 noyabrya, RZ Pegasa 8,8m - 26 noyabrya, T Kassiopei 7,9m - 27 noyabrya.
