Na dannoi nedele 20 noyabrya Luna (F= 0,52+) proidet yuzhnee Saturna, a 21 noyabrya pri faze 0,66+ dostignet perigeya svoei orbity na rasstoyanii 369824 km ot centra Zemli. 22 noyabrya nastupit maksimum deistviya meteornogo potoka al'fa-Monocerotidy (ZHR= 5 i bolee) iz sozvezdiya Edinoroga, a Luna (F= 0,71+) proidet yuzhnee Neptuna (pokrytie pri vidimosti v Antarktide). 24 noyabrya Luna (F= 0,90+) okazhetsya v voshodyashem uzle svoei orbity, a 25 noyabrya pri faze 0,95+ proidet severnee Yupitera. 26 noyabrya Luna (F= 0,99+) prohodit severnee Urana. Krome etogo, na utrennem nebe nablyudaetsya kometa P/Hartley (103P) s bleskom okolo 9m v sozvezdii Gidry.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shitsya do 13 gradusov, a dolgota dnya na toi zhe shirote - do 7 chasov 35 minut. Vidimyi diametr Solnca uvelichivaetsya ot 32,36 do 32,41 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 pervoi chetverti 20 noyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Kozeroga, Vodoleya, Ryb, Ovna i Tel'ca, izmenyaya fazu ot 0,44+ do 1,0 i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Kozeroga. Luna probudet zdes' do 20 noyabrya, uvelichiv fazu do 0,49+. Pereidya v sozvezdie Vodoleya lunnyi poludisk v etot den' primet fazu pervoi chetverti, a zatem (F= 0,52+) proidet yuzhnee Saturna. 22 noyabrya v sozvezdii Vodoleya pri faze 0,71+ Luna proidet yuzhnee Neptuna (pokrytie pri vidimosti v Antarktide). V etot zhe den' lunnyi oval (F= 0,74+) pereidet v sozvezdie Ryb, a 23 noyabrya pri faze okolo 0,8+ pobyvaet v sozvezdii Kita, vnov' pereidya v sozvezdie Ryb pri faze 0,83+. 24 noyabrya nochnoe svetilo (F= 0,92+) vstupit v sozvezdie Ovna, gde 25 noyabrya pri faze 0,95+ proidet severnee Yupitera, a 26 noyabrya pri faze 0,99+ - severnee Urana. V etot zhe den' Luna (F= 0,99+) pereidet v sozvezdie Tel'ca, gde 27 noyabrya primet fazu polnoluniya nablyudayas' vsyu noch' bliz Pleyad i Giad. Fazy Luny na dannoe vremya i na budushee.
