Astronomicheskaya nedelya s 14 po 20 dekabrya 2020 goda11.12.2020 5:55 | Aleksandr Kozlovskii
Na dannoi nedele 14 dekabrya nastupit maksimum deistviya meteornogo potoka Geminidy (ZHR= 120) iz sozvezdiya Bliznecov, a Luna (F= 0,0) pokroet Merkurii (ne vidno). V etot zhe den' Luna (F= 0,0) okazhetsya v nishodyashem uzle svoei orbity i proizoidet polnoe solnechnoe zatmenie, vidimoe v Yuzhnoi Amerike (v Rossii ne vidno). 15 dekabrya Luna (F= 0,02+) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora, a 17 dekabrya nochnoe svetilo (F= 0,08+) budet nahodit'sya bliz Yupitera i Saturna. 19 dekabrya dolgoperiodicheskaya peremennaya zvezda T Bol'shoi Medvedicy dostignet maksimuma bleska (6,5m), a 20 dekabrya Merkurii proidet verhnee soedinenie s Solncem. V etot zhe den' Luna (F= 0,39+) proidet yuzhnee Neptuna.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy sostavlyaet okolo 11 gradusov, a dolgota dnya na toi zhe shirote umen'shaetsya do 7 chasov 00 minut. Vidimyi diametr Solnca uvelichivaetsya do 32,52 minut dugi, a dvizhetsya ono po sozvezdiyu Zmeenosca do 18 dekabrya, perehodya zatem v sozvezdie Strel'ca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 14 dekabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Zmeenosca, Strel'ca, Kozeroga i Vodoleya, izmenyaya fazu ot 0 do 0,4+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Zmeenosca. Zdes' Luna primet fazu novoluniya 14 dekabrya. V eto novolunie proizoidet polnoe solnechnoe zatmenie, vidimoe v Yuzhnoi Amerike. 14 dekabrya Luna pereidet v sozvezdie Strel'ca i na vechernee nebo. 17 dekabrya Luna proidet yuzhnee Yupitera i Saturna pri faze 0,08+, nablyudayas' nizko nad gorizontom na vechernem nebe. V etot zhe den' lunnyi serp pereidet v sozvezdie Kozeroga i probudet zdes' do 19 dekabrya, uvelichiv fazu do 0,24+. V sozvezdii Vodoleya Luna 20 dekabrya proidet yuzhnee Neptuna pri faze 0,39+. Fazy Luny na dannoe vremya i na budushee.

Efemeridy Solnca, Luny i planet na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ .
Iz komet hvostataya strannica ATLAS (C/2020 M3) dvizhetsya po sozvezdiyu Voznichego s bleskom okolo 9m. Karty putei komet i asteroidov na mesyac imeyutsya v KN na dekabr', a na drugie periody - v Astronomicheskom kalendare na 2020 god i Astronomicheskom kalendare na 2021 god.

Sredi asteroidov naibolee yarkimi na dannoi nedele budut: Vesta (7,5m) v sozvezdii L'va i Flora (9,0m) 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: R Del'fina 8,3m - 14 dekabrya, U Devy 8,2m - 18 dekabrya, R Strel'ca 7,3m - 18 dekabrya, T Bol'shoi Medvedicy 7,7m - 19 dekabrya.
