Astronomicheskaya nedelya s 19 po 25 dekabrya 2022 goda16.12.2022 8:31 | Aleksandr Kozlovskii
Na dannoi nedele 20 dekabrya Luna (F= 0,15-) okazhetsya v nishodyashem uzle svoei orbity, a 21 dekabrya Merkurii dostignet maksimal'noi vostochnoi (vechernei) elongacii 20 gradusov. V etot zhe den' nastupit zimnee solncestoyanie, a Luna (F= 0,03-) proidet severnee Antaresa. 22 dekabrya nastupit maksimum deistviya meteornogo potoka Ursidy (ZHR= 10) iz sozvezdiya Maloi Medvedicy, a 23 dekabrya Luna (F= 0,01+) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora. 24 dekabrya Luna (F= 0,02+) dostignet perigeya svoei orbity na rasstoyanii 358270 km ot centra Zemli (bliz Merkuriya i Venery). Krome etogo, dlya lyubitel'skih teleskopov dostupny dve komety (ZTF (C/2020 V2) i ZTF (C/2022 E3)), kotorye postepenno uvelichivayut blesk.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy priderzhivaetsya znacheniya 11 gradusov, a dolgota dnya na toi zhe shirote - do 07 chasov 00 minut. Vidimyi diametr Solnca uvelichivaetsya ot 32,50 do 32,52 minut dugi, a dvizhetsya ono po sozvezdiyu Strel'ca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 23 dekabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Devy, Vesov, Skorpiona, Zmeenosca, Strel'ca i Kozeroga, izmenyaya fazu ot 0,24- do 0,1+ i umen'shaya (s 23 dekabrya - uvelichivaya) sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Devy. 19 dekabrya lunnyi serp pri faze 0,18- pereidet v sozvezdie Vesov. 21 dekabrya tonkii mesyac (F= 0,07-) pereidet v sozvezdie Skorpiona, a pri faze 0,04- - v sozvezdie Zmeenosca, nablyudayas' severnee Antaresa. V etom sozvezdii lunnyi serp budet nahodit'sya do 23 dekabrya, kogda pri faze 0,01- pereidet v sozvezdie Strel'ca. V etom sozvezdii Luna primet fazu novoluniya i probudet zdes' do 25 dekabrya. 24 dekabrya molodoi mesyac pri faze 0,02+ proidet yuzhnee Venery i Merkuriya, a zatem (uzhe 25 dekabrya) pereidet v sozvezdie Kozeroga, uvelichiv fazu do 0,05+. Fazy Luny na dannoe vremya i na budushee.
