Astronomicheskaya nedelya s 16 po 22 oktyabrya 2023 goda13.10.2023 10:48 | Aleksandr Kozlovskii
Na dannoi nedele 18 oktyabrya Luna (F= 0,15+) proidet severnee Antaresa (pokrytie pri vidimosti na Evropeiskoi chasti Rossii), a Merkurii proidet v 3 gr. severnee Spiki. 20 oktyabrya Merkurii vstupit v verhnee soedinenie s Solncem, a Luna (F= 0,32+) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora. 21 oktyabrya nastupit maksimum deistviya meteornogo potoka Orionidy (ZHR= 15). Krome etogo, na utrennem nebe nahodyatsya dve komety s bleskom okolo 7m (P/Encke (2P) v sozvezdii Devy i P/Hartley (103P) v sozvezdiyah Bliznecov i Raka).
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shitsya do 23 gradusov, a dolgota dnya na toi zhe shirote - do 9 chasov 55 minut. Vidimyi diametr Solnca uvelichivaetsya ot 32,08 do 32,14 minut dugi, a dvizhetsya ono po sozvezdiyu Devy. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 22 oktyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Devy, Vesov, Skorpiona, Zmeenosca, Strel'ca i Kozeroga, izmenyaya fazu ot 0,02+ do 0,59+ i umen'shaya (s 20 oktyabrya - uvelichivaya) sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Devy. 16 oktyabrya pri faze 0,02+ Luna pereidet v sozvezdie Vesov, a 17 oktyabrya (F= 0,1+) vstupit v sozvezdie Skorpiona. 18 oktyabrya nochnoe svetilo proidet severnee Antaresa pri faze 0,15+ (pokrytie pri vidimosti na Evropeiskoi chasti Rossii), a 19 oktyabrya pri faze 0,18+ pereidet v sozvezdie Zmeenosca. V etot zhe den' Luna (F= 0,26+) pereidet v sozvezdie Strel'ca, gde primet 22 oktyabrya fazu pervoi chetverti. V etot zhe den' lunnyi poludisk pri faze 0,5+ pereidet v sozvezdie Kozeroga. Fazy Luny na dannoe vremya i na budushee.
Iz planet Solnechnoi sistemy: Merkurii ne viden (soedinenie s Solncem 20 oktyabrya), Venera vidna na utrennem nebe v vide samoi yarkoi zvezdy, Mars mozhno naiti v luchah zahodyashego Solnca v yuzhnyh shirotah strany, a Yupiter, Saturn, Uran i Neptun nablyudayutsya v nochnoe vremya. Podrobnye efemeridy i karty dvizheniya bol'shih planet imeyutsya v Astronomicheskih kalendaryah na blizhaishie gody. Efemeridy Solnca, Luny i planet na kazhdyi den' - http://astropixels.com/.
Iz komet hvostataya strannica P/Encke (2P) dvizhetsya po sozvezdiyu Devy pri maksimal'nom bleske okolo 7m. Kometa P/Hartley (103P) dvizhetsya po sozvezdiyam Bliznecov i Raka s bleskom okolo 7m. Karty putei komet i asteroidov na mesyac imeyutsya v Kalendare nablyudatelya na blizhaishie mesyacy, a na drugie periody - v Astronomicheskih kalendaryah na blizhaishie gody.
