Astronomicheskaya nedelya s 18 po 24 sentyabrya 2023 goda14.09.2023 11:41 | Aleksandr Kozlovskii
Na dannoi nedele 19 sentyabrya Neptun vstupit v protivostoyanie s Solncem, a 21 sentyabrya Luna (F= 0,35+) proidet severnee Antaresa (pokrytie pri vidimosti v Primor'e i na Sahaline). 22 sentyabrya Merkurii dostignet v maksimal'noi zapadnoi (utrennei) elongacii 18 gradusov. 23 sentyabrya Luna (F= 0,53+) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora, a takzhe nastupit osennee ravnodenstvie. V etot den' v 06 chasov 50 minut po vsemirnomu vremeni Solnce, dvigayas' po ekliptike (v sozvezdii Devy), dostignet tochki nebesnoi sfery s koordinatami 12 chasov po pryamomu voshozhdeniyu i 0 gradusov po skloneniyu, peresechet nebesnyi ekvator i pereidet iz severnogo polushariya neba v yuzhnoe. V den' osennego ravnodenstviya Solnce na vsei Zemle voshodit tochno na vostoke, a zahodit tochno na zapade (den' stanovitsya raven nochi). Nastupaet astronomicheskaya osen' v severnom polusharii Zemli i vesna - v yuzhnom. Na polyusah Zemli Solnce matematicheski dvizhetsya tochno po gorizontu v techenie sutok, hotya blagodarya refrakcii, pripodnimayushei vse svetila nad gorizontom, fakticheski ono dvizhetsya vyshe gorizonta na velichinu refrakcii - okolo polgradusa. Po etoi zhe prichine vo vremya osennego (kak i vesennego) ravnodenstviya den' vse-taki nemnogo dlinnee nochi. Posle dnya osennego ravnodenstviya poludennaya vysota Solnca budet umen'shat'sya vplot' do dnya zimnego solncestoyaniya, preodolev chetvert' svoego puti po zodiakal'nym sozvezdiyam i po orbite vokrug Solnca. Krome etogo, kometa Nishimura (C/2023 P1) imeet maksimal'nyi blesk 3m, nahodyas' v sozvezdii Devy.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shitsya do 34 gradusov, a dolgota dnya na toi zhe shirote - do 12 chasov 00 minut. Vidimyi diametr Solnca uvelichivaetsya ot 31,83 do 31,89 minut dugi, a dvizhetsya ono po sozvezdiyu Devy. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 22 sentyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Devy, Vesov, Skorpiona, Zmeenosca, Strel'ca i Kozeroga, izmenyaya fazu ot 0,08+ do 0,73+ i umen'shaya (s 23 sentyabrya - uvelichivaya) sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Devy. 18 sentyabrya pri faze 0,14+ Luna pereidet v sozvezdie Vesov. 20 sentyabrya Luna (F= 0,27+) vstupit v sozvezdie Skorpiona. 21 sentyabrya nochnoe svetilo proidet severnee Antaresa pri faze 0,35+ (pokrytie pri vidimosti v Primor'e i na Sahaline), v etot zhe den' pri faze 0,39+ vstupiv v sozvezdie Zmeenosca. 22 sentyabrya Luna (F= 0,48+) pereidet v sozvezdie Strel'ca, gde primet v etot den' fazu pervoi chetverti. 24 sentyabrya Luna pri faze 0,73+ pereidet v sozvezdie Kozeroga. Fazy Luny na dannoe vremya i na budushee.
