Astronomicheskaya nedelya s 13 po 19 sentyabrya 2021 goda10.09.2021 7:01 | Aleksandr Kozlovskii
Na dannoi nedele 13 sentyabrya Luna (F= 0,4+) proidet severnee Antaresa. 14 sentyabrya Merkurii dostignet maksimal'noi vostochnoi (vechernei) elongacii 27 gradusov, a Neptun vstupit v protivostoyanie s Solncem. 15 sentyabrya Luna (F= 0,64+) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora. 17 sentyabrya Luna (F= 0,83+) proidet yuzhnee Saturna, a takzhe proizoidet pokrytie Lunoi (F= 0,89+) zvezdy 33 Kozeroga (5,4m) pri vidimosti na Evropeiskoi chasti strany. 18 sentyabrya Luna (F= 0,92+) proidet yuzhnee Yupitera, a 19 sentyabrya dolgoperiodicheskaya peremennaya zvezda R Rysi dostignet maksimuma bleska (7m). Prodolzhaetsya period, kogda yarkie sputniki Yupitera tesno sblizhayutsya i pokryvayutsya drug drugom.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 35 gradusov, a dolgota dnya na toi zhe shirote - do 12 chasov 25 minut. Vidimyi diametr Solnca uvelichivaetsya do 31,84 minut dugi, a dvizhetsya ono po sozvezdiyu L'va, 17 sentyabrya perehodya v sozvezdie Devy. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 13 sentyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Zmeenosca, Strel'ca, Kozeroga i Vodoleya, izmenyaya fazu ot 0,4+ do 1,0 i uvelichivaya sklonenie (s 15 sentyabrya), a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Zmeenosca, nablyudayas' severnee Antaresa. Zdes' Luna primet fazu pervoi chetverti 13 sentyabrya, a na sleduyushii den' pereidet v sozvezdie Strel'ca uzhe pri faze 0,55+. Nochnoe svetilo probudet zdes' do 16 sentyabrya, a zatem (F= 0,79+) pereidet v sozvezdie Kozeroga, gde proidet yuzhnee Saturna 17 sentyabrya pri faze 0,83+. 18 sentyabrya Luna (F= 0,92+) proidet yuzhnee Yupitera, a zatem voidet v sozvezdie Vodoleya, uvelichiv fazu do 0,93+. Fazy Luny na dannoe vremya i na budushee.

Karty putei komet i asteroidov na mesyac imeyutsya v KN na sentyabr', a na drugie periody - v Astronomicheskom kalendare na 2021 god. Podrobnye svedeniya o kometah nedeli i mesyaca (s kartami i prognozami bleska) privodyatsya na http://aerith.net/comet/weekly/current.html , a rezul'taty nablyudenii - na http://195.209.248.207/ .
Sredi asteroidov naibolee yarkoi na dannoi nedele budet Vesta (7,9m) v sozvezdii Devy.
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: R Rysi 7,9m - 19 sentyabrya i X Kita 9,0m - 19 sentyabrya.
