Astronomicheskaya nedelya s 17 po 23 sentyabrya 2018 goda Astronomicheskaya nedelya s 17 po 23 sentyabrya 2018 goda
14.09.2018 6:01 | Aleksandr Kozlovskii

Na dannoi nedele 17 sentyabrya Luna (F= 0,57+) proidet severnee Saturna, a na sleduyushii den' pri faze 0,64+ dostignet tochki maksimal'nogo skloneniya k yugu ot nebesnogo ekvator. 18 sentyabrya proizoidet pokrytie Lunoi (F= 0,67+) zvezdy omikron Strel'ca (3,8m) pri vidimosti na Evropeiskoi chasti Rossii, a na sleduyushii den' asteroid Uraniya (30) vstupit v protivostoyanie s Solncem. V seredine nedeli dolgoperiodicheskaya peremennaya zvezda R Rysi dostignet maksimuma bleska (6,5m), a Luna (F= 0,78+) proidet apogei svoei orbity na rasstoyanii 404875 km ot centra Zemli bliz nishodyashego uzla svoei orbity i okolo Marsa. 21 sentyabrya dolgoperiodicheskaya peremennaya zvezda R Gidry dostignet maksimuma bleska (3,5m), a Merkurii okazhetsya v verhnem soedinenii s Solncem. 23 sentyabrya nastupit osennee ravnodenstvie, a Luna (F= 0,97+) proidet yuzhnee Neptuna. Krome etogo, prodolzhaetsya sezon serebristyh oblakov, kotorye poyavlyayutsya na fone vechernih i utrennih sumerek, a kometa P/Giacobini-Zinner (21P) imeet blesk yarche 8m i dostatochno blagopriyatnye usloviya nablyudenii na territorii nashei strany.

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 34 gradusov, a dolgota dnya na toi zhe shirote - do 12 chasov 00 minut. Vidimyi diametr Solnca za opisyvaemyi period uvelichivaetsya do 31,87 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 polnoluniya 25 sentyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Zmeenosca, Strel'ca, Kozeroga, Vodoleya, izmenyaya fazu ot 0,5+ do 1,0 i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Zmeenosca, pereidya v pervyi den' nedeli pri faze 0,52+ v sozvezdie Strel'ca. Luna sovershit po nemu pochti trehdnevnoe puteshestvie, proidya v nachale etogo puti severnee Saturna (bliz maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora). V sozvezdie Kozeroga Luna voidet pri faze 0,77+ v samom konce dnya 19 sentyabrya, proidya na sleduyushii den' severnee Marsa (F= 0,8+) bliz nishodyashego uzla i apogeya svoei orbity. V sozvezdie Vodoleya yarkaya Luna (F= 0,93+) pereidet 22 sentyabrya, a na sleduyushii den' pri faze 0,97+ proidet yuzhnee Neptuna. Fazy Luny na dannoe vremya i na budushee.

Iz planet Solnechnoi sistemy: Merkurii ne viden, a Venera nablyudaetsya na fone vechernei zari (vidna takzhe i dnem). Mars, Saturn i Yupiter mozhno nablyudat' v vechernie chasy, a Uran i Neptun vidny vsyu noch'. Podrobnye efemeridy i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii AK_2018 na http://www.astronet.ru/db/msg/1364103. Efemeridy planet na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ephemeris/ephemeris.html .

Iz komet hvostataya strannica P/Giacobini-Zinner (21P) dvizhetsya po sozvezdiyu Bliznecov i Oriona, imeya blesk yarche 8m. Karty putei komet i asteroidov na mesyac imeyutsya v KN na sentyabr', a na drugie periody - v Astronomicheskom kalendare na 2018 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 yarkimi i udobnymi dlya nablyudenii na dannoi nedele budut: Vesta (7,2m) v sozvezdii Strel'ca i Yunona (8,3m) v sozvezdii Tel'ca.

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: T Andromedy 8,5m - 17 sentyabrya, SS Zmeenosca 8,7m - 18 sentyabrya, R Rysi 7,9m - 20 sentyabrya, T Gidry 7,8m - 21 sentyabrya, R Gidry 4,5m - 21 sentyabrya, S Zmei 8,7m - 21 sentyabrya, W Raka 8,2m - 22 sentyabrya, R Yashericy 9,1m - 23 sentyabrya.

Nekotorye blizkie pary svetil: Luna - Saturn, Luna - Neptun, Venera - Spika, Saturn - M21, Vesta - teta Zmeenosca, Yupiter - al'fa Vesov, Uran - omikron Ryb, Neptun - lyambda Vodoleya.

Nedel'nyi obzor ot zhurnala "Skai end Teleskop", no nuzhno uchityvat', chto kartinki dayutsya dlya 40 severnoi shiroty, a polozhenie Luny i planet na 7 chasov pozdnee otnositel'no moskovskogo vremeni!

Yasnogo neba i uspeshnyh nablyudenii!

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 17 sentyabrya - v 1876 godu, 18 sentyabrya - v 1400 godu, 19 sentyabrya - v 1419 godu, 20 sentyabrya - v 1001 godu, 21 sentyabrya - v 1941 godu, 22 sentyabrya - v 1968 godu, 23 sentyabrya - v 1699 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 17, 21 i 22 sentyabrya (po 6 zatmenii !), a men'she vsego 19 sentyabrya (1 zatmenie).
