Astronomicheskaya nedelya s 9 po 15 sentyabrya 2019 goda Astronomicheskaya nedelya s 9 po 15 sentyabrya 2019 goda
6.09.2019 5:10 | Aleksandr Kozlovskii

Na dannoi nedele 9 sentyabrya meteornyi potok Sentyabr'skie epsilon-Perseidy dostigaet maksimuma deistviya (zenitnoe chasovoe chislo meteorov - do 5), a 10 sentyabrya Neptun vstupaet v protivostoyanie s Solncem. 13 sentyabrya Luna (F= 0,99+) dostignet apogeya svoei orbity na rasstoyanii 406377 km ot centra Zemli, a Merkurii proidet v 0,3 gr. yuzhnee Venery,. V etot zhe den' Luna bliz polnoluniya proidet okolo Neptuna.

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 37 gradusov, a dolgota dnya na toi zhe shirote - do 12 chasov 50 minut. Vidimyi diametr Solnca uvelichivaetsya do 31,81 minut dugi, a dvizhetsya ono po sozvezdiyu L'va. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 14 sentyabrya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Strel'ca, Kozeroga, Vodoleya i Ryb, izmenyaya fazu ot 0,75+ do 1,0 i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Strel'ca. 9 sentyabrya Luna pereidet v sozvezdie Kozeroga faze 0,84+ Zdes' nochnoe svetilo probudet do 12 sentyabrya, pereidya v etot den' v sozvezdie Vodoleya pri faze 0,96+. Zdes' 13 sentyabrya Luna (F= 0,99+) dostignet apogeya svoei orbity na rasstoyanii 406377 km ot centra Zemli, a zatem proidet yuzhnee Neptuna pochti pri faze polnoluniya, kotoruyu primet 14 sentyabrya. V etot zhe den' polnaya Luna pereidet v sozvezdie Ryb, na sleduyushii den' dostignuv sozvezdiya Kita. Fazy Luny na dannoe vremya i na budushee.

Iz planet Solnechnoi sistemy: Merkurii i Venera vidny na fone vechernei zari v yuzhnyh raionah strany. Mars ne viden, a Yupiter i Saturn nablyudayutsya vecherom i noch'yu. Uran i Neptun nahodyatsya na nochnom nebe. Podrobnye efemeridy i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii AK_2019 na http://www.astronet.ru/db/msg/1364101 . Efemeridy planet na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ephemeris/ephemeris.html .

Iz komet hvostataya strannica Africano (C/2018 W2) dvizhetsya po sozvezdiyu Andromedy i Perseya s bleskom okolo 10m. Kometa P/SOHO (P/2008 Y12) peremeshaetsya po sozvezdiyu Vesov s bleskom okolo 8m. Karty putei komet i asteroidov na mesyac imeyutsya v KN na sentyabr', a na drugie periody - v Astronomicheskom kalendare na 2019 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 na dannoi nedele budut: Evnomiya (8,6m) v sozvezdii Vodoleya i Vesta (7,5m) 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 Kassiopei 7,9m - 9 sentyabrya, X Zhirafa 8,1m - 9 sentyabrya, RS Bol'shoi Medvedicy 9,0m - 12 sentyabrya, R Kita 8,1m - 15 sentyabrya, RZ Pegasa 8,8m - 15 sentyabrya.

Nekotorye blizkie pary svetil: Luna - Saturn, Luna - Neptun, Merkurii - Venera, Mars - Regul, Yupiter - Antares, Saturn - omikron Strel'ca, Uran - al'fa Ovna, Neptun - fi Vodoleya, Africano (C/2018 W2) - al'fa Perseya, P/SOHO (P/2008 Y12) ipsilon Vesov.

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: 9 sentyabrya - v 1904 godu, 10 sentyabrya - 1923 godu, 11 sentyabrya - v 1029 godu, 12 sentyabrya - v 1950 godu, 13 sentyabrya - v 1178 godu, 14 sentyabrya - v 1708 godu, 15 sentyabrya - v 1746 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 13 sentyabrya (7 zatmenii), a men'she vsego - 14 sentyabrya (2 zatmeniya). Your Guide to the 2017 Total Solar Eclipse
