Astronomicheskaya nedelya s 4 po 10 maya 2020 goda Astronomicheskaya nedelya s 4 po 10 maya 2020 goda
1.04.2020 10:49 | Aleksandr Kozlovskii

Na dannoi nedele 4 maya Merkurii okazhetsya v verhnem soedinenii s Solncem, 5 maya Luna (F= 0,96+) proidet severnee Spiki, a dolgoperiodicheskaya peremennaya zvezda RS Gerkulesa dostignet maksimuma bleska (7m). V etot zhe den' nastupit maksimum deistviya meteornogo potoka eta-Akvaridy (ZHR= 40), a 6 maya Luna (F= 0,97+) dostignet perigeya svoei orbity na rasstoyanii 359655 km ot centra Zemli. 8 maya Luna (F= 0,97-) proidet severnee Antaresa, a 10 maya pri faze 0,89- dostignet nishodyashego uzla svoei orbity. V etot zhe den' dolgoperiodicheskaya peremennaya zvezda W Andromedy dostignet maksimuma bleska (7m).

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 52 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 00 minut. Vidimyi diametr Solnca umen'shaetsya do 31,67 minut dugi, a dvizhetsya ono po sozvezdiyu Ovna. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 7 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Devy, Vesov, Skorpiona, Zmeenosca i Strel'ca, izmenyaya fazu ot 0,8+ do 1, a zatem do 0,8- i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Devy. Zdes' Luna probudet do 6 maya, proidya 5 maya severnee zvezdy Spika (glavnoi zvezdy sozvezdiya). 7 maya v sozvezdii Vesov nastupit polnolunie i yarkii lunnyi disk budet nablyudat'sya vsyu noch' nevysoko nad gorizontom. 8 maya polnaya Luna posetit sozvezdie Skorpiona i v etot zhe den' voidet v sozvezdie Zmeenosca, gde proidet severnee Antaresa i probudet zdes' do 10 maya. V etot den' Luna pri faze okolo 0,9- pereidet v sozvezdie Strel'ca, v kotorom zaderzhitsya do 12 maya Fazy Luny na dannoe vremya i na budushee.

Iz planet Solnechnoi sistemy: Merkurii nachinaet vechernyuyu vidimost', a Venera vidna neskol'ko chasov posle zahoda Solnca. Mars, Yupiter, Saturn, Uran i Neptun nahodyatsya na utrennem nebe. Podrobnye efemeridy i karty dvizheniya bol'shih planet dayutsya v pechatnoi versii AK_2020 na http://www.astronet.ru/db/msg/1364099 . Efemeridy Solnca, Luny i planet na kazhdyi den' imeyutsya takzhe na http://astropixels.com/ .

Iz komet hvostatye strannicy PANSTARRS (C/2017 T2) i ATLAS (C/2019 Y1) peremeshayutsya po sozvezdiyu Zhirafa s bleskom okolo 9m. ATLAS (C/2019 Y4) dvizhetsya po sozvezdiyu Zhirafa pri bleske okolo 10m. Kometa SWAN (C/2020 F8) peremeshaetsya po sozvezdiyam Kita i Ryb pri bleske 7m. Karty putei komet i asteroidov na mesyac imeyutsya v KN na mai, a na drugie periody - v Astronomicheskom kalendare na 2020 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 (8,5m) 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 Pegasa 8,9m - 4 maya, RS Gerkulesa 7,9m - 5 maya, W Andromedy 7,4m - 10 maya.

Nekotorye blizkie pary svetil: Luna - Spika, Luna - Antares, Luna Yupiter. Yupiter - Saturn, Uran - al'fa Ovna, Neptun - fi Vodoleya, Vesta - Giady, Venera - Giady, komety PANSTARRS (C/2017 T2) i ATLAS (C/2019 Y1).

Obzor tumannyh nebesnyh ob'ektov mesyaca - v zhurnale Nebosvod . Videokalendar' predstoyashih yavlenii http://www.youtube.com/user/AstroSmit i http://www.youtube.com/c/AstroMich .

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!
