Astronomicheskaya nedelya s 27 maya po 2 iyunya 2019 goda Astronomicheskaya nedelya s 27 maya po 2 iyunya 2019 goda
11.04.2019 16:16 | Aleksandr Kozlovskii

Na dannoi nedele 27 maya - Luna (F= 0,4-) bliz Neptuna, 29 maya - Cerera (1) v protivostoyanii s Solncem, 31 maya - Luna (F= 0,2-) bliz Urana, 1 iyunya - Luna (F= 0,03-) bliz Venery, 2 iyunya - dolgoperiodicheskaya peremennaya zvezda T Gerkulesa bliz maksimuma bleska (7m). Krome etogo, prodolzhaetsya period poyavleniya serebristyh oblakov na fone sumerechnogo segmenta v srednih shirotah strany.

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 56 gradusov, a dolgota dnya na toi zhe shirote - do 17 chasov 10 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shaetsya do 31,55 minut dugi, a dvizhetsya ono po sozvezdiyu Tel'ca. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 3 iyunya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Vodoleya, Ryb, Ovna, Tel'ca, izmenyaya fazu ot 0,5- do 0 i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Vodoleya. 27 maya lunnyi serp pri faze 0,4- proidet bliz Neptuna, a 28 maya pri faze 0,33- pereidet v sozvezdie Ryb. Prodolzhaya umen'shat' fazu, stareyushii mesyac 29 maya vstupit v sozvezdie Kita pri faze 0,27-, a 30 maya (F= 0,17-) vnov' peresechet granicu s sozvezdiem Ryb. 31 maya Luna eshe raz zaidet v sozvezdie Kita, pri faze 0,1- proidet yuzhnee Urana i zakonchit svoi put' po maiskomu nebu pri faze 0,07- okolo granicy s sozvezdiem Ovna. V pervyi den' leta Luna pereidet v sozvezdie Ovna, a k koncu etogo dnya dostignet sozvezdiya Tel'ca pri faze 0,03-, proidya yuzhnee Venery. Zdes' tonchaishii serp 3 iyunya sblizitsya s Al'debaranom i primet fazu novoluniya. Fazy Luny na dannoe vremya i na budushee.

Iz planet Solnechnoi sistemy: Merkurii viden v luchah zahodyashego Solnca. Venera nablyudaetsya v luchah voshodyashego Solnca v yuzhnyh shirotah strany, Yupiter i Saturn vidny na nochnom i utrennem nebe, a Mars - na fone vechernei zari. Uran i Neptun nahodyatsya na utrennem 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 Iwamoto (C/2018 Y1) peremeshaetsya po sozvezdiyu Perseya s bleskom slabee 12m, yavlyayas' nezahodyashim svetilom v severnyh raionah strany. Karty putei komet i asteroidov na mesyac imeyutsya v KN na mai, KN na iyun', 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: Cerera (7,0m) v sozvezdiyah Zmeenosca i Skorpiona, Vesta (8,3m) v sozvezdii Ryb i Pallada (8,8m) v sozvezdii Volos Veroniki.

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignet T Gerkulesa 8,0m - 2 iyunya.

Nekotorye blizkie pary svetil: Luna - Neptun, Luna - Venera, Luna - Uran, Luna - Al'debaran, Yupiter - Antares, Saturn - omikron Strel'ca, Uran - omikron Ryb, Neptun - lyambda Vodoleya, Pallada - Arktur, Flora - Partenopa.

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: 27 maya - v 1435 godu, 28 maya - 1900, 29 maya - v 1938 godu, 30 maya - v 1965 godu, 31 maya - v 1090 godu, 1 iyunya - v 0672 godu, 2 iyunya - v 1220 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 29 maya (9 zatmenii), a men'she vsego - 2 iyunya (2 zatmeniya). Your Guide to the 2017 Total Solar Eclipse
