Astronomicheskaya nedelya s 28 maya po 3 iyunya 2018 goda Astronomicheskaya nedelya s 28 maya po 3 iyunya 2018 goda
17.05.2018 19:02 | Aleksandr Kozlovskii

Na dannoi nedele dolgoperiodicheskie peremennye zvezdy RT Lebedya (6m) i R Zmeenosca (6,5m) dostigayut maksimuma bleska, 1 iyunya Luna (F= 0,95-) prohodit severnee Saturna okolo maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora, 2 iyunya Luna (F= 0,85-) dostignet apogeya svoei orbity na rasstoyanii 405310 km ot centra Zemli, 3 iyunya Luna (F= 0,8-) prohodit severnee Marsa okolo nishodyashego uzla svoei orbity, a Merkurii prohodit v 6 gradusah severnee Al'debarana. Krome etogo, prodolzhaetsya sezon serebristyh oblakov, kotorye poyavlyayutsya na fone vechernih i utrennih sumerek. Vesta imeet 6 zvezdnuyu velichinu i mozhet byt' naidena nevooruzhennym glazom pri blagopriyatnyh usloviyah.

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 15 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shitsya do 31,54 minut dugi, a dvizhetsya ono po sozvezdiyu Tel'ca. Dannye o Solnce na tekushee vremya.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 29 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Vesov, Skorpiona, Zmeenosca, Strel'ca i Kozeroga, izmenyaya fazu ot 1 do 0,75 i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii do serediny nedeli (zatem uvelichivaya). Nachalo nedeli nochnoe svetilo provedet v sozvezdii Vesov bliz Yupitera. 29 maya Luna pereidet v sozvezdie Skorpiona, gde primet fazu polnoluniya. V etot zhe den' yarkii lunnyi disk peresechet granicu s sozvezdiem Zmeenosca, i budet nablyudat'sya nizko nad gorizontom vsyu korotkuyu noch'. 31 maya Luna pereidet v sozvezdie Strel'ca i zakonchit zdes' put' po vesennemu nebu pri faze 0,95- severnee Saturna i bliz maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora. Pereidya na letnee nebo i prodolzhaya put' po sozvezdiyu Strel'ca, yarkii lunnyi disk bliz apogeya svoei orbity vstupit v sozvezdie Kozeroga 2 iyunya, umen'shiv fazu do 0,83. Severnee Marsa lunnyi oval proidet 3 iyunya uzhe pri faze 0,8-. Faza Luny na dannoe vremya i na budushee.

Iz planet Solnechnoi sistemy: Venera yarko siyaet na fone vechernei zari. Merkurii ne viden. Mars i Saturn vidny noch'yu i utrom, Yupiter nablyudaetsya vsyu noch', a Uran i Neptun mozhno naiti na utrennem nebe. 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) nahoditsya v sozvezdii Lebedya, imeya blesk slabee 12m. Kometa PANSTARRS (C/2016 M1) dvizhetsya po sozvezdiyu Strel'ca pri bleske okolo 10m. Karty putei komet i asteroidov na mesyac imeyutsya v KN na mai, i KN na iyun', 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: Cerera (8,7m) v sozvezdii L'va i Vesta (5,7m) v sozvezdii Strel'ca. Vestu pri blagopriyatnyh usloviyah mozhno naiti nevooruzhennym glazom.

Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd (po dannym AAVSO), nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: RT Lebedya 7,3m - 29 maya, W Liry 7,9m - 30 maya, RY Zmeenosca 8,2m - 30 maya, R Zmeenosca 7,6m - 31 maya, U Mikroskopa 8,8m - 31 maya, Y Edinoroga 9,1m - 3 iyunya.

Nekotorye blizkie pary svetil: Luna - Yupiter, Luna - Antares, Luna - Saturn, Luna - Mars, Merkurii - Al'debaran, Mars - Saturn, Saturn - Vesta, Saturn - M22, Vesta - M24, Venera Polluks, Yupiter - al'fa Vesov, Uran - omikron Ryb, Neptun - lyambda Vodoleya.

Yasnogo neba i uspeshnyh nablyudenii!

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 28 maya - v 1900 godu, 29 maya - v 1938 godu, 30 maya - v 1965 godu, 31 maya - v 1090 godu, 01 iyunya - v 0672 godu, 02 iyunya - v 1220 godu, 03 iyunya - v 1742 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
