Astronomicheskaya nedelya s 6 po 12 maya 2019 goda8.04.2019 5:10 | Aleksandr Kozlovskii
Na dannoi nedele 6 maya proizoidet pokrytie Lunoi (0,03+) zvezdy del'ta1 Tel'ca (3,8m) pri vidimosti na Evropeiskoi chasti Rossii. V etot zhe den' Luna (F= 0,04+) proidet bliz Al'debarana, a takzhe nastupit maksimum deistviya meteornogo potoka eta-Akvaridy s chasovym zenitnym chislom meteorov 40. 7 maya Luna (F= 0,1+) budet nahodit'sya bliz Marsa, a na sleduyushii den' Merkurii proidet v 1,3 gradusa yuzhnee Urana. 9 maya Luna (F= 0,2+) proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora, a dolgoperiodicheskaya peremennaya zvezda R Malogo L'va dostignet maksimuma bleska (6m). V etot zhe den' Luna (F= 0,25+) okazhetsya v voshodyashem uzle svoei orbity, a dolgoperiodicheskaya peremennaya zvezda S Devy dostignet maksimuma bleska (6m). 11 maya Luna (F= 0,39+) proidet cherez zvezdnoe skoplenie Yasli (M44), a 12 maya Luna (F= 0,57+) budet nahodit'sya bliz Regula. V etot zhe den' asteroid Flora (8) vstupit v protivostoyanie s Solncem, a takzhe proizoidet pokrytie Lunoi (0,58+) zvezdy 37 L'va (5,4m) pri vidimosti na Evropeiskoi chasti Rossii.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 53 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 00 minut. Vidimyi diametr Solnca za opisyvaemyi period 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 pervoi chetverti 12 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Tel'ca, Bliznecov, Raka, L'va, izmenyaya fazu ot 0,0 do 0,6+ i uvelichivaya sklonenie (do serediny nedeli, a zatem umen'shaya), a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Tel'ca. Zdes' tonkii serp pri faze 0,04+ proidet v 2 gradusah severnee Al'debarana 6 maya, a 7 maya okazhetsya v 3 gradusah yuzhnee Marsa. Tekushaya seriya pokrytii Al'debarana zakonchilas', a v sleduyushii raz Luna pokroet etu zvezdu tol'ko 18 avgusta 2033 goda. Prodolzhaya dvizhenie po sozvezdiyu Tel'ca, Luna dostignet sozvezdiya Oriona pri faze 0,12+ 8 maya, v etot zhe den' pereidya v sozvezdie Bliznecov, nahodyas' bliz maksimal'nogo skloneniya k severu ot nebesnogo ekvatora. Zdes' Luna (F= 0,25+) proidet voshodyashii uzel svoei orbity. Blagopoluchno minovav sozvezdie Bliznecov, rastushii serp dostignet sozvezdiya Raka pri faze 0,32+ 10 maya, gde na sleduyushii den' peresechet zvezdnoe skoplenie Yasli (M44) pri faze 0,39+. 11 maya Luna (F= 0,47+) pereidet v sozvezdie L'va. V etom sozvezdii nochnoe svetilo primet fazu pervoi chetverti 12 maya, v etot zhe den' proidya v 3 gradusah severnee Regula pri faze 0,57+. Fazy Luny na dannoe vremya i na budushee.

Eto interesno! Predydushee polnoe solnechnoe zatmenie imelo mesto: 6 maya - v 1883 godu, 7 maya - v 1529 godu, 8 maya - v 1510 godu, 9 maya - v 1929 godu, 10 maya - v 1575 godu, 11 maya - v 1687 godu, 12 maya - v 1706 godu. Bol'she vsego (za proshedshie dve tysyachi let) polnyh zatmenii v eti dni bylo 10 maya (7 zatmenii), a men'she vsego - 7 maya (2 zatmeniya). Your Guide to the 2017 Total Solar Eclipse
