Astronomicheskaya nedelya s 18 po 24 maya 2020 goda3.04.2020 5:55 | Aleksandr Kozlovskii
Na dannoi nedele 18 maya Luna (F= 0,17-) okazhetsya v apogee svoei orbity na rasstoyanii 405580 km ot centra Zemli, a dolgoperiodicheskaya peremennaya zvezda S Devy dostignet maksimuma bleska (6m). 20 maya Luna (F= 0,05-) proidet yuzhnee Urana, a 22 maya Merkurii proidet graduse yuzhnee Venery. V etot zhe den' Luna (F= 0,01-) proidet yuzhnee Pleyad, a 23 maya pri faze 0,01+ okazhetsya severnee Al'debarana. 24 maya dolgoperiodicheskaya peremennaya zvezda V Raka dostignet maksimuma bleska (7m), a Luna (F= 0,02+) proidet yuzhnee Venery i Merkuriya bliz voshodyashego uzla svoei orbity.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 56 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 50 minut. Vidimyi diametr Solnca umen'shaetsya do 31,57 minut dugi, a dvizhetsya ono po sozvezdiyu Tel'ca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu novoluniya 22 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Ryb, Ovna, Tel'ca i Bliznecov, izmenyaya fazu ot 0,2- do 0, a zatem do 0,05+ i uvelichivaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Kita, a 19 maya snova pereidet v sozvezdie Ryb, nablyudayas' na utrennem nebe nevysoko nad gorizontom. 20 maya Luna eshe raz posetit sozvezdie Kita, pereidya v etot zhe den' v sozvezdie Ovna, gde probudet do 21 maya, pereidya v etot den' v sozvezdie Tel'ca. V etom sozvezdii 22 maya nastupit novolunie, i Luna pereidet na vechernee nebo. Tonkii molodoi mesyac budet nablyudat'sya na fone vechernei zari, 23 maya proidya yuzhnee Merkuriya, a 24 maya - yuzhnee Venery. Fazy Luny na dannoe vremya i na budushee.
