Astronomicheskaya nedelya s 13 po 19 maya 2019 goda10.04.2019 7:40 | Aleksandr Kozlovskii
Na dannoi nedele 13 maya Luna (F= 0,71+) okazhetsya v perigee svoei orbity na rasstoyanii 369012 km ot centra Zemli, a na sleduyushii den' dolgoperiodicheskaya peremennaya zvezda V Edinoroga dostignet maksimuma bleska (6m). 15 maya asteroid Partenopa (11) vstupit v protivostoyanie s Solncem, a na sleduyushii den' dolgoperiodicheskaya peremennaya zvezda R Volopasa dostignet maksimuma bleska (6m), 18 maya Venera proidet v graduse yuzhnee Urana. Krome etogo, nastupaet period poyavleniya serebristyh oblakov na fone sumerechnogo segmenta v srednih shirotah strany, a Mars v konce nedeli peresekaet rasseyannoe zvezdnoe skoplenie M35 v sozvezdii Bliznecov.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 54 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 30 minut. Vidimyi diametr Solnca za opisyvaemyi period umen'shaetsya do 31,62 minut dugi, a dvizhetsya ono po sozvezdiyu Ovna, 14 maya perehodya v sozvezdie Tel'ca. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 18 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya L'va, Devy, Vesov, Skorpiona i Zmeenosca, izmenyaya fazu ot 0,6+ do 1,0 i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii L'va. Perigeya svoei orbity Luna dostignet 13 maya pri faze 0,71+. Granicy s sozvezdiem Devy Luna dostignet 14 maya pri faze 0,74+. Zdes' 16 maya Luna (F= 0,91+) proidet v 7,5 gradusah severnee Spiki. 18 maya pri faze 0,97- Luna pereidet v sozvezdie Vesov i primet v etot den' fazu polnoluniya. V sozvezdii Vesov yarkii lunnyi disk probudet do 19 maya, umen'shiv fazu do 0,99- i pereidya v sozvezdie Skorpiona. V etot zhe den' yarkaya Luna (F= 0,99-) pereidet v sozvezdie pereidet Zmeenosca, nablyudayas' na nochnom nebe nizko nad gorizontom. Fazy Luny na dannoe vremya i na budushee.
