Astronomicheskaya nedelya s 25 po 31 maya 2020 goda Astronomicheskaya nedelya s 25 po 31 maya 2020 goda
22.05.2020 6:01 | Aleksandr Kozlovskii

Na dannoi nedele 25 maya Luna (F= 0,10+) proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora, a 26 maya dolgoperiodicheskaya peremennaya zvezda R Zmei dostignet maksimuma bleska (6m). 28 maya Luna (F= 0,26+) proidet severnee zvezdnogo skopleniya Yasli (M44), a 29 maya pri faze 0,42+ - severnee Regula. Krome etogo, vsyu nedelyu na fone vechernih i utrennih sumerek vozmozhno poyavlenie serebristyh oblakov.

Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy sostavlyaet okolo 56 gradusov, a dolgota dnya na toi zhe shirote - 17 chasov 05 minut. Vidimyi diametr Solnca 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 pervoi chetverti 30 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Bliznecov, Raka, L'va i Devy. izmenyaya fazu ot 0,05+ do 0,6+ i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Bliznecov i budet nablyudat'sya na vechernem nebe vysoko nad zapadnym gorizontom. 27 maya Luna pereidet v sozvezdie Raka, gde v etot den' proidet severnee rasseyannogo zvezdnogo skopleniya Yasli (M44). 28 maya lunnyi serp pereidet v sozvezdie L'va, gde 29 maya proidet severnee Regula, imeya vid pochti poludiska. 30 maya Luna v sozvezdii L'va primet fazu pervoi chetverti i zakonchit svoi put' po vesennemu nebu v sozvezdii Devy. Fazy Luny na dannoe vremya i na budushee.
