Astronomicheskaya nedelya s 22 po 28 marta 2021 goda19.03.2021 6:55 | Aleksandr Kozlovskii
Na dannoi nedele 22 marta Luna (F= 0,57+) proidet tochku maksimal'nogo skloneniya k severu ot nebesnogo ekvatora, a 23 marta dolgoperiodicheskaya peremennaya zvezda hi Lebedya dostignet maksimuma bleska (4m). 26 marta Luna (F= 0,9+) proidet severnee Regula, a dolgoperiodicheskaya peremennaya zvezda R Volopasa dostignet maksimuma bleska (6m). V etot zhe den' proizoidet pokrytie Lunoi (F= 0,92+) zvezdy 46 L'va (5.4m) pri vidimosti v Primor'e i na Dal'nem Vostoke, a Venera vstupit v verhnee soedinenie s Solncem. 27 marta proizoidet pokrytie Lunoi (F= 0,98+) zvezdy nyu Devy (4.0m) pri vidimosti na Evropeiskoi chasti strany, a 28 marta polnaya Luna budet nahodit'sya na nebe vsyu noch'.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 37 gradusov, a dolgota dnya na toi zhe shirote vozrastaet do 12 chasov 50 minut. Vidimyi diametr Solnca umen'shaetsya do 32,05 minut dugi, a dvizhetsya ono po sozvezdiyu Ryb. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 28 marta. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Bliznecov, Raka, L'va i Devy, izmenyaya fazu ot 0,55+ do 1,0 i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Bliznecov. 23 marta lunnyi oval dostignet sozvezdiya Raka pri faze 0,7+. Severnee zvezdnogo skopleniya Yasli (M44) yarkaya Luna (F= 0,77+) proidet 24 marta, na sleduyushii den' pereidya v sozvezdie L'va. 26 marta Luna proidet severnee Regula pri faze 0,9+, prodolzhiv put' po sozvezdiyu L'va do 27 marta, kogda pereidet v sozvezdie Devy. Zdes' 28 marta Luna primet fazu polnoluniya, i budet vidna nad gorizontom vsyu noch'. Fazy Luny na dannoe vremya i na budushee.
