Astronomicheskaya nedelya s 1 po 7 maya 2023 goda28.04.2023 13:46 | Aleksandr Kozlovskii
Na dannoi nedele 1 maya Merkurii vstupit v nizhnee soedinenie s Solncem. 4 maya Luna (F= 0,97+) proidet severnee Spiki, a pri faze 0,99+ okazhetsya v nishodyashem uzle svoei orbity, 5 maya proizoidet polutenevoe lunnoe zatmenie (vidimost' na territorii nashei strany, a 6 maya meteornyi potok eta-Akvaridy (ZHR= 40) iz sozvezdiya Vodoleya budet nahodit'sya bliz maksimuma deistviya. 7 maya - Luna (F= 0,96-) proidet severnee Antaresa.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya ot 49 do 51 gradusa, a dolgota dnya na toi zhe shirote - do 15 chasov 45 minut.

Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 5 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya L'va, Devy, Vesov, Skorpiona i Zmeenosca, izmenyaya fazu ot 0,78+ do 0,94- i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii L'va. 1 maya yarkaya Luna (F= 0,83+) pereidet v sozvezdie Devy. Zdes' 4 maya Luna pri faze 0,97+ proidet severnee Spiki. Zatem lunnyi disk ustremitsya k sozvezdiyu Vesov, v kotoroe voidet 5 maya pri faze 0,99+. Zdes' nochnoe svetilo primet fazu polnoluniya 5 maya. V dannoe polnolunie proizoidet polutenevoe lunnoe zatmenie, vidimoe na territorii nashei strany. 6 maya yarkii lunnyi disk pri faze 0,98- vstupit v sozvezdie Skorpiona, a 7 maya (F= 0,96-) proidet severnee Antaresa, v etot zhe den' vstupiv v sozvezdie Zmeenosca pri faze 0,94-. Fazy Luny na dannoe vremya i na budushee.
