Astronomicheskaya nedelya s 8 po 14 maya 2023 goda5.05.2023 17:41 | Aleksandr Kozlovskii
Na dannoi nedele 9 maya Luna (F= 0,85-) prohodit tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora, a Uran vstupit v soedinenie s Solncem. 11 maya Luna (F= 0,66-) dostignet perigeya svoei orbity na rasstoyanii 369345 km ot centra Zemli, a 13 maya pri faze 0,4- proidet yuzhnee Saturna. 14 maya Merkurii dostignet stoyaniya s perehodom k pryamomu dvizheniyu.

Vidimyi diametr Solnca umen'shaetsya ot 31,71 do 31,65 minut dugi, a dvizhetsya ono po sozvezdiyu Ovna. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu poslednei chetverti 12 maya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Zmeenosca, Strel'ca, Kozeroga i Vodoleya, izmenyaya fazu ot 0,94- do 0,24- i umen'shaya (s 9 maya - uvelichivaya) sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Zmeenosca. Na sleduyushii den' Luna (F= 0,89-) pereidet v sozvezdie Strel'ca. V etom sozvezdii Luna probudet do 10 maya, kogda pri faze 0,68- pereidet v sozvezdie Kozeroga. Zdes' 12 maya Luna primet fazu poslednei chetverti, v etot zhe den' pereidya v sozvezdie Vodoleya. 13 maya lunnyi serp pri faze 0,4- proidet yuzhnee Saturna, a 15 maya pri faze 0,24- - yuzhnee Neptuna. Fazy Luny na dannoe vremya i na budushee.
