Astronomicheskaya nedelya s 3 po 9 iyulya 2023 goda30.06.2023 12:18 | Aleksandr Kozlovskii
Na dannoi nedele 3 iyulya Luna (F= 0,99+) proidet tochku maksimal'nogo skloneniya k yugu ot nebesnogo ekvatora. 4 iyulya Luna (F= 0,97-) dostignet perigeya svoei orbity na rasstoyanii 360151 km ot centra Zemli. 6 iyulya Zemlya proidet afelii svoei orbity na rasstoyanii 1,0166806 a.e. ot Solnca, a 7 iyulya Luna (F= 0,81-) proidet yuzhnee Saturna. 8 iyulya asteroid Evnomiya (15) vstupit v protivostoyanie s Solncem, a Luna (F= 0,67-) proidet yuzhnee Neptuna. Krome etogo, ves' mesyac imeetsya vozmozhnost' poyavleniya serebristyh oblakov na fone vechernei i utrennei zari.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shitsya do 56 gradusov, a dolgota dnya na toi zhe shirote - do 17 chasov 10 minut. Vidimyi diametr Solnca priderzhivaetsya znacheniya 31,46 minut dugi, a dvizhetsya ono po sozvezdiyu Bliznecov. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 3 iyulya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Strel'ca, Kozeroga, Vodoleya i Ryb, izmenyaya fazu ot 0,99+ do 0,51- i umen'shaya (s 3 iyulya - uvelichivaya) sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Strel'ca. V etom sozvezdii Luna primet fazu polnoluniya 3 iyulya, a 4 iyulya pri faze 0,98- pereidet v sozvezdie Kozeroga, nablyudayas' vsyu korotkuyu noch'. 6 iyulya Luna pereidet v sozvezdie Vodoleya, umen'shiv fazu do 0,87-. Na sleduyushii den' nochnoe svetilo pri faze 0,81- proidet yuzhnee Saturna. 8 iyulya lunnyi oval pri faze 0,67- proidet yuzhnee Neptuna, a pri faze 0,66- pereidet v sozvezdie Ryb. Na sleduyushii den' Luna (F= 0,59-) pereidet v sozvezdie Kita, a pri faze 0,54- snova vozvratitsya v sozvezdie Ryb. Zdes' nochnoe svetilo primet fazu poslednei chetverti 10 iyulya. Fazy Luny na dannoe vremya i na budushee.
