Astronomicheskaya nedelya s 11 po 17 aprelya 2022 goda8.04.2022 8:02 | Aleksandr Kozlovskii
Na dannoi nedele 12 aprelya proizoidet pokrytie Lunoi (F= 0,79+) zvezdy eta L'va (3,5m) pri vidimosti v Sibiri i na vostoke strany, a asteroid Flora (8) vstupit v protivostoyanie s Solncem. V etot zhe den' Yupiter proidet v 0,1 gr. k severu ot Neptuna, a Luna (F= 0,8+) - severnee Regula. 13 aprelya Luna dostignet maksimal'noi zapadnoi libracii po dolgote 6 gradusov. 15 aprelya proizoidet pokrytie Lunoi (F= 0,98+) zvezdy gamma Devy (2,8m) pri vidimosti v vostochnoi polovine strany, a 16 aprelya Luna (F= 1,0) proidet severnee Spiki. 17 aprelya Merkurii sblizitsya s Uranom do 2 gradusov. Na utrennem nebe nablyudaetsya parad planet, kotoryi luchshe vsego viden v yuzhnyh shirotah.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy uvelichivaetsya do 44 gradusov, a dolgota dnya na toi zhe shirote - do 14 chasov 20 minut. Vidimyi diametr Solnca umen'shaetsya do 31,87 minut dugi, a dvizhetsya ono po sozvezdiyu Ryb. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu polnoluniya 16 aprelya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Raka, L'va, Devy i Vesov izmenyaya fazu ot 0,65+ do 0,98- i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Raka. V sozvezdie L'va nochnoe svetilo vstupit 11 aprelya pri faze 0,71+, gde 12 aprelya proidet severnee Regula pri faze 0,8+. Zatem yarkii lunnyi disk ustremitsya k sozvezdiyu Devy, v kotoroe voidet pri faze 0,92+ 14 aprelya. Zdes' 16 aprelya Luna primet fazu polnoluniya (nablyudayas' vsyu noch') i prodolzhit dvizhenie po sozvezdiyu Devy v napravlenii Spiki, severnee kotoroi proidet v etot zhe den'. 17 aprelya lunnyi disk (F= 0,99-) pereidet v sozvezdie Vesov i probudet zdes' do 19 aprelya. Fazy Luny na dannoe vremya i na budushee.
