Astronomicheskaya nedelya s 12 po 18 iyulya 2021 goda9.07.2021 6:01 | Aleksandr Kozlovskii
Na dannoi nedele 11 iyulya Luna (F= 0,02+) proidet severnee zvezdnogo skopleniya Yasli (M44), a 12 iyulya pri faze 0,06+ - severnee Venery i Marsa. 13 iyulya dolgoperiodicheskaya peremennaya zvezda R Kita dostignet maksimuma bleska (6,5m), Luna (F= 0,11+) proidet severnee Regula, a Venera do polgradusa sblizitsya s Marsom. 17 iyulya Luna (F= 0,48+) proidet severnee Spiki, a 18 iyulya asteroid Geba (6) vstupit v protivostoyanie s Solncem (8,4 m). Vsyu nedelyu vozmozhno poyavlenie serebristyh oblakov na fone sumerechnogo segmenta. Krome etogo, idet period, kogda yarkie sputniki Yupitera tesno sblizhayutsya i pokryvayutsya drug drugom.
Solnce. Maksimal'naya vysota dnevnogo svetila nad gorizontom na shirote Moskvy umen'shaetsya do 55 gradusov, a dolgota dnya na toi zhe shirote umen'shaetsya do 16 chasov 50 minut. Vidimyi diametr Solnca uvelichivaetsya do 31,47 minut dugi, a dvizhetsya ono po sozvezdiyu Bliznecov. Dannye o Solnce na tekushee vremya.
Luna. Estestvennyi sputnik Zemli vstupaet v fazu pervoi chetverti 17 iyulya. Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Raka, L'va, Devy, Vesov, izmenyaya fazu 0 do 0,7+, i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Raka. 13 iyulya Luna (F= 0,06+) pereidet v sozvezdie L'va, nahodyas' severnee Venery i Marsa. V etot zhe den' lunnyi serp (F= 0,11+) proidet severnee Regula, a zatem ustremitsya k sozvezdiyu Devy, v kotoroe voidet 15 iyulya pri faze 0,25+. Zdes' 17 iyulya Luna (F= 0,48+) proidet severnee Spiki, prinyav zatem fazu pervoi chetverti. Ustremivshis' k sozvezdiyu Vesov, nochnoe svetilo voidet v nego 18 iyulya pri faze 0,6+. Fazy Luny na dannoe vremya i na budushee.

Sredi asteroidov naibolee yarkoi na dannoi nedele budet Vesta (7,8m) v sozvezdii Devy.
Iz otnositel'no yarkih (do 9,0m fotograficheskogo bleska) dolgoperiodicheskih peremennyh zvezd, nablyudaemyh s territorii nashei strany, maksimuma bleska dostignut: W Andromedy 8,6m - 13 iyulya, R Kita 7,5m - 13 iyulya, Z Zmeenosca 8,1m - 18 iyulya.
