V etot zhe den' Venera dostignet stoyaniya s perehodom k popyatnomu dvizheniyu. 21 iyulya Luna (F= 0,11+) proidet severnee Marsa. 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 54 gradusov, a dolgota dnya na toi zhe shirote - do 16 chasov 30 minut.

Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Bliznecov, Raka, L'va i Devy, izmenyaya fazu ot 0,01- do 0,31+ i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Bliznecov. Zdes' 17 iyulya Luna primet fazu novoluniya. V etot zhe den' molodoi mesyac pereidet v sozvezdie Raka, gde 18 iyulya (F= 0,01+) proidet severnee rasseyannogo zvezdnogo skopleniya Yasli (M44). 19 iyulya Luna (F= 0,03+) proidet severnee Merkuriya, a zatem vstupit v sozvezdie L'va, gde 20 iyulya pri faze 0,07+ proidet severnee Venery i Regula. 21 iyulya lunnyi serp (F= 0,11+) proidet severnee Marsa, a zatem ustremitsya k sozvezdiyu Devy, v kotoroe voidet 22 iyulya pri faze 0,2+. Fazy Luny na dannoe vremya i na budushee.
