Na dannoi nedele 14 avgusta Luna (F= 0,02-) proidet severnee rasseyannogo zvezdnogo skopleniya Yasli (M44), a 15 avgusta pri faze 0,01- - severnee Venery, 16 avgusta Luna (F= 0,01+) dostignet apogeya svoei orbity na rasstoyanii 406635 km ot centra Zemli (bliz Regula), a 17 avgusta nastupit maksimum deistviya meteornogo potoka kappa-Cignidy iz sozvezdiya Lebedya (ZHR= 3). 18 avgusta Luna (F= 0,04+) proidet severnee Merkuriya, a 19 avgusta pri faze 0,06+ - 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 46 gradusov, a dolgota dnya na toi zhe shirote - do 14 chasov 40 minut.

Luna v svoem dvizhenii po nebesnoi sfere posetit sozvezdiya Bliznecov, Raka, L'va i Devy, izmenyaya fazu ot 0,05- do 0,18+ i umen'shaya sklonenie, a takzhe vysotu verhnei kul'minacii. Nachalo nedeli nochnoe svetilo provedet v sozvezdii Bliznecov. Zdes' Luna probudet do 14 avgusta, kogda pri faze 0,04- pereidet v sozvezdie Raka. Zdes' v etot den' lunnyi serp (F= 0,02-) proidet severnee rasseyannogo zvezdnogo skopleniya Yasli (M44). 15 avgusta Luna (F= 0,01-) proidet severnee Venery, a zatem vstupit v sozvezdie L'va, gde 16 avgusta primet fazu novoluniya. V etot zhe den' molodoi mesyac (F= 0,01+) proidet severnee Regula, a 18 avgusta lunnyi serp (F= 0,04+) proidet severnee Merkuriya, a pri faze 0,06+ pereidet v sozvezdie Devy, gde proidet severnee Marsa 19 avgusta. Fazy Luny na dannoe vremya i na budushee.
