V etot den' nochnoe svetilo vstupit v sozvezdie Skorpiona, gde pri faze 0,85+ pokroet Antares (vidimost' v Afrike).18 iyulya Luna (F= 0,88+) pereidet v sozvezdie Zmeenosca, a 19 iyulya pri faze 0,93+ vstupit v sozvezdie Strel'ca. 21 iyulya yarkii lunnyi disk pereidet v sozvezdie Kozeroga i primet fazu polnoluniya, nablyudayas' vsyu korotkuyu noch'. Fazy Luny na dannoe vremya i na budushee.
