Abstract
FULL moon occurs on July 14d. 09h. 22m. U.T. and new moon on July 28d. 11h. 53m. The following conjunctions with the moon take place: July 1d. 19h., Venus 3° S. ; July 3d. 07h., Mars 4° S. ; July 6d. 11h., Jupiter 4° S. ; July 31d. 15h., Venus 5° S. ; July 31d. 23h., Mars 5° S. Occultations of stars brighter than magnitude 6 are as follows, in the latitude of Greenwich: July 7d. 20h. 37.3s., x Virg. (D); July l1d. 21h. 19.5m., b Ophi. (D); July 18d. 0lh. 17.lm., 69 Aquar. (R). Mercury can be seen in the western sky in the early portion of the month, but later on it is too close to the sun for favourable observation. The planet attains its greatest western elongation on July 5 and is stationary on July 19. Venus sets at 22h. 16m. and 21h. 15m. at the beginning and end of the month respectively, and is conspicuous in the western sky. The stellar magnitude of the planet is -3.5 in the earlier portion, and -3.6 in the later portion, of the month. Mars sets 2½ hours after the sun on July 1, but at the end of the month only 1½ hours after the sun and is not well placed for observation in the latter case. Jupiter, near 0 Virgin is, sets at midnight on July 1 and about 1½ hours after the sun on July 31. The stellar magnitude of the planet varies from - 1.7 to - 1.5 during this period. Saturn is drawing in too close to the sun for favourable observation. The earth reaches aphelion on July 3d.
