FULL moon occurs on July 6d. 04h. 27m. U.T., and new moon on July 20d. 05h. 42m. The following conjunctions with the moon take place: July 18d. 08h., Saturn 1° N.; July 22d. 0lh., Mercury 0·7° S.; July 22d. 20h., Jupiter 2° S.; July 23d. llh., Mars 2° S. The following conjunctions in addition to the above also take place: July 5d. 08h., Mars in conjunction with Jupiter, Mars 0·2° N.; July 10d. 04h., Mars in conjunction with Regulus, Mars 0·7° N.; July 20d. 12h., Jupiter in conjunction with Regulus, Jupiter 0·5° N.; July 28d. 08h., Mercury in conjunction with Regulus, Mercury 0·01° N.; July 29d. 17h., Mercury in conjunction with Jupiter, Mercury 0·7° S. Occupations of stars brighter than magnitude 6 are as follows: July 2d. 21h. 20·9m., θ Libr (D); July 30d. 21h. 57·7m., χ Ophi. (D). The times refer to the latitude of Greenwich and (D) means disappearance. Mercury is in inferior conjunction on July 1. At the middle of the month the planet sets 50m. after the sun and at almost the same interval at the end of July. Venus is too close to the sun to be conveniently observed until late in the month. On July 31 the planet sets less than half an hour after the sun. Mars, in the constellation of Leo, can still be observed as it sets 2h. after the sun at the beginning of July and 1h. 10m. after sunset on July 31. Jupiter, in the constellation of Leo, is drawing near the sun, setting only 50m. after sunset at the end of July. Saturn is no longer visible. The earth reaches aphelion on July 3 when its distance from the sun is 94,560,000 miles. An annular eclipse of the sun, invisible at Greenwich, takes place on July 20. At Bombay the magnitude of the eclipse is 0·95, at Hong Kong 0·90, and at Madras 0·80.
