Abstract
FULL moon occurs on June 14d. 18h. 42m., U.T., and new moon on June 29d. 04h. 06m. The following conjunctions with the moon take place: June 2d. 00h., Venus 0-2° S. ; June 2d. 18h., Saturn 3° S. ; June 4d. 19h., Mars 3° S. ; June 9d. 03h., Jupiter 4° S. ; June 30d. 10h., Saturn 3° S. ; June 30d. 23h., Mercury 3° S. In addition to these conjunctions with the moon, the following conjunctions occur: June 12d. 13h., Venus in conjunction with Saturn, Venus 1.7° N.; June 18d. 05h., Mars in conjunction with Regulus, Mars 0.8° N. ; June 24d. 01h., Mercury in conjunction with Saturn, Mercury 1.5° N. Occultations of stars brighter than magnitude 6 are as follows, the latitude of Greenwich being assumed: June 13d. OOh. 48.5m., p Scor. (D) ; June 13d. OOh. 49.6m., 56B. Scor. (D) ; June 13d. Olh. 24.9m., (3 Scor. (R). Mercury sets about 11/2 hours after the sun from the middle to the end of June and can be seen in the western sky after sunset. Venus is conspicuous in the western sky, setting at 22h. 28m. and 22h. 17m., at the beginning and end of the month respectively. The portion of the illuminated disk visible on the earth varies between 0.85 and 0-77 during June 1-30. Mars can be seen before midnight, setting at Oh. 19m., and 22h. 54m. at the beginning and end of the month respectively. The stellar magnitude of the planet varies from 1.5 and 1.7 between the above dates. Jupiter sets at 2h., and Oh. 06m. at the beginning and end of the month respectively and is stationary on June 15. The stellar magnitude of Jupiter is -1.8 throughout the month. Saturn sets nearly 3 hours after the sun on June 1, but after the middle of the month is too close to the sun for good observation. The fact that all five planets are visible at the same time towards the end of the month is worth noticing. An eclipse of the sun, invisible at Greenwich, occurs on June 29, and on June 14 a total eclipse of the moon, partly visible at Greenwich, takes place. The moon leaves the umbra at 20h. 33.6m. and the penumbra at 21h. 45.lm., and as moonrise at Greenwich occurs at 20h. 17m., very little of the eclipse is visible. Summer solstice is on June 2Id. Olh.
