Abstract
FULL moon occurs on Oct. 7d. 02h. 52m., U.T. and new moon on Oct. 21d 21h. 23m. The following conjunctions with the moon take place : Oct 17d. 13h. Mars 3 S. ; Oct. 19d. 00h., Saturn 1 S. ; Oct. 20d. 16d. mercury 1°N.; oct. 25d.04h., vennus 2°N.; oct. 20d. 21h., Jupiter 5° N. Mercury is in inferior conjenction on Oct. 3, stationary on Oct. 12, and at its greatest elongation west on Oct. 19. The planet becomes a morning star, rising Ih. 40m. and Ih. 25m. before the sun on Oct. 15 and 31, respectively. Venus sets about an hour after the sun on Oct. 1 and If hours after the sun on Oct. 31, and can be seen in. the western sky in the evening, stellar magnitude—3.7, the visible portion of the illuminated disk varying from about Q-7 to 0-6. Mars, in the constellation of Cancer, rises at Ih., Oh. 50m. and Oh. 40m. at the beginning, middle and end of the month, respectively, and can be seen in the morning hours, stellar magnitude 1-6. Jupiter, in the constellation of Sagittarius, sets about 23h., 22h. and 21h. 10m. at the beginning, middle and end of the month, respectively, and is visible fairly low in the sky in the earlier part of the night. Saturn is visible as a morning star, its times of rising being 3h. 40m. on Oct. 1 and 2h. on Oct. 31. Occultations of stars brighter than magnitude 6 are as follows: Oct. 14d. OOh. 43-3m., 49 Auri. (R) ; Oct. 29d. 19h. 51-Cm., 37 Capr. (D) ; Oct. 29d. 21h. 33-2m., e Capr. (D). R and J9 refer to reappearance and disappearance, respectively, and the latitude of Greenwich is assumed. The Orionid meteors are active about Oct. 18 for a few nights, and moonlight will not interfere with the observation of this shower. There will be a total eclipse of the moon on Oct. 6-7, visible at Greenwich, the circumstances of which are as follows :
