Abstract
New moon occurs on Oct. 14d. 06h. 10m., u.t., and full moon on Oct. 29d. 20h. 07m. The following conjunctions with the moon take place: Oct. 8d. 21h., Mars 4° S.; Oct. 9d. 22h., Saturn 5° S.; Oct. 16d. 04h., Mercury 4° S.; Oct. 17d. 05h., Jupiter 1° N. In addition to these conjunctions with the moon, Mercury is in conjunction with Venus on Oct. 29d. 09h., Mercury being 2·7° S. Mercury and Venus are evening stars but set too soon after the sun for favourable observation. Mars, in the constellation of Cancer, can be seen during the morning hours, rising at 23h. 37m., 23h. 25m., and 23h. 09m., at the beginning, middle, and end of the month, respectively. Jupiter, in the constellation of Scorpius, is visible only during the early portion of the night, setting at 19h. 17m., 18h. 29m., and 17h. 35m., at the beginning, middle, and end of the month, respectively, in the last case just an hour after sunset, and at this time it is very close to β Scorpii. Saturn, in the constellation of Leo, cannot be seen until the early morning hours, rising at 1h. 26m., 0h. 38m., and 23h. 42m., at the beginning, middle, and end of the month, respectively, and can be easily identified by its position with reference to Regulus, of which it is a little west. An occultation of only one star brighter than magnitude 6 takes place: October 4d. 3h. 17·8m., 13 Tauri (R), the latitude of Greenwich being assumed and R referring to reappearance. The Orionid meteors are active from about October 18–26, but towards the end of this period moonlight will partly interfere with the observations. On October 26 the moon sets at 2h. 14m.
