Has a direct motion of 21° 13′ 16″, and his diameter increases two tenths of one second. On the 14th, at 12:27 a. m., 12′ south of the moon. On the 1st, rises at 5:29 a. m., sets at 5:25 p. m.; on the 16th, rises at 4:56 a. m., sets at 5:24 p. m.; on the 30th, rises at 4:27 a. m., sets at 5:23 p. m.; on the 14th, at 12:27 a. m., twelve minutes south of moon.
JUPITER
May well be called this month the “Ruler of the Night.” From twilight till near the dawn his broad face looks condescendingly upon our little world, and by his example cheerily bids us “pursue the even tenor of our way.” Jupiter rises on the 1st at 2:26 p. m., sets next morning at 4:02 a. m.; on the 16th, rises at 1:24 p. m., sets on 17th at 3:02 a. m.; rises on 30th, at 12:29 p. m., and sets next morning at 2:07 a. m. Before the 21st, retrograde motion amounts to 36′ 26″; after that date to end of month, direct motion equals 8′ 42″; diameter diminishes three seconds, from 40.4″ to 37.4″. On 21st, at 3:00 p. m., stationary; on 23d, at 2:05 p. m., 4° 37′ north of the moon. It might be observed in passing that as a mean result of five years’ observations at the Dearborn Observatory, Chicago, the time of Jupiter’s rotation has been discovered to be greater by three seconds than was supposed in 1879.
SATURN
Sets at the following times: On the 1st, at 11:49 p. m.; on 16th, at 10:57 p. m.; on the 30th, at 10:09 p. m.; is, therefore, an evening star, and will remain so till the 18th of June. On the 18th, at 8:20 p. m., 4° 1′ north of the moon. Diameter diminishes from 16.6″ to 16″. Makes a forward (direct) motion of 3° 2′ 30″. For observation, this month is preferable to May. Can be found a little northwest of Zeta, in the constellation Taurus.
URANUS,
Unlike Saturn, retrogrades nearly one degree of arc during the present month, and shines from early eve to break of day, rising on the 1st at 5:18 p. m., and setting on the 2d at 5:22 a. m.; on the 16th, rising at 4:17 p. m., and setting next morning at 4:21; and on the 30th, rising at 3:19 p. m., and setting May 1st at 3:23 a. m., and can be seen all night by those who know where to find him (a little southwest of Eta, in the constellation Virgo). On 26th, at 12:16 a. m., 1° 17′ north of moon.
NEPTUNE,
Not only the father of waters, but water himself, scarcely visible at best, “hangs out” all day, rising soon after the sun, and setting as follows: On the 1st, at 9:36 p. m.; on the 16th, at 8:40 p. m.; on the 30th, at 7:46 p. m. Has a retrograde motion of 58′ 16″; and on the 16th, at 8:42 p. m., is 2° 13′ north of the moon.
