THE MOON
Presents the usual phases in order, as follows: First quarter on the 5th, at 4:27 p. m.; full moon on the 12th, at 10:19 a. m.; last quarter on the 20th, at 12:15 a. m.; and new moon on the 27th, at 11:53 p. m., Washington mean time, which is 8 minutes 12.09 seconds slower than “Eastern time,” or the time of the 75th meridian west of Greenwich. The moon is nearest the earth at 11:36 a. m. on the 9th; and most distant from the earth at 6:12 a. m. on the 21st. On the 10th she reaches her greatest elevation, which is 67° 42′ above the horizon in latitude 41° 30′ north.
MERCURY
Will be distinctly visible every evening from the first to the thirteenth of the month, setting at 6:06 p. m. on the evening of the former date, and at very nearly the same hour on the latter date. From the 1st to the 11th its motion is from west to east; on the 11th it is said to be stationary; however, it is actually moving in its orbit about thirty thousand miles per hour; but is approaching us in an almost direct line, and thus seems to be at a stand still. On the same day, it arrives at its greatest distance east of the sun, 19° 16′, and then starts on its journey west, approaching the earth, and coming directly between it and the sun, that is, reaching its inferior conjunction about 3:00 on the afternoon of the 20th. On the 31st it will be so far west as to rise one hour and fourteen minutes earlier than the sun.
VENUS
Will be evening star during the month, setting at 6:38 on the evening of the 1st, and at 7:50 p. m. on the 31st. Her motion is direct, amounting, during the month, to 2 hours, 24 minutes, 38 seconds, equal to 36° 9½′ of arc, her diameter increasing from 11.6′ to 12.8′. This planet will delight the vision of star-gazers, not only during January, but several succeeding months.
MARS
Will continue his retrograde motion during the month, moving a little more than one minute per day, making in all 35 minutes 37 seconds. He will be quite a prominent object during the entire night, on the evening of the 1st, rising at 7:50, and on the following morning setting at 9:58; and on the 31st rising at 5:08 p. m., and setting at 7:44 the next morning. His diameter at the latter date will be 15″. Can be readily found in the constellation Leo, northwest of the bright star Regulus. At 1:29 p. m. on the 14th he will be 9° 18′ north of the moon.
JUPITER
Will commence the month as a morning star, rising on the 1st at 6:19 in the evening, and setting next morning at 8:45; but on the 13th will change to an evening star, being on this date in opposition to the sun, and rising as the latter sets at about 5:00 p. m. On the 13th, at 2:53 a. m., he will be 5° 41′ north of the moon. On the 31st he will rise at 4:00 p. m., and next morning will set at 6:34. His diameter at same date will be 43.8″. Motion during the month, 16 minutes 12.54 seconds retrograde. The eclipses of this planet’s moons, by the body itself, are sometimes used for the purpose of determining longitude. He will be found in the constellation Cancer.
