Presents himself as an object of interest for a few mornings before
and after the 5th, the day on which he reaches his greatest western
elongation, 17° 58′ from the sun; and as he rises nearly an hour and a
half earlier than the latter body, may with a little care be clearly
distinguished. His times of rising are as follows: On the 1st at 4:33;
16th, at 5:12; and 31st, at 6:22 a. m. His motion is direct and amounts
to 43° 46′. As he moves away from the sun, after 6:00 a. m. on the 3d,
his diameter diminishes from 7.4″ to 4.6″. On the 17th, at 7:58 p. m.,
he is 2° 1′ north of the moon.
VENUS
Remains a morning star during this month, shining, toward its close, with
somewhat decreased brilliancy. Her motion is altogether eastwardly, and
amounts to 33° 12′ 46″, diameter changing from 21.6″ on the 1st to 17.6″
on the 31st. On the 1st, she will rise at 2:13; on the 16th, at 2:35; and
on the 31st, at 3:01 a. m. On the morning of the 7th the trio, Jupiter,
Venus and _Alpha Leonis_ (Regulus) will give an exhibition worth much
more than all the trouble it costs to obtain the view. Jupiter rises
first at 2:30; a few minutes later, and to the south, Venus appears, and
almost at the same time a little northward, Regulus: the three presenting
a combination rarely witnessed. On the 6th, at 11:00 a. m., Venus will be
1° 15′ south of Jupiter; on the 7th, at 7:00 p. m., 55′ south of Regulus;
and on the 15th, at 2:48 a. m., 3° 35′ north of the moon.
MARS,
Though accounted an evening star, will be above the horizon in the day
time most of the month, on the 1st rising at 8:55 a. m. and setting at
7:01 p. m.; on the 16th, rising at 8:50 a. m. and setting at 6:32 p. m.;
and on the 31st, rising at 8:46 a. m., and setting at 6:08 p. m. Its
declination on the 31st is 21° 34′ south. Motion for month direct and
amounting to 22° 28′. Diameter decreases from 4.6″ to 4.4″. On the 21st,
at 6:15 a. m., 4° 10′ south of the moon.
JUPITER
(Together with Venus) makes this month’s mornings brilliant. Rising on
the 1st at 2:26, on the 16th at 1:44, and on the 31st at 12:57 a. m.; and
his diameter increasing from 31″ to 32.2″, makes each stay appear longer
and each return brighter. His motion is direct and equals 4° 56′ 51″. On
the 6th, at 11:00 a. m. he is 1° 15′ north of Venus; and on the 14th, at
11:57 a. m., 4° 42′ north of the moon.
SATURN
Rises on the 1st at 9:29 p. m., and sets on the 2nd at 12:09 p. m.; rises
on the 16th at 8:29 p. m., and sets on the 17th at 11:09 a. m.; rises on
the 31st at 7:29 p. m., sets 10:02 a. m. on November 1st. His motion, 42′
26″, is retrograde. Diameter increases from 17.8″ to 18.8″. On the 5th,
at 8:00 a. m. is stationary; and on the 9th, at 3:50 p. m., 3° 30′ north
of the moon.
