POSITION OF PLANETS FOR OCTOBER, 1879
Mercury.
On October Mercury rises at oh,
Am. A. NJ, and sets at Oh. 3Sm. p.
NJ.
0naOctober 81 Mercury rises at Sh.
A. NJ, and sets at 5h. 2Im. PM.
Venus.
On October l Venus rises at 5h
14m. A. NJ, and sets at Al. BIN. p.
M.
On October 81 Venus rises at Oh.
lin. A. NJ, and sets at 3h. On; P.
NJ. -.
The motions Of Venus can be watch
ed by referring the planets places to
the stars in Leo, and it will be seen
that Venus moves toward the west I'M
til the 18th, and toward the east after
that date VEINS is near the waning
moon on the 18th, and at its greatest
brilliancy on the Both.
Mars.
Mars is coming into better position
for evening observers.
Mars rises on October ] at III. Sim
P. NJ, and sets at 10h. I'm. of the
next day. -e9
On October 81 Mars rises at 5h 39m.
P. ~, and sets at I'll sem. A. NJ. Of
the next day.
After October 6 the motion of Mars
among the stars will be toward the
west; it can be compared with the stars
of the Pleiades. Mas is in eoniunc-
ton with the moon on the 30th.
Jupiter.
Jupiter, Saturn, lnd Mars arc bril-
liant in the evening Of October.
Jupiter rises first. on October ! at
4h.25m. PM, on October 81 at Oh.
24m. 2. NJ.
An ordinary ships glass, or a good
opera glass, will show the varied posi-
tions of Jupiter and its four moons.
If we take the hours between Sand 10
in the evening for our observations we
shall see Jupiter rise, unaccompanied
Ivy its first satellite, on the 9th, in con-
sequence of the satellite coming in
front Of the planet and passing across
the disk. The same will occur on the
Dist and 2Sth.
She first satellite will go invisible
at some time during these hours on the
9th and Goth, because it is in the
shadow of the planet. On the Goth it
will not be seen, because behind the
planet.
The smallest satellite of Jupiter, the
second in order of distance from the
planet, well not be seen until near 10|
P. M. on the It'll. when it passes from
the face of the planet. 1t will disap-
pear about 0 P. NJ. on the 18th, be
cause it passes between the planet and
the earth and is thus projected upon
the face of Jupiter.
The third satellite of Jupiter, which
is the largest, will disappear by going
behind the planet, October9 The APP
proach of the satellite and planet can
be watched, and It's motion around
Jupiter can be followed; it will reap
pear after midnight. This satellite
will pass across the disk of Jupiter be-
tween 6 and 10 P. NJ. of the 9th; it
will be seen to pass from the face OF
Jupiter between 8 and 10 p. NJ.
The fourth satellite Of Jupiter will
reappear from the shadow Of Jupiter
on the 25th. between s and 8 P. NJ.
Saturn.
Saturn comes to its best position ear
~ in October. A small telescope will
show the ring projecting on each side
the planet.
Saturn rises on October l at Oh. P.
NJ, and on October 81 at 3h. sem. P.
NJ.
Saturn is in conjunction with the
moon on 9th at midnight, Saturn be
ing abont s south of the moon.
Uranus.
On October l Uranus rises at 3h.
20m. Il. NJ. On October 81 Uranus
rises at In. 29m. A. Nj.
Uranus is very near the star Rho
Leonis.
Neptune.
Neptune rises on October l at III.
I'm. p. NJ, and on October 81 at 5h.
I'm. p. NJ.
Between 4 and s P. NJ. of October
/, Jupiter, Saturn, Neptune, and Mars
come above the horizon; and on the
3lst the same planets rise between 9
and 6 p. M.-Scientific American.
