8 PLANET

NOTES, 1992

VISIBILITY OF PLANETS

VENUS is

a

brilliant object in the morning sky from

the beginning of the year until the second week in May

when it becomes too close to the Sun for observation.

During the

second

half of July it reappears in the

evening sky

where it

stays

until the end

of

the

yea

r.

Venus

is in conjunction with Mars on February I9,

with Saturn on February 29 and December 2I, with

Mercury

on April 5

and July

25 and

with Jupiter on

August 23.

MARS can be

seen

at the

very

beginning

of January

in

the morning

sky

in

Ophiuchus

then it passes through

Sagittarius,

Capricornus,

Aquarius, Pisces, briefly into

Cetus and back into Pisces,

on to

Aries and Taurus

(passing 5

°N

of

Aldebaran

on August II), Gemini

(passing 5

°

S of

Pollux on November 4 by which time it

can be seen

for

more

than half the night), Cancer and

back

into

Gemini

in mid

December

where it remains

for

the rest

of

the

year (passing

3°S

of

Pollux on

December 22).

Mars

is in conjunction with Mercury

on

January

IO,

with Venus

on

February

I9

and

with Saturn

on

March 6.

JUPITER

can be seen

in January

for more than half

of

the night in Leo, its westward

elongat

ion

gradually

increases

until it

is at oppos

ition on February

29 when

it

can

be

seen

throughout the night. Its eastward

elonga-tion then

gradually decreases until by early June it can

be seen only

in the evening

sky. In

early September it

becomes too

close

to the Sun

for observation

until

the

beginning of

October when

it reappears in the morning

sky in Virgo in which

constellation it

remains for the

rest of the

year

.

Jupiter is in conjunction with Venus

on

August 23.

SA

TURN can be

seen

in the evening

sky in Capricornus

until mid-January then "it becomes too

close to

the

Sun

for observation

.

It

reappears in the morning

sky in

mid-February still

in

Capricornus in

which constellation it

remains throughout the

year. I

ts

westward elongation

gradually increases until

it is at opposition on

August

7 when

it is

visible

throughout the night. Its eastward

elongation

then gradually decreases until from

early

November

it can

only

be

seen

in the

evening sky.

Saturn is in conjunction

with Venus on

February 29

and

December

2I

and with Mars on March 6.

MERCURY can only

be

seen

low in the

east

before

sunrise, or

low in the

west after sunset (ab0:ut

the time

of

the beginning

or end of civil

twilight). It

PLANET DIAGRAM

General Description. The diagram on the opposite page

s

how

s,

in graphical form for any date during the year,

the local mean time of

meridian passage of

the Sun,

of

the five planets Mercury, Venus, Mars, Jupiter and

Saturn, and of each 30° of S

.

H.A.; intermediat

e

lines,

corresponding to particular stars, may be drawn in by

the user if he

so

desires. It is intended to

provide

a

general pi_cture of the availability of planets and

stars

for

obse

r

va

tion.

On

each side

of the line marking the time of meridian

passage

of

the Sun a band,

45 m wide, is

shaded

to

indicate that planets

and

most stars crossing the

meri-dian within 45m of the

Sun

are too close to the Sun for

observat

ion.

Method

of use and

interpretation.

For any date-

the

diagram

provides immediately the iocal mean times

of

meridian passage

of

the

Sun,

planets. and

stars,

and

thus the

following

information:

(a)

whether a

planet

or star

is too close to the Sun

for observation;

(b)

some indication of

its pos

iti

on

in the

sky,

es-pecially

during twilight;

(c)

the proximity of

other

planets.

Whe

n the meridian passage

of

an outer planet 9ccurs

at

midnight the body is in

opposi

ti

on

to the Sun

and is

v

i

sible

all night;

a

planet may

then

be observable during

both

morning

and

evening

twilig

ht

s.

As the time

of

rrie-ridian passage decreases, the body

eventua

lly ceases

to

be observable in th"e morning, but its altitude above

the

eastern

horizon

at sunset

gradually increases; this

continues

until the body is on the meridian during

evening twilight. From then

onwards

the body is

ob-servab

le above the

wes

te

rn

horizon

and

its altitude at

sunset gradua

lly

decreases;

event

uall

y

the body

becomes

too close to the

Sun for observa

t

ion.

When

the body again

becomes

visible

it i

s

seen low

in the

east

during

morning twilight; its

altitude

at

sunrise

increases

until

meridian passage occurs during morning twilight.

Then,

as the time

of

meridian passage decreases to

o",

the body

is

observable

in the

west

during morning

twilight

with

a

gradually decreasing altitude, until

it

once

again reaches opposition.

DO NOT

CONFUSE

Mercury with

Mars during

the first half of January,

the

reddish

tint

of Mars should ass

a-tion.
