- <p> Visibility of Planets:
- </p>
- <p> MERCURY can only be seen low in the east before
- sunrise, or low in the west after sunset (about
- the time of the beginning or end of civil
- twilight). It is visible in the mornings between
- the following approximate dates: February 10 to
- April 6, June 15 to July 20, and October 12 to
- November 8. The planet is brighter at the end of
- each period (the best conditions in northern
- latitudes occur from mid-October to just a few days
- before the end of that month, and in southern latitudes
- from the third week of February until the third week
- of March). It is visible in the evenings between the
- following approximate dates: January 1 to January 29,
- April 22 to May 26, August 6 to September 29, and
- December 10 to December 31. The planet is brighter at
- the beginning of each period (the best conditions in
- northern latitudes occur during the first half of May
- and in southern latitudes from the third week of August
- until the third week of September).

- <p> VENUS is too a brilliant object in the morning sky
- from the beginning of the year until mid-July when it
- becomes too close to the Sun for observation. During the
- last week in September it reappears in the evening sky
- where it stays until th eend of the year. Venus is in
- conjunction with Jupiter on January 14 and November 19,
- with Saturn on April 19, with June 19 and September 28,
- and with Mars on November 22.
- </p>
- <p> MARS rises well before midnight at the beginning
- of the year in Leo (passing 4 degrees N of Regulus on
- January 28) and is at opposition on February 12, when
- it is visible throughout the night as a bright, reddish
- object. Its eastward elongation gradually decreases and
- from late May it is visible only in the evening until
- late December when it becomes too close to the Sun for
- observation. It passes from Leo to Cencer, back into
- Leo, then moves through Virgo, Libra, Scorpius,
- Ophiuchus, and into Sagittarius at the end of November.
- Mars is in conjunction with Jupiter on November 16,
- with Venus on November 22, and with Mercury on December
- 23.
- </p>
- <p> JUPITER rises well before sunrise at the beginning
- of the year in Scorpius, moving into Ophiuschus by mid-
- January, and by early March can be seen for more than
- half the night. Its westward elongation gradually
- increases until on June 1 it is at opposition when it
- is visible throughout the night. Its eastward
- elongation then decreases as it passes from Ophiuschus
- into Scorpius by early July and returning to Ophiuschus
- in late August where it remains until early December
- when it becomes too close to the Sun for observation.
- Jupiter is in conjunction with Venus on January 14 and
- November 19, and with Mars on November 16.
- </p>
- <p> SATURN can be seen in the evening sky from the
- beginning of the year in Aquarius until mid-February
- when it becomes too close to the Sun for observation.
- It reappears in the morning sky during the second half
- of March still in Aquarius, in which constellation it
- remains throught the year. Its westward elongation
- gradually increases until September 14 when it is at
- opposition and is visible throughout the night.
- Its eastward elongation then gradually decreases
- until mid-December when it can only be seen in the
- evening sky. Saturn is in conjunction with Mercury
- on March 26 and with Venus on April 13.
- </p>
- <p> URANUS is too close to the Sun for observation
- until the second week in February when it appears in
- the morning sky in Sagittarius, in which constellation
- it remains throughout the year. Its westward elongation
- gradually increases passing into Capricornus in early
- March, returning to Sagittarius during the first half
- of July, until on July 21 it is at opposition, when it
- is visible throughout the night. Its eastward
- elongation gradually decreases and from the second half
- of October it can only be seen in the evening sky,
- passing back into Capricornus in late December.
- </p>
- <p> NEPTUNE is too close to the Sun for observation
- until the early February when it appears in the morning
- sky in Sagittarius, in which constellation it remains
- throughout the year. It is at opposition on July 17
- when it can be seen throughout the night, after which
- its eastward elongation gradually decreases and from
- mid-October it can only be seen in the evening sky
- until late December when it again becomes too close to
- the Sun for observation.

- <p> DO NOT CONFUSE (1) Venus with Jupiter in mid-
- January and mid-Novermber and with Mercury in mid-July;
- Venus is always the brighter object. (2) Venus with
- Saturn with in mid-April and with Mars in the second
- half of November and early December; Venus is always
- the brighter object. (3) Mercury with Saturn in late
- late March and with Mars in the second half of
- December; Mercury is always the brighter object. (4)
- Jupiter with Mars in mid-November when Jupiter is the
