- <p> Visibility of Planets:

- <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: January 25 to March 19, May 24
- to July 4, and September 25 to October 20. The planet is brighter
- at the end of each period (the best conditions in northern
- latitudes occur from the beginning of October to mid-way through
- the second week of that month, and in southern latitudes during
- the last three weeks of February). It is visible in the evenings
- between the following approximate dates: January 1 to January 13,
- April 6 to May 5, July 19 to September 11, and November 19 to
- December 27. The planet is brighter at the beginning of each
- period (the best conditions in northern latitudes occur from mid-
- April to just a few days before the end of that month, and in
- southern latitudes from the early August to early September).

- <p> VENUS is a brilliant object in the evening sky from the
- beginning of the year until mid-way through the first week of
- June when it becomes too close to the Sun for observation. During
- the middle of June it reappears in the morning sky where it stays
- until the end of the year. Venus is in conjunction with Saturn on
- Feburary 3, with Mercury on June 23, and with Mars on June 30 and
- September 4.
- </p>
- <p> MARS is too close to the sun for observation until the
- middle of May when it appears in the morning sky. Its westward
- elongation gradulaay increases moving from Aries at the begining
- of May, into Taurus in early June (passing 6 degrees N of
- Aldebaran on June 27) and into Gemini in the last week of July
- (passing 6 degrees S of Pollux on August 31). It then continues
- through Cancer, Leo (passing 1.2 degrees N of Regulus on
- October 29) and into Virgo where after mid-December it can be
- seen for more than half the night. Mars is in conjunction with
- Mercury on May 31 and June 14, and with Venus on June 30 and
- September 4.
- </p>
- <p> JUPITER rises just before sunrise in Sagittarius in which
- it remains throughout the year. Its westward elongation gradually
- increases and from the second week of April it can be seen for
- more than half the night. It is at opposition on July 4 when it
- is visible throughout the night. Its eastward elongation then
- decreases and from the beginning of October until the end of the
- year it can only be seen in the evening sky.
- </p>
- <p> SATURN can be seen in the evening sky in Aquarius until the
- end of February when it becomes too close to the Sun for
- observation. It reappears in the morning sky during the first
- week of April in Pisces. Its westward elongation then gradually
- increases passing into Cetus in early June and Pisces again from
- early September 14 in which constellation it remians for the rest
- of the year. It is at opposition on September 26 when it 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 Venus on April
- 3.
- </p>
- <p> URANUS is too close to the Sun for observation until the
- mid-February when it appears in the morning sky in Capricornus,
- in which constellation it remains throughout the year. Its
- westward elongation gradually increases until on July 25 it is
- at opposition, when it is visible throughout the night. Its
- eastward elongation gradually decreases and from the mid-October
- until the end of the year it can only be seen in the evening sky.
- </p>
- <p> NEPTUNE is too close to the Sun for observation until the
- second week of February when it appears in the morning sky in
- Sagittarius, in which constellation it remains throughout the
- year. It is at opposition on July 18 when it can be seen
- throughout the night. Its eastward elongation gradually
- decreases and from mid-October until late December when it can
- be seen in the evening sky, after which it again becomes too
- close to the Sun for observation.
- </p>
- <p> DO NOT CONFUSE (1) Venus with Saturn from the end of January
- until the first week in February, with Mars from late
- June to early July and late August to mid-September and with
- Mercury in the fourth week of June; on all occasions Venus is the
- brighter object. (2) Mercury with Mars in the last week of May to
- the end of the thirs week of June; Mercury is the brighter
- object except for the last week in May. The reddish tint of Mars
- should assist in ots identification. (3) Jupiter with Mercury
- around mid-December when Jupiter is the brighter object.
