On the 1st the Moon will be at Perigee – its closest approach to Earth in 2000 at a distance of 337,362km. On the 4th the Earth is at aphelion – the furthest distance from the Sun in its orbit – at a distance of 1.016742 Astronomical Units (1AU = 149.6km).


THE PLANETS THIS MONTH.


MERCURY.

Mercury is at inferior conjunction on the 6th but starts a morning apparition on the 24th, the details of which can be found from this TABLE.


VENUS.

Venus is starting to recover from last month’s encounter with the Sun but it will not be for a few months when it will travel far enough away from the Sun to be easily visible.


MARS.

Mars is in conjunction with the Sun on the 1st.

MARSWATCH – latest observations of the red planet.


ASTEROIDS.

  • Vesta at opposition on 16th between Capricornus and Sagittarius and lies to the right of the Uranus and Neptune, (see below), close to M75 on July 1st. At just naked eye it can be seen under good clear skies.

For More information on Asteroids Click Here.


JUPITER.

Jupiter’s apparent diameter increases as it moves away from May’s Solar conjunction. At the start of the month the planet will appear 34.3 seconds of arc across whilst at the end of the month, when Jupiter is a little better placed in the morning sky (in the constellation of Taurus), it will be 36.7″ across. On the 26th (at 21h) Jupiter is 4.5° North of the crescent Moon.

Launched in October 1989, the Galileo Jupiter Probe entered orbit around the great planet on December 7th 1995. The Project Galileo Homepage will give you up-to-date information and the very latest images returned.


SATURN.

Saturn, like Jupiter is still recovering from solar conjunction in May and it will not be until the end of the month when these two planets will be favourably placed for anyone getting up to observe in the early hours of the morning. On the 26th (at 11h) Saturn is 3° North of the Moon.


URANUS and NEPTUNE.

Uranus at Mag 5.7, having overtaken slower moving Neptune some years ago now, heads slowly through the constellation of Capricornus

Neptune, like Uranus, lies in the constellation of Capricornus and is at opposition this month on the 27th at mag 7.9

JUPITER.

Jupiter is now a morning object in the constellation of Taurus but will rise only one hour before the Sun does. From the 24th follow the Moon as it becomes a thin crescent and heads towards the Sun On the morning of 29th, Jupiter will be 5° above the Moon.

Launched in October 1989, the Galileo Jupiter Probe entered orbit around the great planet on December 7th 1995. The Project Galileo Homepage will give you up-to-date information and the very latest images returned.


SATURN.

Saturn can be close to Jupiter in the morning sky, with Jupiter the brightest of the two. Look at the close groupings of Moon, Jupiter and Saturn around the 28th of the month.


URANUS and NEPTUNE.

Both planets rise before midnight by the end of the month so those patient enough to wait up until the early hours will be amongst the first to get a glimpse of these two planets. Even if you cannot see them directly a few long exposure photographs of the region using a 135mm lens will reveal them when the photo is compared with a good star atlas which shows faint stars.

THE PLANETS THIS MONTH.

SOLAR SYSTEM GET-TOGETHER

Although it’s not as rare an event as popularly rumoured, there really is an uncommon grouping, NOT alignment, of the Sun, Moon, and five naked-eye planets in early May. On the 5th they will all be gathered along a span of the ecliptic 27° long. On May 17th the Sun and planets, (with the Moon having moved away), will fit within a span of just 20° of sky. Venus and Jupiter have their closest conjunction, (42′ acrsecs,) since 1892 on May 17th. This will make a grand sight… well sadly not, because the Sun is smack in the middle of this span, hiding even the bright planets in its glare. Only Mercury and Mars will be visible low in the North-Western sky after sunset by mid-month. However the grouping of planets in September 2040 will be better observed, with all the planets East of the setting Sun, see below.

Diagrams of Planetary Groupings for February 5th, 1962, May 5th, 2000 and September 9th, 2040


MERCURY.

Mercury is at superior conjunction with the Sun on the 9th as seen from the Earth but quickly begins its second favourable evening apparition this year on the 20th. It will very quickly become prominent, although low down, in the North West, lying as it does in the constellation of Taurus and moving into Gemini by month’s end. This table describes the apparition as it progresses. There is no conjunction between Mercury and the Moon this Moon.


VENUS.

Venus will remain an unfavourable object between now and early September when it will become visible in the evening sky.


MARS.

Mars sets just after 22h by the end of the month and is now too close to the Sun to be easily visible.

MARSWATCH – latest observations of the red planet.


ASTEROIDS.

  • Hygeia is at opposition on May 25th at mag 9.2 in Scorpius
  • Ceres can be found in Virgo at mag 7.6
  • Vesta is in Sagittarius at mag 7.0.

For More information on Asteroids Click Here.


JUPITER.

Jupiter is at solar conjunction on the 8th is also unfavourable. It will swap positions with Saturn on the 28th with Jupiter passing slowly 1° North of Saturn very low down to the right of the rising Sun. Such conjunctions between these two planets occur roughly once every 19 years.

Launched in October 1989, the Galileo Jupiter Probe entered orbit around the great planet on December 7th 1995. The Project Galileo Homepage will give you up-to-date information and the very latest images returned.


SATURN.

Saturn is at solar conjunction just two days after Jupiter on the 10th, thus unfavourable for observations until End of June.


URANUS and NEPTUNE.

Uranus is starting to become favourable among the stars of Capricornus. It shines at Mag 5.8.

 Positions for the 1st May:

                          R.A.                   DEC                    TRANSIT TIME           MAG

Bluish Neptune is also in Capricornus at this time less brighter than Uranus. Both should be seen in dark sky location with clear skies.

Positions for the 1st May:

                          R.A.                   DEC                    TRANSIT TIME           MAG

THE PLANETS THIS MONTH.


MERCURY.

Mercury is not favourable to view this month.


VENUS.

Venus may still be visible very shortly before Sunrise but it must be regarded as unfavourable now as it continues its journey away from us toward the back of the Sun.


MARS.

Mars, drawn by Ken Clarke, as viewed through a 10" F4.3 Reflector 308x,432x. w=14.4, seeing 3-5, at 00:00 UTC on November 4th, 1990

w=14.4, seeing 3-5, at 00:00 UTC on November 4th, 1990

Mars is also poorly placed, lying 25° away from the Sun at the start of the month. Look towards the West on the 6th and Mars will pass 1° North of slower moving Jupiter as they both head towards the Sun. On the same day the Moon lies 6° South.Nine days later, on the 15th Mars passes 2° North of Saturn. This maybe a good time to record a series of observations – either photographic or a drawing – each day from the start of the month and track the planets as they all head towards an inevitable rendezvous with the Sun.

MARSWATCH – latest observations of the red planet.


ASTEROIDS.

  • 20 Massalia is at oppostion at Mag 9.6 in Virgo on April 14th.
  • 1 Ceres is well placed, also in Virgo at mag 7.0 on April 1st.

For More information on Asteroids Click Here.


JUPITER.

Jupiter is part of the “Dance of the Planets” with Saturn and Mars low in the West after Sunset.

Launched in October 1989, the Galileo Jupiter Probe entered orbit around the great planet on December 7th 1995. The Project Galileo Homepage will give you up-to-date information and the very latest images returned.


SATURN.

Saturn is also closely involved with Jupiter and mars in the evening sky in the West at 21h:00 mid month.


URANUS and NEPTUNE.

Uranus is slowly recovering from its February solar conjunction, and can be seen at Mag 5.9 in Capricornus.

PLUTO.

Pluto can be found on the border of Ophiuchus and Scorpius, roughly between the 4th magnitude stars zeta and 20 Ophiuchi. The best time to look for the planet is around New Moon. The dates below will be a guide for planning observations.

 

Positions for April are when pluto's elongation angle is greater than 90°.

March 20th marks the date of the Spring Equinox when the Sun crosses the celestial equator in Pisces heading North. March is also the month when the clocks are traditionally advanced by one hour in Britain to take us into British Summer Time (BST). As far as this page is concerned, you will have to added one hour to any times stated to obtain BST.


THE PLANETS THIS MONTH.


MERCURY.

Mercury is at Inferior Conjunction on the 1st and is therefore unobservable.


VENUS.

Venus is close too the Sun for observation and will not become favourable again until September 2000 when it reappears in the evening sky.


MARS.

Mars is heading towards Jupiter and Saturn in the evening sky and sets at 21h:05m at the end of the month.

MARSWATCH – latest observations of the red planet.


ASTEROIDS.

On March 22nd the minor planet Ceres will be at opposition in the constellation of Virgo. Usually asteroids are quite faint but once in a while one of the larger minor planets brightens enough to become visible using binoculars. Virgo is quite a large constellation and contains the bright star Spica. Part of the constellation looks like a upturned bowl and its the star gamma Virginis were the bowl appears to pivot. Long exposure photography (5 mins plus) of the area undertaken every few days will record Ceres’ motion against the background stars.

  • 7 Iris at mag 8.1 is close to M67 in Cancer during March and April.
  • 2 Pallasat mag 7.4 is in Monoceros during March, but is just above the Head of Hydra by early May.

Click HERE for Bright Minor Planets Ephemeridesfor 2000.


JUPITER.

Jupiter lies only 52° away from the Sun now and is moving closer to it all the time. Soon it will be lost in the glare of the evening twilight and there are very few celestial bodies which appear close by to break the monotony of the faint constellation of Cetus, North of which it passes this month. On the 9th at 20hrs Jupiter lies 5° North of the Crescent Moon.

Launched in October 1989, the Galileo Jupiter Probe entered orbit around the great planet on December 7th 1995. The Project Galileo Homepage will give you up-to-date information and the very latest images returned.


SATURN.

Saturn is only marginally better than Jupiter and soon it too will be lost in the Solar glare but still sets over three hours later than the Sun. On the 10th (at 11h) the Moon passes 4° South.


URANUS and NEPTUNE.

Both outer planets are unfavorable for observations at this time.


PLUTO.

Pluto can be found in Ophiuchus, between 4.6 magnitude stars 20 Ophiuchi and Zeta Ophiuchi. The best time to look for the planet is when the Moon is not around. With this in mind the dates given below, calculated as either side of the New Moon, maybe used as a guide for planning an observing session.

Best seen between March 1st and March 13th.

The Positions have been calculated for every ten days at 00h U.T. throughout the period of March 2000 when Pluto's elongation angle is greater than 90°.
 Positions are for Epoch 2000.

THE PLANETS THIS MONTH.


MERCURY.

Planets visible in the early evening sky, February 2000

Planets visible in the early evening sky, February 2000

As was mentioned last month Mercury sees an evening apparition stretching to 18° away from the Sun on the 15th. This Table show where to look using the Moon as a guide early on in the apparition.


VENUS.

Venus is a poor morning object now, clinging to the South Eastern horizon just before the Sun rises.


MARS.

Mars sets before 21:00hrs throughout February. A mere 4.4 arcseconds arcseconds across in the middle of the month the red planet is a poor telescopic object and its only close apparent approach to another celestial body is on the 8th when the Moon passes 4° South at 19:00hr.

MARSWATCH – latest observations of the red planet.


ASTEROIDS.

  • Vesta is 0.4° North of Moon on Feb 1st.
  • Ceres is stationary on Feb 10th, and Pallas on Feb 26th.

For More information on Asteroids Click Here.


JUPITER.

Jupiter is a little more favourable than Mars, showing a disk well over 35 arcseconds across and transiting just after 17:oohrs at the start of the month and setting at 22:45hrs at the end. On the 11th (at 05:00hrs) Jupiter lies 5° North of the Moon.

Launched in October 1989, the Galileo Jupiter Probe entered orbit around the great planet on December 7th 1995. The Project Galileo Homepage will give you up-to-date information and the very latest images returned.


SATURN.

Saturn, at only 18 arcseconds across, shows less disk detail than its more illustrious neighbour but its ring system, tilted at 19° to the ecliptic, more than makes up for any blandness. Saturn isn’t always quiescent; look carefully at the disk using a high magnification. If the seeing is good i.e. when the air is still enough then at least one pastel-shaded band may be seen and occasionally a `white storm’ blows up which is quite evident.


URANUS and NEPTUNE.

Uranus is at Solar conjunction on the 6th, whilst Neptune is only just starting to recover from its Solar conjunction late last month. It will be May when both planets begin to improve sky locations.


PLUTO.

Pluto will be out of view until after April in morning skies.



METEORS.

  • February 6th – 9th Alpha Aurigids ZHR is 12 per hour. ( Favourable) New Moon on 5th, radiant high up.

COMETS.

  • February 5th Comet Showmaker-Levy 2 at Perihelion (1.869AU).
  • February 27th Comet C/1993 K3 (Linear) at Perihelion (1.929AU).
  • Comet C/1994 S4 (Linear) is slowly brightening.Could be a naked eye object in July.
