Total Lunar Eclipse This Month

In the early morning hours of September 27th there will be a total Eclipse of the Moon, when the Moon enters the shadow cast into space by the Earth. The Moon will lie in the constellation ofPisces and first contact with Umbral is at 02:12BST as seen from Liverpool. Totality starts at 03:19mBST, when the Moon appears a Copper red colour,( the darkness of which will indicate how polluted the earth’s atmosphere is).Totality will end at 04:29BST and the Moon will appear whole again at 05:36mBST.

THE PLANETS.

MERCURY

After reaching inferior Conjunction on the 17th Mercury starts off an excellent morning apparition at the end of the month, lying almost 9 degs above the horizon at the start of Civil Twilight on the 30th.

VENUS

Lies almost directly above Mercury but 20 degs further up from the horizon. Venus is slowly fading in brightness although the difference will be impossible to detect through casual observation. More discernable are the changes in the planets phase and apparent diameter. From a cresent phase of 49′ of arc across in June, when the planet was starting its Morning apparition, it is now only 18″ arc arcoss and is showing a gibbous phase. On the 4th Venus is 3 degs South of Mars.

MARS

Together with Venus Mars is heading for a close conjuction with the “Beehive” M44 star cluster in Cancer the crab. Binoculars offer the best wide-field view but a telescope will show Mars and M44 in the same field on the 21st. Venus will pass just 2.5 degs South on the 14th. Mars will be a mere 30″ arc secs from M44 on the 21st. The Moon will join in on the nights of 7th, 8th and 9th.

JUPITER

Crosses the meriden at 21:00h on the 1st, (20h:10m on 30th) and its large apparent diameter of 40″ arc secs makes it a far more satisfying sight than either Venus at 18 arc secs or Mars only 4.5″ arc secs. Having resumed normal West-East motion, Jupiter passes by M22 again, this time on the 21st with the lst quarter Moon lying 5.5 degs to the North.

Jupiter was the centre of attention on December 7th 1995 after the NASA Galileo Spacecraft entered orbit around Jupiter. The orbiter will encounter Jupiter’s Moon Ganymeade on the 6th. The Galileo Homepage should keep you up-to-date with news and images returned.

SATURN

Is at opposition on the 26th, its disk is half the diameter of Jupiter’s and its markings are nowhere near as pronouned. Steady seing conditions and very patient observing will enable the observer to see the subtle banding and transient markings such as white spots. If favourable placed Titan – Saturn’s largest Moon, may be viewed even with smallish telescopes. Large amateur telescopes will show more of Saturn’s system of moons. On the 27th Saturn is 3 degs South of the Moon.

URANUS and NEPTUNE.

Both are now disappering into evening twilight, but can be found low in South West sky between Capricornus and Sagittarius. Neptune will be celebrating its 150 year since its discovery this month.

PLUTO

Is Badly placed for observations at the moment.

THE PLANETS

MERCURY

Is at Superior Conjunction in the 28th.

VENUS

Is now a spectacular sight high up in the South-Western sky shortly after Sunset, unmistakeable even in bright twilight. On the 23rd it can be seen 5.5degs North of the Moon,and over the next few weeks will being to track towards a close conjunction with the Pleiades star cluster in Taurus. So any of you with a suitable camera and telephoto lens this grouping should not be missed. Venus reaches Perihelion in its orbit on March 22nd, and greatest elongation from the Sun on March 31st, (46degs)

MARS

Is at Solar Conjunction on the 4th.

JUPITER

Is the only bright planet on view in the morning sky, lying low down in the South-East in the constellation of Sagittarius. On the 14th Jupiter is 5 degs South of the Moon and on the 23rd is is only 43′ arc secs from the naked eye sky Omicron Sagittari.

URANUS and NEPTUNE

Both are not suitable placed for observations at this time.

PLUTO

This is so very faint it is out of the reach of all but the largest of amateur owned telescopes.


METEORS

THERE ARE NO MAJOR SHOWERS THIS MONTH BUT ALWAYS BE ON THE LOOK OUT FOR BRIGHT FIREBALLS.

COMETS

On the morning of July 23rd 1995, two amateurs discovered a new comet near the globular cluster M70, just South of the “Teapot” in Sagittarius. Alan Hale in New Mexico, and Thomas Bopp in Arizona were independantly using 16/17 inch reflectors Comet 1995 01 Hale-Bopp may? get to naked eye brightness by the end of next this year/early 1997 as seen from Britain

  • Comet (Hyakataki) C/1996 B2 is predicted to be very bright and circumpolar from the latitude of Liverpool.
    For most of March will remain in the constellation of Libra, best seen between 04-05:50am. It keeps to an almost vertical line, in terms of RA as it heads North. The Comet will be close to Alpha Librae – Zubenelgenubi on March 12th and near to M5 on March 20th/21st.
