THE PLANETS THIS MONTH.


MERCURY.

Mercury ends the rather poor evening apparition which started last month and swiftly heads towards next month’s inferior conjunction.


VENUS.

Venus, rising at 03h:00m in the middle of the month, passes very close to two stars at the feet of Gemini and close to another open star cluster (remember Venus passing the Pleiades last month?). On the 21st Venus lies 1°.5 south of M35 and between the 22nd and 24th passes 17′ north of eta and mu Geminorum. After this month Venus starts to head back towards the Sun.


MARS.

Mars also lies in Gemini and also passes by eta and mu Geminorum, on the 11th and 14th respectively. On the 9th Mars passes just south of M35 but lies a mere 15° away from the Sun. It will be a couple of months before the red planet really starts to show again in the morning sky.
MARSWATCH – latest observations of the red planet.


ASTEROIDS.

  • Iris is at opposition on July 20th in Sagittarius Mag 8.9
  • Pallas is stationary in Pisces on July 26th at Mag 10.0
  • For More information on Asteroids Click Here.

JUPITER.

Jupiter is approaching opposition and is showing a disk with an apparent diameter of 46″ by the end of the month. Compare this with a measly 33″ at the start of the year and you will see that it is time to get the telescopes out!

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 starting to become better placed for observation, rising before midnight at the end of July.


URANUS and NEPTUNE.

Uranus is at opposition next month and owners of telescopes maybe able to see a tiny disk using a high magnification. Uranus is bright enough to be visible in binoculars.

Neptune is much fainter than Uranus and is more of a challenge to locate and observe. It is at opposition on the 23rd.

PLUTO.

Pluto can be found on the border of Ophiuchus and Scorpius, above and to the right of the mag 2.6 star Zeta Scorpii. The best time to look for the planet is around New Moon. The dates below will be a guide for planning observations.

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

Thomas Glazebrook Rylands and The 5″ inch Cooke Telescope

October 1993 marked the 100th anniversary of Liverpool Astronomical Society taking possession of the 5″inch Cooke equatorial telescope. Which at present is still situated in the observatory on the roof of the (NMGM) Liverpool Museum. The 5″inch Cooke telescope was donated to the Society by:-

Mr. Thomas Glazebrook Rylands

Mr. Thomas Glazebrook Rylands, 1818-1900

He was the son of John Rylands, a wire mill owner in Warrington. On his fathers retirement Thomas Rylands, together with his two brothers, Peter and John the younger, took over the running of the wire mill and made the family business one of the most successful in the North West. Thomas Rylands had many interests outside the running of his fathers wire mill. one of which was astronomy. Astronomy attracted and fascinated Thomas Rylands early in his life, even before he possessed a telescope. In 1865 at Heath House, one of his many Warrington residences, he built a wooden observatory of two storeys, with a revolving dome. It was there that he placed his newly purchased 5″inch equatorial telescope and a 2″inch transit instrument, both of which were made by Cooke of York. Soon he was able to make frequent observations as and when the Mersey weather would allow, and he would send these observations to the Royal Astronomical Society, having become a fellow in 1866. However his observing nights were often disturbed by boys throwing stones into the open shutter of the dome, to the peril of both observer and instrument. As soon as these “bombardments” began Rylands was forced to close the shutter and wait patiently until as he himself stated ” the enemy raised the siege”.

In 1871 he built a new house at Highfields in Thelwall, and constructed a new observatory consisting of a dome on top of a high tower, which in time became a well known local landmark. By 1888 old age together with cold winter nights may have forced him to give up his observational astronomy, and at the Liverpool Astronomical Society Meeting of December 10th 1888 a letter was read out by the then Hon Secretary Mr W.E.Rowlands, in which Rylands propsed that the society should become the benefactor of the 5″inch Cooke telescope, and other instruments. His vast library of books and other papers, he donated to the University of Liverpool In May 1889 he also contacted the Chairman of the Free Library and Museum sub-committee, Sir Henry Higgins. This contact lead to the City Council Parks, Gardens and Improvements Committee discussing, at its meeting on July 3rd 1889, the building of an observatory in the city centre to house the Cooke 5″inch telescope. In 1892 the company of Raffle & Campbell had won the contract to build an astronomical observatory on top of the Liverpool Nautical College, which at that time was located at the Liverpool Royal Institute building in Colquitt Street. Discussions between the then Liverpool Astronomical Society Council and the City of Liverpool Council resulted in a formal agreement being signed. The minutes of the City Council Library Museum & Arts Committee records:

August 31st 1893:-“That the Lord Mayor be requested to affix the corporate seal to the agreement with the Liverpool Astronomical Society as to the deposit of an equatorial (telescope) in the observatory at the Nautical College”.

Sadly there is no trace to-day of the agreement document and the City Council Solicitors believe that it may have been destroyed in War time bombing.

At the Society meeting held on October 31st 1893, Mr Rylands, who was for many years a member of the Liverpool Astronomical Society appointed trustees of the 5″inch Cooke telescope. The handing over of the telescope may have taken place some years before, but the Society minute books recorded the society taking possession of the 5″inch Cooke in October 1893. The observatory together with the telescope were to relocate to their present home sometime between 1899 – 1901, when a new bigger Nautical College was opened in the newly built Central Municipal Technical College building,(now part of NMGM “Liverpool Museum”), which opened to students in October 1901.

The rest is as they say is “LAS history“, but what became of Thomas Rylands?. Sadly not long after the above events he contracted influenza from which he never made a full recovery, and he died in his sleep on February 14th 1900 at his house Highfields, Thelwall. The House can still be seen to-day, but sadly his observatory has been pulled down.

THE PLANETS THIS MONTH.


MERCURY.

Mercury is at superior conjunction on the 10th but swiftly moves away from the Sun to edge above the north western horizon in the evening. The apparition is not a favourable one, as seen from Liverpool, however with the planet a mere 2°5 above the horizon between June 30th and July 5th about an hour after Sunset


VENUS.

Venus gives the impression that it is ending a short morning apparition as it hugs the Eastern horizon before Sunrise, Its unisually shy appearance changes soon though and it will be seen slightly higher each month. On the 23rd at 00h Venus is 2.5° north of the Moon and on the 28th lies just 15′ north of Saturn.


MARS.

Mars is at solar conjunction this month and lies directly behind the Sun as seen from the Earth on the 12th.

MARSWATCH – latest observations of the red planet.


ASTEROIDS.

6 Hebe is at opposition on the 13th in the constellation of Ophiuchus at Mag 9.4.
Melpomene is at opposition on the 23rd also in Ophiuchus at Mag 9.8.

JUPITER.

Jupiter rises at 01h:30m in the middle of the month and so should lie quite high up in the upper left hand portion of Capricornus by the time the Sun approaches the Eastern horizon. On the 17th at 14h:00m Jupiter is 1.°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 too is heading away from the morning twilight, rising at 02h:30m in the middle of the month. On the 19th Saturn is 3° north of the moon.


URANUS and NEPTUNE.

Uranus can be found low in the South-Eastern sky in the constellation of Capricornus, with Neptune just south, outside the same constellation.

The Total Solar Eclipse Of 26th February, 1998: A Liverpool Astronomical Society Perspective –

by Dr. John Eric Jones

The LAS have been sending members on total solar eclipse expeditions since the 1880’s. One saros ago no less than 15 members went to Kenya to observe approximately 4 minutes of totality. This was a pivotal eclipse. Although there was already much experience of eclipses amongst some members, it was the first eclipse at which several experiments were deployed which have continued regularly to the present day.

This year a dozen members went to sites in Venezuela and Curacao to observe the eclipse of February 26th. The great majority went to a beach at Knipbaai in the far North-West of Curacao. At this location, apart from photography, the two main experiments were timing the duration of totality and attempting to video shadow bands if they occurred.

Shadow bands are notoriously difficult to photograph or film. In 1976 Graham Broadbent of the LAS obtained photographs of them at an eclipse in Zanzibar as displayed on a standard 1 metre diameter shadow band disc. The disc follows the practice of Edgar M.Paulton and Richard L.Feldman. The latter studied shadow bands for over 40 years (see Sky & Telescope, Vol 39, No2 February 1970 pg 132-133). In recent years Eric Strach (or rather Mrs M.Strach!) took on the onerous task of hauling shadow band discs across the globe to eclipse sites usually without success. A faint video image was recorded in 1991 but this year marked a crowning achievement as distinct shadow bands were recorded both before and after totality. Video frames and a report have appeared on the LAS web site through the courtesy of LAS member Mr Gerard Gilligan who arranged processing of the video at Liverpool University.

Unfortunately Eric Strach’s vocal signals at 2nd and 3rd contacts were drowned on his tape by shouts of excitement of the surrounding observers. However another timing experiment was performed by LAS member Eric Jones at a different location. Because of this very fact of background noise, Eric Jones accepted an invitation from Professor John Parkinson (Sheffield Hallam University) to view the eclipse from a quiet site at the Knip Landhuis ( a rather elegant Plantation house roughly 2km from Knipbaai) Another possible location was next to the official public viewing site at Watamula in the very north of the island where under Professor Parkinson’s direction a gigantic wall of cargo containers, stacked two high, had been positioned to protect observers from the constant trade winds which sculpt the local low thorn bushes into fantastic shapes.


However as eclipse day dawned with local cloud cover and rain it was decided to change site as Knip Landhuis was under a plume of clouds generated by the local St Cristoffelberg mountain. It was therefore decided to use a villa at the Kadushi Cliffs Resort just north of Westpunt. As we set up, our activities were filmed by the BBC for a possible program to be broadcast in the UK before the 1999 eclipse. Colin Davies and Eric Jones occupied the balcony of the villa whilst the BBC and John Parkinson’s group occupied the patio in front.

Fortunately as the morning proceeded the sky cleared and by the time of the eclipse the sky was perfectly clear. We were confident that the sky would be clear, as a ship (The Holland- America Line Statendam) anchored near us just a few hundred metres offshore. They presumably had weather satellite systems and so the fact they had selected our location meant we were in a good spot.

We viewed the usual pre-eclipse phenomena. The BBC filmed crescents on the balcony floor underneath a plastic plant held high in the air by Colin. Shortly before totality a parrot-like bird crashed into the balcony next to Colin and the video camera. The bird was obviously disoriented by the eclipse and so Colin tried to soothe it. About 30 seconds before totality the cry “shadow bands” went up and a quick glance revealed a magnificent display of shadow bands visible not only on a small shadow band screen next to me but also on the white-washed walls of the villa.

In addition to the timing experiments a programme of still photography was carried out. In fact it proceeded so well that an extra bulb exposure was added. It is easy to lose track of time during totality so a series of electronic alarms had been set up as a reminder. This allowed a full 50 seconds of spare time to look around to enjoy the near-minimum style of corona, the nearby planets and the environment which was enlivened by the explosions of fireworks.

Three different timing methods were used:

  1. Motorised electronically controlled camera.
  2. Video.
  3. Vocal signals recorded onto tape together with time signals.

They all worked perfectly.

We also received further data from other locations. At Knipbaai the President of the British Astronomical Association, Martin Mobberley took a video which provided an extra timing. Also at the same location Mr. Shelley Fey who is an experienced eclipse observer and whose timings have been a valuable supplement to our own data at previous eclipses provided a further measurement of the duration of totality.In fact we also received a video with associated GPS measurement from yet a third location on the island of Curacao.


Timing experiments, when analysed, can yield information on possible solar diameter variation. The analysis of these timings is now almost complete but they all give a very consistent picture that the solar radius was about 0.4 arc-seconds larger than the adopted IAU value at the time of the eclipse. This is from 6 different measurements using 4 different techniques at three locations. The consistency was very satisfying.
There was one final bonus after all the excitement of the eclipse itself. After most people had returned home, Colin Davies and Eric Jones lingered on in Bonaire. At approximately 9.17pm local time on the 14th March they were treated to an occultation of Aldebaran close to the southern limb of the Moon which was recorded on video. This brought a very successful eclipse expedition to a close.
