THE PLANETS THIS MONTH.


MERCURY.

Mercury is very well placed in the evening sky during March. Look to the West between the 17th and 23rd and you will find this bright planet over 10° above the horizon at the time of Civil Twilight. This Table should help in observations. On the 10th Mercury is just under 1° North of Mars.


VENUS.

The Altitude of Venus stats to decline slightly as the angle of the ecliptic changes with respect to the horizon. It also starts to dim slightly but it should be visible almost up until the time of Sunrise. On the 24th at 19:00 Venus is 28′ North of the Moon.


MARS.

Mars is briefly associated with Mercury this month. This practically, may be the last opportunity of locating Mars until after solar conjunction in May.

MARSWATCH – latest observations of the red planet.


ASTEROIDS.

Vesta is 0.1° South of the Moon on March 2nd, and 1.2° North of Moon on March 30th.
Juno
is 0.9° North of Moon on March 13th. It reaches opposition on March 19th at Mag 9.1.

For More information on Asteroids Click Here.


JUPITER.

Jupiter will soon reappear in the dark sky after last month’s solar conjunction but before then there is an interesting daylight event to be aware of. At 11h:00m GMT on the 26th Jupiter will be occulted by the bright limb of the thin cresent Moon. The Moon will only be 24°: away from the Sun so be careful when sweeping the sky as you don’t want the SUN by accident! Looking at the unshielded SUN directly WILL CAUSE PERMANENT EYE DAMAGE.

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 approaching solar conjunction and is unfavourably placed for observations, setting at 19h:30m at the end of the Month.


URANUS and NEPTUNE.

Both outer planets are starting to appear in the morning sky but will be better seen in April and May.


PLUTO.

Pluto will be out of view until the end of March.



METEORS.

There are no showers during March.


 

COMETS.


OCCULATIONS.

  • March 3rd at 21h:21m Disappearance of 5 Tauri.

Shadow Bands Recorded on Video!

A Report by Eric H.Strach, F.R.C.S., M.Ch.Orth.,
Hon. Vice President,
Liverpool Astronomical Society

Drawing of Shadow Bands as seen from Sicily, Italy on December 22nd, 1870

Drawing of Shadow Bands as seen from Sicily, Italy on December 22nd, 1870

Members of the Liverpool Astronomical Society have been trying for many years to capture the elusive bands on photographs, cine film and more recently on camcorders.

I have first seen them at the eclipse of 1976 in Zanzibar. At that time Graham Broadbent constructed a special screen which he erected so that the rays fall vertically on it. It was an early morning eclipse, the sun and moon were only 8° above the horizon.

We have seen the bands on several subsequent eclipses but failed to record them on photographs or cine films. After Graham left our society I tried to continue his work and inherited his shadow band screen, and took it to Java in 1983, to Sumatra in 1988 but I did not succeed to record the bands. In 1990 was clouded out in Finland.

I had better luck on 11th July 1991 in the Baja peninsula: I mounted the camcorder to a fitment beneath the apex of my tripod so that it pointed downwards to the ground, where the screen was placed at this mid-day eclipse with the sun almost overhead. The bands were seen but only with the eye of faith could one possibly make out the bands in the recording and I was never convinced.

I had to miss the next three eclipses but I tried the experiment again at Knipbaai Beach in Curacao on 26th February 1998. The sun was again high at the time at an altitude of 60° so I used the same arrangement. The bands were clearly seen by most observers and I just hoped that my new camcorder fitted with a “high 8” video cassette will succeed.

The camcorder was started 4 minutes before second contact and a one second time generator gave signals which changed pitch every half-minute. Thus the signals and any comments were recorded for later analysis. I used a polaroid filter combined with an UV filter. My recording was stopped some 4 minutes after third contact.

I suppressed my curiosity and refrained from playing back what I recorded. Only on the day after arriving home did I play back the video and there was no doubt whatsoever that the shadow bands were there, visible for 32 seconds before totality and 27 seconds after totality. However, the bands remained visible for over one minute.

They moved rapidly across the screen in a direction from E to W before second contact and from NNE to SSW after third contact. The bands were disposed at an angle of 70° to the E-W line before 2nd contact and at 30° after 3rd contact – as illustrated in the diagram. Slow motion studies of the video showed that the bands merged at times and on occasions they seemed to move in opposite directions, undoubtedly a stroboscopic effect.

The question arises why I succeeded this time and not on any previous attempts. Perhaps the use of the polaroid increased the contrast, I doubt whether the UV filter had a similar effect. The most probable explanation is that the bands were more pronounced this time. Further attempts should be made to record these bands in the future but it may take several eclipses and thousands of miles of travel to get results. It would be far better to have a battery of like-minded observers who would use different systems and filters to establish the optimal method.

The images display on this page were obtained by a frame grabber and were then image-processed. My grateful thanks for their help in this process go to Mr Andrew Trafford of Liverpool University and to Gerard Gilligan and Robert Johnson of Liverpool Astronomical Society.

Pex Hill Visit of North East Astronomical Societies – 22nd August 1998

Report by Robert Simpson

Inside Pex Hill Visitors' Centre (now the Leighton Observatory). Date unknown but likely 22nd August 1998 or 20th March 1999

On Saturday, August 22nd 1998 a group of astronomers, representing six North East of England astronomical Societies, came to Liverpool to meet members of Liverpool A.S. The Previous Wednesday night was spent preparing the William Brown Street Observatory. That entailed putting up displays and generally tidying up the room so that everything would look nice when the visitors arrived.

All happy Astronomers

When they arrived at 12:00 noon we took them around the NMGM Liverpool Museum to show them some astro photographs and we talked to them on an individual basis to get to know them. After this the visitors were taken to the NMGM Liverpool Museum Planetarium, the best outside London. They were shown two programmes, the first was about asteroids and comets and the effects on the Earth if one of these were to impact. The second, called Night Watch, showed the night sky as seen from Liverpool for the coming months.

The Planetarium shows were followed by a visit to the City Observatory. Ron Kelley gave a talk to the visitors about the history of the LAS, while Geoff Regan showed them the observatory room and the 5inch Cooke Telescope. The visitors were then taken to the NMGM Conservation Centre, also in the City Center, to see the replica of William Lassell’s 24 inch telescope built in 1996 to celebrate the 150th anniversary of Lassell’s discovery of Neptune’s large moon Triton.

Solar observing

A coach trip to Pex Hill observatory was next on the agenda. When we arrived tea, coffee and biscuits had been laid on for everyone. Telescopes, belonging to Liverpool A.S. members, were made available for everyone to use to observe the Sun, and then we looked at some astro slides, and were given a talk by Liverpool A.S. member Morad Ghorbal.Geoff Regan and David Galvin showed the visiting group around the observatory at Pex Hill, which houses the LAS 16 inch Robertson Newtonian Telescope, they explained the work that has been done and what still needs to be done on the dome,telescope and its mount.

David Galvin also demonstrated his work on collecting weather satellite images “Live” from space. Our visitors left at about 6:00pm and we just tided up the room – everyone had a good day and I hope that one day we can organise a return trip to the NorthEast sometime soon.

THE PLANETS THIS MONTH.


MERCURY.

Mercury is at superior conjunction on the 22nd an will therefore be out of view.


VENUS.

Venus shows nicely in the South East, rising at 05:09 on the 20th – over two hours before Sunrise. On the 23rd Venus is 2.5° North of the Moon.


MARS.

Mars is now in Aquarius and on the 9th lies a mere 31′ South of the naked eye star Lambda Aquarii Soon the red planet will be lost in the evening twilight and its 4.2″ diameter disk makes it a poor telescopic object.

MARSWATCH – latest observations of the red planet.


ASTEROIDS.

Pallas is in conjunction with the Sun on the 14th.

JUPITER.

Jupiter is at solar conjunction on the 23rd, and will reappear in a dark morning sky in April.

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 sets at 21:15 at the end of the month and so makes a fine evening object in the constellation of Pisces. On the 1st Saturn is 1° North of Moon.


URANUS and NEPTUNE.

Both outer planets are moving out Solar conjunction this month, and are unfavorable for observations at this time.


PLUTO.

Pluto will be out of view until the end of March.



METEORS.

February 3rd and 13th Alpha Aurigids ZHR is 12 per hour. (Unfavourable)

THE PLANETS THIS MONTH

MERCURY.

Mercury is visible as a morning object but will rapidly head back towards the Sun. This Table gives more details. (link removed as URL is invalid)


VENUS.

Venus is confusingly visible both as an evening object and a morning object this month, though obviously not at the same time!. For the first half of the month Venus finishes off its evening appartion which began last year. It will be found in the South West shortly after Sunset. Rapidly passing inferior conjunction on the 16th it starts a morning apparition soon after whilst travelling through the constellation of Sagittarius. Look South East (azimuth 128°) at 06:40 0n the 27th to find the Moon lying 4° to the South.


MARS.

Mars sets at 19h:00m by the end of the month and is only 23° away from the Sun in the constellation of Capricornus. On the 21st, at 05h:00m, Mars is 11′ South of Jupiter but as this very close conjunction occurs below the horizon as seem from Liverpool, try and observe the evnings of the 20th and 21st to see how the two planets have changed their relative positions in a short space of time.

MARSWATCH – latest observations of the red planet.


ASTEROIDS.

Ceres at mag 9.2 can be found in Aquarius and Vesta at mag 7.8 in Cetusduring the month.

JUPITER.

Jupiter is heading towards Solar conjunction next month, rapidly descends into the evening twilight, passing 2.5° of the Moon on the 1st and 1.5° South of the Moon on the 29th.

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 higher in the sky than both Jupiter and Mars and lies due South at 18h:30m at the start of the month. On the 5th the Moon passes 1° to the North.


URANUS and NEPTUNE.

Both outer planets are at Solar conjunction this month, and are unfavorable for observations at this time.


PLUTO.

Was in conjunction with the Sun on November 27th and will be out of view until the end of March.
