Stour Astronomical Society

Newsletter May 2003

Hello, and welcome to our first newsletter which we hope to produce regularly.

 

The newly formed Stour Astronomical Society has arranged to meet on a monthly basis in the Jubilee Room of Cavendish Memorial Hall on the first Tuesday of every month at 7.30 p.m.

 

At each meeting an illustrated talk will be given either by Dr. Kevin Marshall or by a guest speaker. Dr. Marshall is a lecturer with the University of Cambridge board of continuing education and is a founder member of the Stour Astronomical Society.

 

The Society was founded this year to provide a focal point for amateur astronomers of all levels of interest and ability to meet and share their enjoyment of the night skies. It is anticipated that members will be drawn from nearby towns and villages in the Stour Valley area.

 

It is hoped that at future meetings some observation will be possible on clear nights and members are invited to bring telescopes or binoculars when weather conditions permit.

 

 

 

 

 

 

 

 

 

The first meeting was held on 4 March with a talk on the Solar System and at the following meeting on 1 April, Dr. Marshall presented "From Technology to the Stars", an overview of observational techniques from Galileo to the present day.

The talk for 6th May will be on the "Constellations" and that of 3rd June will be "Observing the Night Sky with Binoculars and Small Telescopes". Future subjects will include :-

*    Moon

*    Sun

*    Stars and Galaxies

*    Asteroids, Comets, Meteors

*    Deep Sky Objects

*    Black Holes, Quasars, Super-Novae

*    More Constellations

*    Telescopes & Observing

*    History of Astronomy

*    Cosmology, Space & Time

*    Radio Astronomy

*    Satellites & Space Craft

 

But please feel free to suggest additional topics of interest.

The S.A.S.

The Stour Astronomical Society (S.A.S.) is a non-profit organisation. The annual subscription is £12.00 payable on 1st April each year. This will entitle members to attend the monthly meetings and will include occasional newsletters and information sheets. Guests and visitors are welcome to meetings at a charge of £1.50 per meeting.

Our aim is to break even on the costs, the most significant of which is the hire of the meeting room.

Trips and other activities may require additional contributions but these will be announced where appropriate.

We expect to hold the first A.G.M. in April 2004 and a statement of accounts will be made available to members.

We will need additional volunteers to assist with committee work in the future and would certainly appreciate assistance from 7.15 p.m. on the meeting evenings to put out chairs and to tidy up afterwards – thank you.

 

 

 

 

 

 

 

The Night Sky

Each month we will be drawing members’ attention to the interesting objects in the night sky for the time of year. This may include the positions of planets, prominent constellations, meteor showers, comets, eclipses and transits.

For example, May brings three significant phenomena for the early risers !

On 7th May, starting at just after 6.00 a.m. and lasting for around 5 hours, the planet Mercury will pass in front of the Sun. This is known as a transit and will be visible from the U.K. Mercury may be seen as a small black dot crossing the disk of the Sun.

SEE WARNING NOTE

On 16th May, there is a total eclipse of the Moon, again visible from the U.K. Commencing at around 3.00 a.m. as the Moon is close to setting on the South West horizon. Totality starts at 4.14 a.m. with completion by 5.06 a.m., just as the Sun rises.

The Moon is safe to view through telescopes and binoculars, albeit rather bright at full Moon, but remember, do not swing the instrument round to look at the Sun ! SEE WARNING NOTE

On 31st May, the Sun itself will be the subject of an eclipse. This will be visible as an annular eclipse in the North of Scotland and Islands and as a partial eclipse at Sunrise in other parts of the U.K.

An annular eclipse occurs when the apparent diameter of the moon at eclipse is smaller than that of the Sun.

SEE WARNING NOTE

 

 

 

Jupiter still dominates the evening sky and is a superb object for the beginner. The disk is very clear together with its bands and it should be possible to see several of its moons with even a modest telescope.

Some star charts for May are included with this newsletter.

Jupiter remains a bright object in the evening sky during June but the lenthening hours of daylight will reduce its contrast against the twilight.

Mars, however, increases in brightness very rapidly over the course of the month. Starting the month in Capricornus and moving on to Aquarius eventually appearing near to midnight low in the South East. Observers with large aperture telescopes at high magnification may be able to detect the disc of the planet and possibly, martian storms permitting, the polar ice caps.

Also appearing in these two constellations are Neptune and Uranus respectively, although as very faint objects in the early hours. Probably lost in light pollution and haze during June, Uranus in particular is likely to be more easily visible in July.

WARNING NOTE

On no account should the Sun be observed directly or with a telescope or binoculars as this will cause permanent damage to your eyesight.

The best method is to project an image of the Sun onto a white card but first ensure that your telescope’s optics, particularly the eyepiece, will withstand the focusing of the Sun’s rays.

 

Light Pollution

One of the major obstacles to present day astronomy is the presence of light pollution from street lighting, security lights, floodlit buildings, car parks, factories and sports stadiums. Haverhill and Long Melford are particularly affected by the latter two and we even had to choose our meeting evening carefully to avoid the floodlights of the Cavendish football pitch.

National Astronomy Week

This has been organised for the week of 23-30 August 2003 to coincide with the time when Mars is its closest to Earth within recorded history. More information nearer to the date or visit www.astronomyweek.org.uk

 

Publications

Probably the best U.K. monthly for amateur astronomers is "Astronomy Now" but there are several other excellent magazines available at good newsagents. From time to time we will draw your attention to books and in future it may also be possible to set up a lending library as funds permit.

One excellent book for the beginner is "Turn Left at Orion" by Guy Consolmango & Dan M. Davis and published by Cambridge University Press, ISBN 0 521 78190 6 HB. It provides a very easy to follow guide to finding constellations and objects in the night sky throughout the year.

Its worth noting that we can obtain discounts for all Cambridge University Press publications – let us know what you need ! www.cambridge.org

 

The F.A.S.

We are the S.A.S. but there is also a thing called the F.A.S., The Federation of Astronomical Societies. It is our intention to affiliate the S.A.S. to the F.A.S. and thereby to benefit from its resources, including the annual conference in the Autumn – more news of this later.

A Name

Rather than just "Newsletter" it might be nice to have a name for this publication. Please give this some thought and let us have suggestions over the next few meetings.

Spread the Word

If you like what you have seen so far, please tell your friends and welcome them along to future meetings.

And Finally !

From Our Chairman

Hello,

Just a few words to welcome you to the Stour Astronomical Society.

The Stour Astronomical Society aims to fill a void in the county of Suffolk where there is a lot of interest in astronomy but very few places to go and meet other amateur astronomers and listen to talks given by expert speakers, receive advice on what equipment you perhaps would like to buy and what to observe in the night sky. At the moment one either has to travel over to Cambridge or Orwell, both having first-class astronomical societies but nevertheless quite some distance away. So please come along on the first Tuesday of the month to meet fellow amateurs and to deepen your love of the wonders of the night sky. And please don’t forget to tell any friends you have who might also be interested in astronomy!

Don’t forget either to observe the total lunar eclipse visible in the early hours on May 16. Despite the low altitude of the Moon above the horizon, we should be able to see most of this beautiful natural phenomenon. The eclipse starts at 01 hr 05min, reaching its maximum at 03hrs 14mins.

So have a good month observing the night sky!
