Meetings

Meetings are held at the Royal Russell School, Coombe Lane, Croydon, Surrey CR9 5BX, start at 7:45 pm, and finish at 10 pm.

Our society is a registered charity. We do not charge a mandatory admission or membership fee, instead relying on voluntary donations by the following methods:

We try to structure the meetings to appeal to our members and guests of all levels, from beginner to expert. They normally consist of an introductory talk by one of our members, society news, or an observers section; then a refreshment break followed by the main lecture where the speaker presents a more in-depth talk. A small nominal charge is made for refreshments.

Friday

7th July 2017

For this meeting we welcome Dr Peter Grimley who will speak to us on: Discs and Rings. More details soon.

The earlier shorter talk will be by Tony Roberts.

Friday

23rd June 2017

Pauline Gorman will speak to us on: The Antikythera Mechanism.

The earlier shorter talk will be by Dave Burfoot who will update us on the Kenley Observatory.

Friday

9th June 2017

Konrad Malin-Smith will speak to us on: In the Beginning. From even before the Big Bang to significant events very soon afterwards (3 seconds) that shaped the Universe we see and know today, the Beginning was a very crucial time that nearly never made us.

Friday

26th May 2017

Jennifer Chan will speak to us on: Techniques to study large-scale magnetic fields. These involve using the polarisation of light and the epoch of reionisation.

Friday

12th May 2017

The Annual General Meeting of the society takes place this year on Friday the 12th May. The agenda, appendices and minutes of the AGM last year will be as handouts at the meeting. After the AGM we will include some astronomy , either in the form of news, photographs, short films or answering questions etc. if you would like to share anything, even if just a mention, please do so. There will be further information with other details soon.

As always the AGM portion of this Friday meeting can only be participated by members, whereas guests are welcome as usual during the rest of the meeting.

Friday

28th April 2017

Prof. Alan Aylward will speak to us on: From Daedalus to Dan Dare: The Feasibility of Interstellar travel.

Friday

16th Dec 2016

Our Christmas and last meeting of 2016, and as every Christmas meeting the format is different from the usual.

It's informal and the main feature, after the break, will be a fun event along various television style quiz programmes and based on the subject of astronomy, with rounds and questions. There will be some audience participation and Roy Easto will be chairing the quiz and asking the questions, which will also be illustrated on the screen with a combination of photos and videos.

As in previous meetings we ask members to bring some festive food and drink to share amongst ourselves, and the break will be longer than usual. After the break the food and drink will be moved into the room during the quiz.

Before the refreshment break there will be some astronomy news, events and observations, some from our own members.

Friday

11th Nov 2016

We welcome Melanie Davies FRAS, a space science communicator at Creative Space, who will present a talk on The Pleiades. Retrained in 2006 as a scientist (studied geoscience and astrophysics at university) she now works as a Space Science Communicator. Please note that this main talk will start at 8 pm.

The Pleiades, or Seven Sisters, (Messier 45 or M45), is an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

This will be after the refreshment break, before which there will be a short talk or some astronomy, pitched at a more basic level.

Friday

28th Oct 2016

The main talk this Friday is by Peter Edwards who will present the main talk on Imaging the Planets. Peter has been involved with high precision imaging of the solar system and his images have been widely displayed (The Sky at Night, magazines) as an example of what can be achieved, even with modest equipment.

This will be after the refreshment break, before which there will be a short talk or some astronomy, pitched at a more basic level.

Friday

14th Oct 2016

The main talk this Friday will be by Douglas Bateman who will speak on the History and Functioning of the Greenwich Time Ball. Douglas has been involved with precision timekeeping and the Royal Greenwich Observatory. He will cover the invention of the 'instantaneous signal' by Captain Wauchope leading to its construction in 1833, followed over the years, by many modifications. Douglas will bring us up to date describing his installation of electronic control in 1991 and now with a radio controlled clock that gives automatic changes to summer time and back.

Friday

30th Sept 2016

We welcome once again the experienced speaker Jerry Workman, winner of the 2009 highly prestigious Eric Zucker award (the Federation of Astronomical Societies [FAS] award for contributions to the astronomical community), and also a member of the Loughton AS, on the Smaller Bodies of the Solar System - Asteroids, Comets etc - and Pluto. These oft neglected bodies, due to their small size, are nonetheless significant objects.

Following the usual introduction and before the refreshment break the Short Talk will be by member Roy Easto, on the release of the first data set from Gaia, by even current standards an incredibly precise space observatory of the European Space Agency designed for astrometry.

Friday

16th Sept 2016

We have a variety of astronomical presentations. As an additional theme members are invited to 'bring and show', items or images, for any number of minutes (no notification is required, just bring and we'll show).

Following the usual introduction and before the refreshment break there will be some astronomy news, events and observations from around the world, some from our own members, and this is likely to be an extended version.

Friday

2nd Sept 2016

For this Friday we welcome the experienced speaker Paul Coleman, who will be taking us on an illustrated tour of the recent Solar Eclipse of March 2016 in Indonesia, a natural phenomena owing to a very fortunate coincidence. He will be bringing his own high resolution projector to show images at their best.

Following the usual introduction and before the refreshment break there will be some astronomy news, events and observations from around the world, some from our own members.

_____________________________________________________________


There are no meetings from mid-July to early September.


Details of our meetings are also available on the CAS Web Calendar found on the home page. Using this calendar you can set up email or SMS text alerts to remind you of the lecture times.

Friday

7th Apr 2017

Neil Phillipson will talk on: The Atacama Large Millimetre/Submillimetre Array. He will talk about ALMA (The Atacama Large Millimetre/Submillimetre Array) - the history and development, plus the science it will produce. He touches on the James Webb Space Telescope and why we need both.

Friday

24th Mar 2017

Mark Craig, director/producer of the Gene Cernan Biographic film The Last Man on the Moon, will feature stories about the making of the film and about the late Gene Cernan, the last astronaut to step off the Moon on the final Apollo 17 mission. Nine years in the making, Mark worked closely with Gene to ensure his story was faithfully recorded on film.

Friday

10th Mar 2017

Roy Easto will speak to us on: The Cassini Mission - a Celebration. Regarded by many as possibly the most successful space mission of all. We look back at more than 12 years of the probe orbiting Saturn and examine the hugely diverse range of objects it has recorded. Those delicate rings in all their splendour, Titan as seen on the surface, Iapetus, Enceladus and Mimas that vary so much in appearance and finally to the planet itself. Finally we take a look at the demise of Cassini as it dives into the planet later this year for a fiery end.

Friday

24th Feb 2017

Greg Smye-Rumsby will speak to us on: History of Longitude at Greenwich. A journey through the intricacies of finding a solution to longitude. There were a number of attempts at resolving this difficult task and many astronomers and scientist including self-made horologists that eventually opened the trade routes around the World.

Friday

10th Feb 2017

Peter Bull will speak to us on Cosmology: A Window through the Universe. A concise look at the history of the Universe, from the Big Bang to it's likely end, focussing on the four components of the Cosmos: Space, Time, Matter, and Energy, and how they interact.

Friday

27th Jan 2017

We welcome Dr E. Norman Walker, a retired professional astronomer, who will present a talk entitled: Recent Astronomical News and Discoveries. With ever increasing technology the pace of new discoveries, along with results produced after much observation and research, is ever increasing, and Norman will in addition give his own insight and interpretation using his career as a professional astronomer. This will also be a good opportunity to ask questions that will be answered from his many years of expertise and experience (so a good time to think of questions for the evening).

Norman will have plenty of material to occupy both sections before and after the refreshment break.

Friday

13th Jan 2017

The first meeting to start the New Year is by our own committee astronomer, John Berman, talking on the Detection of Meteors using Radio. Once again new technology today has made possible amazing results, and easily affordable in the 'pocket money range'. He will explain the equipment (set up at his home and now also at Kenley) the technique, and what can be achieved. Now meteors can be detected at any time of the day regardless of the weather; a true 24 x 7.

Before the refreshment break there will be a guide on what to look out for in 2017 by Graham Cluer.
