Fortnightly CAS Social (Tuesday Evening) via Zoom (Members Only)
Once a fortnight (same week as Thursday talk) on a Tuesday evening from 19:00 to around 21:00 we hold a social get together on zoom where we chat about both astronomical and non-astronomical subjects, have a quiz and have presentations by members. The presentations are usually on either member's hobbies or their travels but can be on anything they think others will find interesting.
Why not come along one week to see what you think. You do not need to stay for the whole session and people often arrive late or leave early because of other commitments. It is very informal!
To register your interest complete the ContactUsForm. Please include your Membership Number and you will be sent a link to the next session.

Museum After Dark 26th Feb 2025
After Dark - well it's what we do! Except when it's safely looking at our nearest star of course.
An annual event for families and people of all ages. Prize for the longest queue in the World must go to Bob Love! A very popular man and we hope his voice has recovered by now as he didn't stop teaching all evening.
Our tablecloth demonstrated another useful function - Name that Planet' for a prize which was a pocket star chart.
And Tiffany sold out of some of her Treasures with a record amount taken! Well done to Denise, Tiffany, and Joan with their public engagement, Kath for helping to set up, and Mike and Edward with their supervision and care of Buzz.
And last but not least many thanks to Lin Love for the delicious cakes which kept everyone going!

PART 3: THE CARDIFF ASTRONOMICAL SOCIETY
Introduction to CAS
The Cardiff Astronomical Society (CAS) is a thriving society located in South East Wales. It has been in existence for over 45 years and is one of the largest amateur astronomical societies in the UK. CAS provides a range of facilities for both Society members and the public at large including a varied programme of talks on Thursday evenings (except in August) at the Physics and Astronomy Department of Cardiff University. In addition, regular night sky (and occasional solar) Observing Sessions are held at the Society's own Observatory at Dyffryn Gardens.
Our members come from all walks of life and their knowledge of astronomy ranges from complete beginner to advanced. You don't need any specialist knowledge to join us and neither do you need to own a telescope or binoculars. It's also possible to try us out before joining!
More details about the Society and what it does are available here
We are keen to get more Society members on board to assist with the running of CAS events - please see here how you can Help Us
JOIN OR SUPPORT CAS
Come and join some of the Society's members at one of our talks or observing events. We promise a warm and friendly welcome for all. Only £18/£3/£24 per annum for Adult/Junior/Family membership also means you can make use of our Library
Gift Aid
CAS is registered for Gift Aid. This means that, if you are a UK taxpayer, we can claim back the standard rate tax on subscriptions (and on any donations) giving an effective 25% boost to the amount the Society has received. However, in order to reclaim these monies from HMRC, we need all members who pay tax to complete and return a Charity Gift Aid Declaration form. Please note that if you have paid your subscriptions by PayPal, you will have already been asked if you would consent to those subscriptions being Gift Aided - but we still need a completed Charity Gift Aid Declaration form in order for us to reclaim the tax paid as Gift Aid.
If you are eligible, please take a form (using the button opposite) and then complete it and pass it to us at one of the fortnightly talks or send it to CAS by post or email (see the bottom of the form). Thank you for your help!
