Public Events

The Cardiff Astronomical Society (CAS) organises regular night sky and occasional solar observing events at its Observatory in Dyffryn Gardens or locations further afield. The events are either organised by CAS on its own, or run in conjunction with other organisations.

In addition, the Society's public outreach team has also answered many hundreds of questions about space and astronomy from our young visitors! Society officers also make visits to schools and scout meetings when requested.

Dark Sky Festival: Bannau Brycheiniog 20th September 2025

Always remain optimistic should be the motto of any astronomer living in the UK!

Despite a Yellow Alert for rain on the weather forecast and a strong wind we set up as we usually do and pressed on regardless.
In comparison with some events, we had luxury accommodation in a marquee with a dry floor!
And the public, other Societies, and groups to chat with for an interesting and enjoyable day.

We met with members of Bridgend AS, Usk AS, the Mid-Wales AS and renewed our knowledge of Curlews and the Hedgehog Helpline.
The local National Park staff were very welcoming and worked hard all day.
The CEO of the Park was also in attendance and thanked us for approximately 24 years of support and running events there. The new proprietors of the café were very generous supplying us all with a meal voucher. A hot meal was indeed very welcome.

Bob and Stephen were helpful as usual running a diagnostic session for one lady trying to get a telescope to work and the team helped many of the public to get started in this interest.
For those that wanted information, nobody went away empty handed. Tiffany’s Treasures were again very popular.
As for remaining optimistic – yes, the Sun did make an appearance, photos were taken in evidence for those of little faith! And yes, it did clear in the evening for Stephen to give one of his excellent tours of the night sky with tales of associated myths.

A long but very worthwhile day. And yes, the team enjoyed it and we’ll look forward to doing it all again but ordering up a warm, cloudless day and a clear starry sky first. We wish!

THANK YOU SO MUCH FOR COMING ON SATURDAY IN SUCH HORRID CONDITIONS.

You and your team never fail to amaze me with your generosity of time, experience and that “can do” attitude which is such an asset to our festival.

I do so appreciate your willingness from you and your lovely team who are happy so share their love of our dark skies.

Thank you also for helping to promote our festival which helps us greatly.
