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.

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.

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