Welcome to The Bristol Astronomical Society (BAS). Based in the South West of the UK, BAS is run by amateur astronomers as a non-profit making educational charity. We are dedicated to exploring and explaining the splendours of the night sky and all aspects of astronomy for both our members and the public. We are open to all, from the most knowledgeable to those merely curious.

With over 120 members and weekly meetings, we are one of the most active Societies in the UK, supporting a variety of interests ranging from observing, imaging, sketching and (of course) the armchair. We have a great 2015-2016 programme of talks with regular guest speakers. The Society has its own Observatory and supports regular outreach across the city. Importantly, we enjoy the company of others as we share these interests.

On this website you will find more details about our events, where we meet, how you can join and news on what we get up to. Feel free to browse around the site and if anything looks interesting and you'd like to know more, then visit our Contact us page. You can even email us your astronomy questions and we'll do our best to find you an answer! For those who are interested we also offer free public viewing at our Failand Observatory on Saturday evenings. Come along (follow the information given on the Observing Tabs) and let us show you the Bristol night sky.

For more information on the society, check out our FAQ page.
