Croydon Astronomical Society
est. 1956

Welcome to the Croydon Astronomical Society

Our society has two main activities and events -

the regular school meetings for talks and our observatory for visits

Here are details of all:

Meetings and Talks  - Friday 22nd March: Roy Easto - Neutron Star Mergers.

Kenley Observatory visits  - next opportunity: Saturday 23rd March from 7:30 pm.


 • The images to the right show the most recent by our members, mostly in the south London area. See the gallery for more details of these and other images.

 • Photo Gallery updated 7th August with updates to existing galleries. Galleries can now be viewed across many browsers and devices.

 • The Latest News page has new items (updated: 8th December).

 • The Events page has new events (updated: 8th December). Observing events at Kenley, past and for the rest of the year.

 • The Observing page now has links to what can be seen in the night sky right now, choosing a telescope, online calculators etc.


We also have an observatory, above, near Kenley aerodrome CR8 5EP. There is also a clubhouse for visiting groups, a kitchen for hot drinks and wireless broadband internet. Schedule meetings here are on some Friday nights for members only, and any Saturday night it is clear for the public as well. We notify just below when this is the case. Parking (observe restrictions) is nearby, off-road in Hayes Lane just a couple of hundred metres to the south at the Royal Air Force Kenley Tribute.


Our observatory at Kenley unfortunately will not be open this Saturday 16th March, due to unfavourable weather. It was last opened on the 23rd February when over 50 people visited. The next opening opportunity will be next week - decision will be made in the early afternoon. The scheduled group visit will still go ahead as planned.

Visible in the night sky are the planets Mercury, Mars, Uranus, Venus (morning sky), and many deep sky objects. Comet 46P/Wirtanen is now well placed, viewable in binoculars and telescopes.

All Saturdays are open to the public (when open) unless otherwise stated (no need to book, just turn up). Details here.

Details of the last regular openings are here, along with forthcoming Events.

An important note on the weather. The Observing page shows what is visible this night/week/month.


Founded as the Croydon Group of the Junior Astronomical Society on 5th May 1956, and becoming the Croydon Astronomical Society in 1965.

More information on dates and our lectures are in the Meetings page. Lectures start at 7:45 pm and finish around 10 pm. There is free parking and very good public transport links.
