The Society holds lecture evenings at the Royal Russell School, Coombe Lane, Croydon, Surrey CR9 5BX. These are held every other Friday during school term time and are open to the public. Click HERE for details of how to find us and what’s on.

We also have an observatory, near Kenley aerodrome CR8 5EP. There is also a clubhouse for visiting groups, a kitchen for hot drinks and wireless broadband internet (but no toilets). We try to open to the public (free, no need to book) on any Saturday night when it is clear. We notify HERE 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.


We sometimes open the observatory on other days/nights, for example for special meteor showers or for solar viewing.  Click HERE for any upcoming events.
