Croydon Astronomical Society

Croydon Astronomical Society present a series of talks on subjects related to astronomy on Fridays at the Junior School Hall of The Royal Russell School in Croydon.  We normally have one main talk of about 1 hour and a shorter talk of 30 minutes or less.

The talks start at 7:45 pm and are open to anyone.  There is no need to book; just turn up.

For details of car parking, a map and access by public transport click here.

There is no charge for the talks but there is a suggested donation of £3 per person to help cover the costs of venue hire and the speaker (larger donations are of course very welcome).  Refreshments are available for a nominal charge.

The talks programme is shown below.   Due to circumstances beyond our control there may be last minute changes.

We meet in a school with boarding pupils.  Please see the rules we ask visitors to follow.

Suspension of meetings at Royal Russell School and at the Norman Fisher Observatory.


Following revised recommendations from HM Government on the afternoon of 16th March 2020 that people should avoid social gatherings (such as in pubs, theatres, clubs) and not take unnecessary journeys the Committee has taken the decision to suspend all meetings of the Society both at Royal Russell School and at our Observatory.

I can only apologise that this action must be taken, but as you will be aware from press, television and the internet the situation demands that we follow the Governments advice. To do otherwise would be irresponsible and we would be failing in our duty of care to the public and our members.

We will attempt to maintain a “virtual” online presence here on our website, on Facebook and on Twitter but the exact nature of this will evolve over the coming weeks.

On behalf of the Committee we would like to thank you for your understanding and patience in these trying times. We wish all of you and your friends & families good health.
