Public talks

The Society holds public talks about astronomy at Trinity School, Croydon CR9 7AT approximately every other Thursday during school term time. Our talks are open to all. 


The talks are usually held in the Staff Canteen – see Talks location below for directions.  Very occasionally the school may ask us to use another room and, if this is the case, details of the alternative room will be posted on this page. 


Talks start at 7.30pm sharp and usually finish by 9pm including a break for refreshments. There is no charge but we suggest a donation of £3 per person towards society funds (larger donations are, of course, very welcome).  Refreshments (tea & coffee) are available for a nominal charge of 50p.  We accept cash and contactless (minimum £1) payments
