Wealden Astronomers monthly meeting and observing
The fourth Friday of the month from January 2026 to December 2026
Herstmonceux Castle
Halley Road, Hailsham, East Sussex, BN27 1RN
Wealden Astronomers meet on the fourth Friday of each month (with some exceptions, eg Christmas) at the spectacular Herstmonceux Castle.
On clear nights, if no other event is on the schedule, the group will also take advantage of the excellent observing and imaging opportunities that the dark location offers, away from light pollution sources.
Everyone is welcome, however please contact the Wealden Astronomers in advance if you would like to join them.
