It is hoped to organise one or two lectures with visiting speakers during the year. Some of these lectures are held in conjunction with the Jersey Astronomy Club and the Sark Astronomical Society.


The Astronomy Section welcomes a limited number of group visits, by prior arrangement.  See our introduction page for details.


Members’ annual barbecue and Perseid meteor count will be held at the Observatory around 12 August (date to be announced).


The Astronomy Section’s Annual Business Meeting was held on Tuesday, 31 January 2017 at the Observatory. Officers were elected, and decisions were made about purchase of equipment, activities for the year, etc.



This popular six-week introduction to astronomy is being run at the Observatory on Thursday evenings from 02 February to 09 March 2017. The WEA brochure is available at the WEA website. This is the 16th year of the course. As usual it is being run by members of the Astronomy Section of La Société Guernesiaise, and is fully subscribed. We are grateful to the WEA for a donation to the Astronomy Section’s funds for running this course.
