The Federation of Astronomical Societies (FAS) is an international union of astronomical societies formed in 1974 and will be celebrating its 50th anniversary in 2024. Its motto is "Supporting UK Astronomy", and there is also one member society from Spain. As of November 2021, it has over 200 member societies.[1]
FAS publishes a newsletter 6 times a year, which is sent to its member societies, and holds in-person conventions as well as events online. The FAS is run by a council of elected volunteers.
A major benefit for local societies is to be able to arrange Public Liability Insurance from a policy which is shared between the members, greatly reducing the policy fee.
