An astronomy society based in East Sussex sharing knowledge and news about space



Covid 19 has inevitably cause some disruption to our meetings but we have now made arrangements for us to get together in a Covid-Secure manner.  Details of meetings will be given here when they are confirmed.

Please note you can still also reach us via Facebook or Email.

Welcome to Seven Sisters Astronomical Society!

Welcome to Seven Sisters Astronomical Society (SSAS) – named after the famous Seven Sisters chalk cliffs and the glittering star cluster which shares their name.

We are a small group of amateur astronomers, space enthusiasts and friends with a common goal. We hold regular meetings in Willingdon, at the foot of the South Downs National Park, and observe at a handful of sites, mostly within the beautiful Seven Sisters Country Park. Our aim is to share our passion for space and to engage with the local community through public observing and outreach events.

SSAS is also a member of The Southern Area Group of Astronomical Societies- SAGAS. Click here for more information.


We are also members of Federation of Astronomical Societies (FAS). For more information follow this link.
