Hampshire Astronomical Group welcome you!

Thank you for visiting our website

The Hampshire Astronomical Group operating from its Clanfield Observatory base on the borders of the villages of Horndean and Clanfield is reputed to be one of the best equipped amateur observatories in the UK.

Situated in the beautiful South Downs National Park we aim to bring the beauty of the night sky to the people of Hampshire and surrounding areas.

We hold many outreach events both at the observatory and further afield supported by our many volunteers who are keen to share their knowledge with you.

We hold monthly pre-booked open weekend evenings either 2 or 3 nights per month throughout the autumn to spring and in addition, during the summer, we hold solar observing sessions at the observatory. We also accommodate private group visits on selected evenings by prior arrangement – see our school and club visits page.

We run astronomy courses and the Duke of Edinburgh Award scheme at the observatory and offer outside speakers to organisations wanting a talk on some aspect of astronomy.

We have well nurtured relationships with organisations such as the South Downs Planetarium in Chichester, Winchester Science Centre, South Downs National Park and a number of colleges and Universities in Hampshire. We collaborate closely with the University of Portsmouth Physics Department and have good links with the Institute of Cosmology and Gravitation, also at the University of Portsmouth.

We hold monthly public lectures at the Clanfield Memorial Hall in South Lane (details below) often given by eminent speakers where members of the public are welcome to attend. No prior booking is necessary.

You can follow the activities of the Hampshire Astronomical Group by regularly visiting this website or follow us on our Facebook page.
