Flamsteed Astronomy Society

The Flamsteed is an amateur astronomy society at the Royal Observatory and National Maritime Museum in Greenwich, London SE10. It has around 350 members who represent the full range of interests and experience in astronomy. Many are beginners. It is named after the first Astronomer Royal, John Flamsteed. The Society was founded in 1999, and is part of the membership organisation of Royal Museums Greenwich. Our lecture meetings are held once a month between September/October and May/June, usually on a Monday evening, in the lecture theatre of the National Maritime Museum, or in the Peter Harrison Planetarium at the Royal Observatory Greenwich (ROG). The Society regularly holds observing evenings using members’ own telescopes. In addition the Society stages viewing sessions with the ROG’s 28-inch Great Equatorial refractor, the largest of its kind in the UK, and seventh largest in the world. We are members of The Federation of Astronomical Societies.
