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 Great Equatorial Telescope, the largest of its kind in the UK, and seventh largest in the world.

We are an affiliated society of the British Astronomical Association and members of The Federation of Astronomical Societies.The Federation of Astronomical SocietiesBritish Astronomical Association

“Where else to start but at the Royal Observatory Greenwich.” This was quite an appropriate introduction to Malcolm’s talk at the 2nd meeting of the History of Astronomy group for this season. Malcolm has been a member of the Flamsteed Astronomy Society for over 10 years and served as Chairman for four (4) years. He […]

Talk on Radio Interferometry

On the 10th January 2018, a group of 23 Flamsteed members successfully negotiated the “get out of London” rush hour traffic to visit the Bayfordbury Observatory near Hertford, Hertfordshire. The Bayfordbury Observatory is the University of Hertfordshire’s teaching observatory for astronomy and astrophysics and is regarded as one of the finest astronomical teaching observatories in […]

It was a late Friday night many years ago that Andy Sawers stood in front of the National Portrait Gallery in London, awaiting the night bus to get home. He glanced around and saw a man standing in front of a telescope offering passers-by a view of the Galilean Moons for 50p. Andy took him […]

A few minutes before the Flamsteed’s first session with the Great Equatorial Telescope began, members were sat in the cafeteria guessing what our backup program might entail, for all we saw outside were clouds everywhere we looked. But then ROG’s astronomer, Brendan Owens, approached us with his usual beaming grin of optimism and told us […]

The exhibition called Observatory Life in the ‘astronomer’s apartments’ at the ROG has been under development for some time.  It tells the stories of two of the Astronomers Royal and their families who lived and worked at the Observatory.  The curator of the Royal Observatory, Dr Louise Devoy, generously agreed to show us round the […]

Barnard’s Loop in Orion A Flamsteed Astronomy Society workshop on Deep Sky Imaging at Mycenae House, Blackheath. Presented by Rupert Smith. Booking is required. Mycenae House is located in Mycenae Road just off Westcombe Park Road in Blackheath, SE3. It is close to the Blackheath Standard shops and buses. There is a café selling hot […]

Built in two phases by the London County Council for the supply of electricity to their tramways, construction of Greenwich Power Station began in 1902. Sited just half a mile from the Royal Observatory and exactly on the line of the Greenwich Meridian, the vibrations it created posed a serious threat to the effective operation […]

We will be running a Blackheath Observing session on Friday 9th March from 8pm until around 11pm. If the weather is poor on the Friday evening, the session will be moved to the following night, Saturday 10th March. We will have at least three scopes available at the session, but please feel free to come […]

Our Universe is, at the very least, 100 billion light years across. But where does this number come from? How can we measure the distance to even the nearest star when we’ve never visited? And, at a time when cosmologists reckon our Universe may be just one of many in a giant multiverse, will we […]

Martin and Jane have very kindly offered to run a viewing session from their observatory on Saturday 17th March (with a weather back-up date of Sunday 18th March). For the benefit of newer members, Martin’s observatory (a shed, but not as most of us know sheds) is very well equipped including a permanently mounted 14-inch […]
