The Flamsteed is an amateur astronomy society at the Royal Observatory and National Maritime Museum in Greenwich, London SE10. It has around 400 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 weather in the UK is notoriously difficult to predict. However, amateur astronomers can normally predict, years in advance, when we can expect poor weather and cloudy skies. Those conditions, almost without fail, occur on the day of major astronomical events! Fortunately, the evening of Tuesday 16th July 2019 bucked the trend. We were treated […]

View of the Lovell Telescope

On the 22nd June 2019, a group of Flamsteed members visited Jodrell Bank, part of the University of Manchester’s School of Physics and Astronomy and the home of the famous Lovell Radio Telescope. The site is also home of the Discovery Centre with its Planet and Space Pavilions which house interactive displays on radio telescopes […]

Eddie Yeadon delivers talk

“I have no idea what time is and I am not going to attempt an explanation.” This was the opening line for Eddie Yeadon’s talk for the fourth session of the History of Astronomy talks this season. Eddie has a PhD in physics from Manchester University and has had a long career largely focused on […]

Tony Sizer

Who actually invented the refracting telescope? This was the opening question which was put to the audience in our second session for the History of Astronomy group this season. The presenter was Tony Sizer, a former teacher of Chemistry, Science and Astronomy at Warwick School and Chigwell School and is currently one of the astronomers […]

Graham Dolan with Bobby Manoo

In our first talk for this season, we were taken back to the Royal Observatory during the period 1890 to 1895 to explore the work of five women who were employed as ‘Lady Computers’. Isabella Clemes, Alice Everett, Harriet Furniss, Edith Rix and Annie Russell all have very intriguing history relating to their work at […]

Martin and Jane have very kindly offered to run a viewing session from their observatory on Sunday 26th January. 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 SCT and a smaller refractor with CCD camera. Martin […]

This presentation details five major U.K. astronomical instruments of the nineteenth century. It will focus not just on the mechanics, but also on the people, known and not so well known, who designed, built and operated them. An appreciation of the engineering challenges encountered will be given along with the sometimes novel use of ‘crossover’ […]

Flamsteed viewing session with the Great Equatorial Telescope at the Royal Observatory Greenwich. Bookings are restricted to members only. Depending on numbers, we may be able to accommodate guests but we won’t know until much nearer the date. These Flamsteed sessions are free to members but places are limited and advance booking is essential. If […]

Dr Sarah Rugheimer

Talk details to follow. Dr Sarah Rugheimer is an astrophysicist working on how to detect life on an exoplanet. Her research interests are modelling the atmosphere and climate of extrasolar planets with a particular focus on atmospheric biosignatures in Earth-like planets as well as modelling early Earth conditions. Her focus has been on the star-planet […]

Martin and Jane have very kindly offered to run a viewing session from their observatory on Friday 21st February or Sunday 23rd February (weather permitting). 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 SCT and a […]
