To join the Flamsteed Astronomy Society, click on this link.

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 Federation of Astronomical SocietiesBritish Astronomical Association

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 […]

Astronomical Events for 2019 by Malcolm Porter Sources– Extracts from the BAA 2018 Handbook, The BAA 2019 Handbook, Astronomy Now 2019 Yearbook, and Philip’s Stargazing 2019 Month by Month Guide. This list has been built around the idea of the Astro Highlights being largely visible to the naked eye, through binoculars or through a small […]

On 8th November Martin and Jane made welcome a small group of star-starved Londoners and gave us a dazzling guided tour of the star-spangled sky over Romney Marsh. Martin trained his Meade 14” SCT (Schmitt Cassegrain Telescope) on a fascinating variety of deep sky objects and planets. With such a powerful telescope we were able […]

On Saturday 12th May, a group of 20 Flamsteed members ventured out to the University of Cambridge’s Mullard Radio Astronomy Observatory. Located at Lord’s Bridge near the small village of Barton in Cambridgeshire, the site was once a railway station on the Varsity Line that ran between Oxford and Cambridge. That, in fact, is where […]

Atomic Clock Calibrated by Use of Ephemeris Time

Units for measuring time have been realised through the rotation of the Earth – the day. As the precision of clocks improved, it was found that the length of the day was variable. An astronomical solution was to use solar system orbits instead of Earth rotation to define the unit. This resulted in the adoption […]

We will be running a Blackheath Observing session on Friday 26th April (main night) or Saturday 27th April (weather back-up night, if conditions on Friday are poor) from 9.30pm until around 11.30pm. As with all observing events, we will only go ahead if weather conditions allow, and a “go/no-go” decision will be made on the […]

During the summer months, we run several public solar viewing sessions at the Royal Observatory Greenwich. These sessions prove to be extremely popular, with many thousands of visitors attending the solar viewing events over the course of the summer. All of these sessions are run by Flamsteed volunteers, and they wouldn’t take place without the […]
