John Flamsteed

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 (NMM) in Greenwich, London SE10.  It is named after the first Astronomer Royal, John Flamsteed.

It has around 350 members who represent the full range of interests and experience in astronomy.  Beginners are very welcome.  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 NMM, or in the Peter Harrison Planetarium at the Royal Observatory Greenwich (ROG).  We feel it a privilege to be able to hold our meetings on a site of such astronomical significance, and to have access to the ROG professional staff and other eminent guest speakers.  As well as the history of the subject, lectures are arranged  on all aspects of astronomy including cosmology and space flight.  Information about our previous meetings and visits can be found in the Meeting Reports section of this website.

Some members of the Society work as volunteers at the ROG, as observing assistants and tour guides.  One of the Society’s objectives is to help the ROG by making donations of equipment to enhance the educational work.  Three Hydrogen-alpha solar telescopes have been donated and have enabled visitors to the Observatory to see prominences and sunspots.  Members participated very successfully with the solar telescopes at ROG events for the public to watch the 2004 Transit of Venus, the partial solar eclipses in 20052006, & 2008 and the 2012 Transit of Venus.

We have access to the ROG Peter Harrison Planetarium, the most modern in Europe, and we arrange briefings about the night sky presented by the ROG astronomers.  Once or twice a year we stage telescope workshops at the ROG to help beginners choose and use starter telescopes, or to assist more experienced observers with planning an upgrade or using advanced techniques. We also run an introduction to astrophotography workshop, to help people make a start in astrophotography using basic equipment.

The Society regularly holds observing evenings using members’ own telescopes. Observing sessions are held on Blackheath SE3, at Cudham in Kent, and at Romney where a member has a permanently-mounted 14-inch SCT telescope.  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.

Eminent speakers at the Society have included Prof Colin Pillinger, Sir Arnold Wolfendale (14th Astronomer Royal), Prof John Brown (Astronomer Royal for Scotland), Dr Chris Lintott (Co-Presenter of the BBC Sky at Night), Prof Jim Al-Khalili, Heather Couper, Pete Lawrence (BBC Sky at Night) and Prof Dame Jocelyn Bell-Burnell.

Excursions and visits are arranged during the Summer, along with some social activities. In the past we have visited CERN in Geneva, HerstmonceuxJodrell BankRutherford Appleton Labs near Didcot, the Herschel Museum in Bath, the Orwell Park Observatory near Ipswich, and the Paris Observatory.

Membership of the Flamsteed includes membership of Royal Museums Greenwich (RMG). Membership of RMG provides you with a number of benefits in addition to those offered by the Flamsteed:
