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 […]

Professor Philippa Browning

Solar flares are powerful “explosions” in the Sun’s atmosphere, the corona. They are caused by a rapid release of the energy stored in the strong magnetic field of the corona – the magnetic field lines break in a process known as magnetic reconnection. This heats the gas to temperatures of tens of millions of degrees […]
