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 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 members of The Federation of Astronomical Societies.The Federation of Astronomical Societies

Viewing the Sun through the 90mm Coronado

At our last Flamsteed committee meeting in May, Nick Phillips proposed that we set up a series of “members only” solar viewing events at the Royal Observatory Greenwich to take advantage of the equipment that we have available and to promote interest in solar observing amongst the Flamsteed membership. We’ve been running public sessions at […]

Solar Observing at the ROG

Report by Andy Sawers As the dawn chorus gave way to the sound of the school run, it still wasn’t at all obvious that we were going to have a good solar viewing day. The clouds weren’t great and the forecast wasn’t much better. Still, perhaps we’d get a couple of hours of showing and […]

Dome E - 26in Thompson

Report by Mike Meynell In truth, the Flamsteed don’t need much of an excuse to organise a trip to Herstmonceux, the second home of the Royal Greenwich Observatory. However, it was a bit of a surprise to find that it had been 6 years since our last visit, back in June 2008. It was the […]

Detached prominence - taken on Blackheath by Tej Dyal

Report by Rupert Smith In celebration of International SUNday we held a solar observing session at our regular Blackheath location on……Saturday! This was due to the better forecast offered on this day, which, despite some cloud from time to time, proved to be the right choice. There was a good turnout of scopes, which as […]

Our Guide Mohammed and a section of the LHC

Report by Mike Meynell There can’t be many astronomy societies that can boast of having arranged two trips to CERN in Geneva within a year! However, following on from the huge success of our first trip in September 2013, we decided to run a second trip in order to meet the obvious demand from Flamsteed […]

Ekaterinburg_view_of_2013_meteor_event

On the evening of Friday 15 February, asteroid 2012 DA14 made a close pass of Earth, at a distance of just 17,200 miles from the surface. This was the brightest ever “near-Earth object” (NEO) to be observed approaching Earth. Some news reports on the object can be found at the following links: http://www.bbc.co.uk/news/science-environment-21442863 http://www.nasa.gov/topics/solarsystem/features/asteroidflyby.html http://www.telegraph.co.uk/science/space/9873233/Asteroid-2012-DA14-brushes-by-Earth-as-it-happened.html […]

24th Jul, 2014

Amazing! I happened to be awake at 03:22 so I looked out of the window to watch the ISS pass over. The sky was misty with some light pollution so I couldn't see stars well. The ISS was very bright though (-2.9) and I could see a faint dot following it across the sky. I checked the NASA site and saw that it's docking with the Progress 56 cargo ship in the next hour or so, tweeted NASA to ask if that was what I'd seen and they replied most probably, yes! I had no idea I'd be able to see a cargo ship with the naked eye in a London sky!
