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 an affiliated society of the British Astronomical Association and members of The Federation of Astronomical Societies.The Federation of Astronomical SocietiesBritish Astronomical Association

Andy on the Flamsteed stall

Once again, the Flamsteed were delighted to be invited to participate in the Shrewsbury Park Summer Festival this year, set on top of Shooters Hill with fabulous views over London, Kent and Essex. In fine weather this is a perfect spot for astronomy, and our plan was to provide several solar telescopes for people to […]

Matt Taylor at the Flamsteed

For the final lecture of our 2015/16 season, Flamsteed members were given a real treat when Dr Matt Taylor from ESA came to talk about the Rosetta mission. Matt is the Project Scientist for this mission, working as the interface between the scientists responsible for the experiments on the mission and the ESA mission operation […]

The Flamsteed Radio Astronomy Group continues to make good progress. At the last meeting on Tuesday 7 June 2016, the group had 5 VLF (Very Low Frequency) receivers up and running in an attempt to compare performance. A Very Low Frequency (VLF) Receiver is designed to record Sudden Ionospheric Disturbance (SIDs) induced by solar flares. […]

Jupiter from Blackheath 14 May 2016

Our observing session on Blackheath this Saturday was again in danger of being cancelled due to bad weather. At least that’s what each of the 6 forecasting sites I looked at said. However one did say it was going to be patchy cloud instead of a thick blanket and it also seemed to be agreeing […]

Graham Dolan

The ROG was preparing for new galleries called ‘Observatory Lives’ focusing on two of the Astronomers Royal, Maskelyne and Airy, and their families who lived at the Observatory in Flamsteed House. By way of contrast, Graham Dolan spoke to us about some of the nineteenth century assistants at the Observatory, people who did the work […]

‘Astrobiology’ is a brand new field of science, encompassing research into the origins and limits of life on our own planet, and where life might exist beyond the Earth. But what actually is ‘life’ and how did it emerge on our own world? What are the most extreme conditions terrestrial life can tolerate? And what […]

Solar Observing at the Royal Observatory Greenwich – CONFIRMED ON

The Perseids Meteor Watch session in Cudham is CONFIRMED ON for tonight (Thursday 11th August).

We are taking a bit of a risk with the weather, as there is a fair amount of cloud about. Some forecasts are suggesting cloud cover for most of the night, whereas others suggest clearing skies from 11pm. Given that this is the optimum night for observations, with the Moon setting just after midnight, and the potential of an “outburst” of meteors (peak rates of almost twice the usual rate – ZHR of 210 is predicted), we think it’s worth the risk of running the event.

Location details can be found on the Flamsteed website:
http://flamsteed.info/event/perseids-meteor-watch-3/

We aim to start the session at around 10pm and continue for as long as people are happy to stay.

Attendees should use the car park in the Blacksmiths Arms, providing there is space. If you do use the pub car park, you are encouraged to pop into the pub for a drink prior to the event, as a thank you for using their facilities. The address is Cudham Lane South, Cudham, Kent, TN14 7QB.

Please note that the recreation ground car park is normally locked at about 11pm, so if you park in this area, you may find that you are stuck until the morning! Use the pub car park if you can.

We'd recommend bringing a deck chair or similar reclining chair, or a blanket to lie on. Feel free to bring cameras, telescopes or any other equipment. Also, make sure you bring some warm clothing. The area we have chosen for viewing is relatively dark and you are therefore advised to bring a torch (red light, if possible).
