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

Setting up the telescopes on Blackheath

Well, you’ve got to love astronomy in the UK… don’t you?!… don’t you?!?!?!? A very frustrating couple of hours on Blackheath on Saturday evening. Nick and I had been discussing the weather for most of the day (in the absence of anything productive to do) and decided at 3pm that we would go ahead with […]

The Sky this Month: October 2014

by Mike Meynell Once again, we’ll take a look at what to see in the sky over the coming month. First of all, there will be an occultation of Saturn by the Moon, just after 5pm on Saturday 25 October. From Greenwich, Saturn starts to disappear behind the Moon at about 16:05 GMT (17:05 BST) […]

Bill Connor

The mainstay of our History Group programme has been the impressive knowledge and talent of our own members.  Bill’s talk added significantly to this growing tradition – Bill has special insights into the history of the telegraph network, the ‘Victorian Internet’, and he linked these to the development of Longitude determination and the ties to […]

Dr Ali Mozaffari

Dr Ali Mozaffari’s presentation on Testing Gravity in the Solar System was the opening event of the Flamsteed 2014-15 calendar – and it really raised the bar. But this being the Flamsteed Astronomy Society, many members leapt over that bar easily. In fact, Dr Mozaffari told us later how impressed he was by the quality […]

Sky this Month: September 2014

by Mike Meynell The autumn equinox is on September 23 – the point where the hours of night and day are equal, so we’re looking forward to the skies getting darker again. I’m going to cover the Moon and the planets and then move on to some of the other objects that you can view […]

Heather Couper and Dr Nigel Henbest

Heather Couper is an international broadcaster and writer on astronomy, space and science. Although a trained scientist, researching at Oxford, she has spent the last twenty years working entirely in the media. She has hosted two C4 series on British television, several TV programmes, and many radio shows – including the long-running series Seeing Stars […]

Looking at Cassiopeia with Flamsteed AS, from the 28 inch dome at the ROG, Greenwich

Flamsteed viewing session with the Great Equatorial Telescope at the Royal Observatory Greenwich. Bookings are restricted to members only. Depending on numbers, we may be able to accommodate guests but we won’t know until much nearer the date. These Flamsteed sessions are free to members but places are limited and advance booking is essential. If you […]

Blackheath Stargazing

We will be holding a Blackheath observing session on Friday 14th November (with a weather back up of Saturday 15th) from 8pm. The location for this event will be Blackheath. If you are unable to bring along your own telescope, don’t worry, there will be plenty on hand to show you the sights. Blackheath is […]

Flamsteed Astronomy Society shared International Space Station's video.

Facebook Picture

This extraordinary video clip was recorded at ESA - European Space Agency's Optical Ground Station (OGS) on Oct. 8 as the station illuminated the ISS with a 3.6-Watt 532-nm green laser, used for testing next-gen optical communication technologies. The video clearly shows the ISS bathed in green light as it is tracked by the OGS through the 4-minute pass at an altitude of about 420 km.

The video is a time lapse done at 7 shots per second with a reflex digital camera attached to the OGS secondary telescope.

The OGS is located at the Teide Observatory, Tenerife, Spain, which is operated by the Instituto de Astrofísica de Canarias.

The demonstration was conducted as part of ESA's #SpaceOptics SocialSpace event, 7-8 October.
