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

The solar eclipse!!! Honestly, it is there (behind the clouds!)

As I write this short report, I’m staring out at a beautiful sunny day. Hard to believe that only a few hours ago, we were completely clouded out when trying to view the largest partial solar eclipse visible from London since 1999! Ah well, that is the law of sod, is it not? The truth […]

Rupert presents the Solar System Imaging workshop

“Welcome to the first event at our new training centre!”… a tongue-in-cheek opening line from Rupert to introduce the first Flamsteed member’s event to be held at Mycenae House in Blackheath. In truth, we have been looking around for an additional venue to hold workshops for Flamsteed members, as, though the Royal Observatory is an […]

Louise Devoy

Looking around the galleries at the Royal Observatory Greenwich today, you’d be forgiven for not knowing about the work of the Magnetic and Meteorological departments in Greenwich. Understandably, the focus of the galleries is on the determination of time and the contribution of the Royal Observatory to positional astronomy in order to assist navigation. The […]

Moon with Earthshine above Blackheath

Our Blackheath observing session started early this month in order to catch the conjunction of Mars and Venus. Despite having to cancel on Friday we benefitted from mostly clear skies on Saturday. The conjunction did not disappoint and was clearly visible as was the distinctive orange colour of Mars. Above the two planets was the […]

Eddie Yeadon

We have come to expect Eddie’s talks to be well-researched, thorough, and challenging. This talk didn’t disappoint. As Eddie said in his introduction, this was not a talk about astronomy, it was about optics, and Eddie was on home ground – much of his professional career was in the field of optics. And 2015 has […]

Professor Richard Crowther is Chief Engineer at the UK Space Agency. He was Head of the Space technology Division at the Rutherford Appleton Laboratory until 2008 with primary research interests in manmade orbital debris planetary protection, and Near Earth Objects (NEOs – asteroids and comets that pass close to earth). He is currently head of […]

DSCN7796-Web

We are pleased to be running a short workshop to give an introduction to the basics of astrophotography. In this 90 minute session, we will introduce the sort of equipment that you might need for basic astrophotography, camera settings for taking the best astro images and the types of image that you can take. We […]

Royal Astronomical Society

Brian Blake has very kindly arranged for us to visit the Library of the Royal Astronomical Society (RAS). The visit will start at 2pm on Friday April 24th 2015 and last 1 to 2 hours. The Librarian, Dr Sian Prosser, will give us an introductory talk and will set out some rare treasures including works […]

Three crew members representing the United States and Russia are on their way to the International Space Station after launching from the Baikonur Cosmodrome in Kazakhstan at 3:42 p.m. EDT Friday (1:42 a.m., March 28 in Baikonur). from NASA

Millions of images of celestial objects, including asteroids, observed by NASA’s Near-Earth Object Wide-field Survey Explorer (NEOWISE) spacecraft now are available online to the public. The data was collected following the restart of the asteroid-seeking spacecraft in December 2013 after a lengthy hibernation. from NASA

Using observations from NASA’s Hubble Space Telescope and Chandra X-ray Observatory, astronomers have found that dark matter does not slow down when colliding with itself, meaning it interacts with itself less than previously thought. Researchers say this finding narrows down the options for what this mysterious substance might be. from NASA

NASA Wednesday announced more details in its plan for its Asteroid Redirect Mission (ARM), which in the mid-2020s will test a number of new capabilities needed for future human expeditions to deep space, including to Mars. NASA also announced it has increased the detection of near-Earth Asteroids by 65 percent since launching its asteroid initiative […]

NASA will host a media teleconference at 2:30 p.m. EDT today to discuss the selection of an Asteroid Redirect Mission concept and other advances supporting the agency’s journey to Mars. from NASA

A total eclipse of the sun on Friday thrilled skywatchers across Europe, Africa and Asia where it was visible, but nowhere was the view as perfect as in the air aboard a chartered jet soaring over the top of the world.

Look up! Luna's looking so pretty in the sky, with Venus further away than yesterday. Good time to go out and capture the earthshine on the moon! Exp time between 1/2 sec to 3 sec

Here how it looked yesterday. Have a go!

Flamsteed Astronomy Society updated their status.

Our Blackheath observing event is CONFIRMED ON for tonight.

This will be a short observing session up until 9pm, as it’s been a long day with our solar eclipse event this morning! (a report of this event can be found on the website: http://flamsteed.info/2015/03/solar-eclipse-viewing-event/ ).

Jupiter is still well placed in the sky, and we hope to observe Venus early in the evening as well. Venus is about 81% illuminated at the moment, so we should just about be able to detect the phase. Orion and the Pleiades will be nice early evening targets as well.

So we look forward to seeing as many of you as possible. Bring a scope if you can, if not just turn up for a look. There will be other scopes available.

Blackheath is quite exposed, so please remember to wrap up warm.

The plan is to meet on Blackheath, just north of Talbot Place at 7.00pm. Talbot Place is a right turn off Goffers Road as you head towards Shooters Hill Road or the first left after the Tea Hut. Talbot Place is a cul-de-sac, where free parking is available from 6.30pm. A map of the site can be found on the Flamsteed website - http://flamsteed.info/observing/stargazing-events/blackheath-stargazing/ .

Solar Eclipse....How exciting, this is my take on it. We had a very quick glimpse for a few minutes or maybe just a minute. Lots of people on the Pier and on the beach... I used the 6 stop filter so managed to capture some movement in the cloud, a magical moment in time. :)

We have two observing events planned for tomorrow (Friday 20 March).

Tomorrow morning, we are running a solar viewing event at the Royal Observatory Greenwich to attempt to view the partial solar eclipse. The eclipse starts at 08:25, with the maximum (85% coverage) at 09:31 and the eclipse ending at 10:41. We’ve had an incredible response from Flamsteed members, with 31 people volunteering to help out. Flamsteed members will be providing 10 telescopes, adapted for safe solar viewing, which will be situated in the area in front of the General Wolfe Statue in Greenwich Park. In addition, the solar telescopes that the Flamsteed have donated to the Royal Observatory will be in use, with Flamsteed volunteers helping to operate these scopes. Solar glasses will also be available.

If you have not volunteered to help out at the event, you are still very welcome to attend as a member of the public. There is no charge. We have more than enough equipment, however, so please don’t bring any extra equipment along.

Tomorrow evening, we will be running a Blackheath Observing event from 7pm. The forecast for later in the day is more positive, so there is every possibility that we will be running this event as planned. Jupiter is still well placed, and we hope to observe Venus early in the evening as well. Venus is about 81% illuminated at the moment, so we should just about be able to detect the phase. Orion and the Pleiades will be nice early evening targets as well.

As usual, the plan is to meet on Blackheath, just north of Talbot Place at 7.00pm. Talbot Place is a right turn off Goffers Road as you head towards Shooters Hill Road or the first left after the Tea Hut. Talbot Place is a cul-de-sac, where free parking is available from 6.30pm. Blackheath is quite exposed, so please remember to wrap up warm. A map of the site can be found on the Flamsteed website - http://flamsteed.info/observing/stargazing-events/blackheath-stargazing/ .

We will send our usual “go/no-go” message at some point on Friday afternoon, when we are certain about the weather conditions.

We look forward to seeing you at one or both of these events.
