RAS Meetings

The RAS holds regular monthly meetings from October to May covering all aspects of astronomy and solid-earth geophysics, planetary sciences and solar-terrestrial physics. Usually, a pair of Specialist Discussion meetings for Fellows are followed by a more general Astronomy & Geophysics ('Ordinary') meeting, open to the public.

These regular meetings are held on the second Friday of the month, normally in the RAS and Geological Society lecture theatres (both at Burlington House, London). A map to these locations can be found here, and webcasts/podcasts of a number of meetings are available.

In April, the meeting is usually subsumed into the annual week-long RAS National Astronomy Meeting (NAM). 2013 and 2014 are exceptions, as NAM has been moved to July for both those years.

E-bulletins summarising imminent meetings can be subscribed to freely.

Specialist Discussion Meetings cover all branches of astrophysics and solid-earth geophysics (including, but not limited to, cosmology, astrobiology, astrochemistry, astroparticle physics, computational astrophysics; geophysical fluid dynamics, planetary sciences, solar-terrestrial physics). If you would like to give a talk at a Specialist Discussion Meeting, please contact the Meeting Organizer.

'Astronomy & Geophysics' (A&G) meetings, also called Ordinary Meetings, have more diverse programmes of talks, at a level accessible to a general audience of scientists (and advanced amateurs).  If you would like to give a talk at an A&G Meeting, please contact the Senior Secretary.

N.B.: A&G Meetings are open to all, with free admission. Registration charges are levied for the February BGA meeting,  and for non-Fellows attending any RAS Specialist Discussion Meeting. 

Radio intensity mapping as a new cosmological tool
Date: 9 May 2014
Time: 10:30


An RAS Specialist Discussion Meeting organised by Professor Ian Browne (University of Manchester)* and Dr Filipe Abdalla (UCL)
* Contact:


Mapping the integrated emission from redshifted neutral hydrogen is a new and completely independent way to measure baryon acoustic oscillations in the nearby universe. This technique can achieve powerful statistical constraints with relatively few data. New special purpose instruments are being proposed and will be built in the next few years.
The meeting will include discussion of the theory behind the method, description of new instruments and how the use of the compact core of SKA might revolutionize the subject.

Tea and coffee will be available from 10:00 and again after the meeting at 15:30.

Seismology from space: geodetic observations and early warning of earthquakes
Date: 9 May 2014
Time: 10:30


An RAS Specialist Discussion Meeting organised by Professor Peter Clarke (Newcastle)* and Professor Tim Wright (Leeds)


In recent years the availability of high-rate (1 Hz sampling or faster) GPS/GNSS data, often telemetered in near-real-time, has enabled the observation of strong ground motions, teleseismic waves, and "permanent" co-seismic deformation in the immediate aftermath of an earthquake.  Likewise, multiple-mission InSAR data have facilitated the observation of surface deformation at lower temporal but much higher spatial resolution.  This meeting will bring the UK geodesy and seismology communities together to examine the prospects for these techniques to enhance our understanding of the earthquake rupture process and provide early warning of earthquake mechanism and magnitude for the mitigation of earthquake-related hazards such as tsunamis.

Tea and coffee will be available from 10:00 and again after the meeting at 15:30.

RAS Ordinary Meeting
Date: 9 May 2014
Time: 16:00


Programme TBA.




  1. FEES: Admission to the Society's Monthly A&G (Ordinary) Meetings is open to all, at no charge. Admission to the Specialist Discussion Meetings is normally free to RAS members and £15 to non-members (£5 to students), collected on the door, while  GSL members may normally attend "G" meetings at no charge. Note that special rates apply for the February BGA meeting. RAS and GSL members should bring their membership cards, and students their student cards, as identification

  2. membership fees for those joining on the day.

  3. Coffee/registration for Specialist Discussion Meetings will commence a half-hour before the formal start time.

  4. Tea will be served before A&G meetings (15:30, at Geological Society Lecture Theatre, Burlington House) A drinks reception will follow A&G meetings, in the Burlington House apartments of Royal Astronomical Society.

  5. Copies of the detailed programme will be circulated, to those who have asked for them, approximately two weeks in advance of each meeting. Any member who does not already receive these details but wishes to do so should notify the Executive Secretary.

  6. Those wishing to make a contribution at a Specialist Discussion Meeting should contact the appropriate organizers.

  7. Contributions/Speakers for Monthly A&G (Ordinary) Meetings are most welcome, and should contact the Secretary or Executive Secretary.

  8. The Society welcomes suggestions for venues and topics for half- or one-day regional meetings; contact the Secretary or Executive Secretary.

  9. Detailed notes for organizers are available for reference.
