01.01.30 The First Announcement for the 2001 Michelson Interferometry Summer School has been issued. The Summer School will be held in the week of 21-25 May 2001 on the Campus of Lowell Observatory. It will emphasize aspects of data reduction by example, with contributions from NPOI, FLUOR, PTI, and aperture masking the Keck telescopes. The application deadline is March 9, 2001.
01.01.30 The European Space Agency (ESA) offers Postdoctoral Research Fellowships that are available to nationals of ESA member states (Austria, Belgium, Denmark, France, Finland, Germany, Great Britain, Ireland, Italy, the Netherlands, Norway, Spain, Sweden, Switzerland; Canada is also included as a Cooperating State). More information is available by contacting ESA at
01.01.30 Beginning 1 October 2000, and for a duration of 4 years, three research groups located in Paris area have been selected by the European Commission to become a Marie Curie Training Site. These are the Département de recherche spatiale at Observatoire de Paris (DESPA), the Institut d'Astrophysique Spatiale (IAS) at Université Paris 11, and the Département d'Optique Théorique et Appliquée (DOTA) at ONERA. They will accept young researchers during the course of their PhD preparation for a period of 6 to 12 months, in order for these PhD students to carry their activity in one of the groups on subjects related to Astronomical optical interferometry and related science. Travel and local expenses of the PhD students are covered by the Program, as well as a contribution to the research carried during the stay. In the program a total of 96 months of stays is available for the period October 2000-September 2004. Applicants must be 35 years old or less, be a national of an European Union member state or Associated State, and must not undertake the Fellowship in the country of their nationality or recent center of activity (exceptions to the Requirements are possible in certain cases). For more information see the Announcement at the DESPA Web Site.
01.01.29 Photographs of the I2T, GI2T, and SOIR interferometers at the Observatoire de la Cote d'Azur are available. These include close-up photographs of the instrumentation in REGAIN, the new beam combiner of the GI2T. Included are several panoramas and numerous stereo pairs. [The stereo pairs may be viewed by selecting suitable pairs of nearly identical photos, reducing their size and arranging them side-by-side. Cross-eyed viewing works well in the cases I've tried.] See Photos 1, Photos 2, Photos 3, Photos 4, and Photos 5 (the 5th set contains photographs of SOIR and the old optical table of the GI2T.)
01.01.17 OLBIN is moving to a new address, Please now update your links. The move is substantially complete, but there will likely be some inconveniences. Please email lawsonexternal image arobas.jpghuey.jpl.nasa. gov if you spot anything I've missed. The news will continue at that site. Web access to huey will be discontinued in the near future.
01.01.17 The web-based Proceedings of the Leiden Interferometry Summer School (18-22 September 2000) containing viewgraphs from the Summer School, are now available courtesy of Isabelle Percheron.
01.01.16 Quicktime movies of simulated Hyper-telescopes are available courtesy of Mike Kaplan (Boeing-SVS). The movies include simulations of Antoine Labeyrie's free-flying array (18 MB) and Francois Roddier's rotational array (17 MB). A Quicktime player is required to view the movies.
01.01.13 The Proceedings of the NSF-sponsored workshop on Imaging with Ground-Based Interferometers (PDF 169kB), held in Socorro last June, is now available courtesy of Hal McAlister.
01.01.04 You can now Search OLBIN to rapidly find items of interest in these pages (courtesy of Melanie Swain).
01.01.03 The CDROM Origins Interferometry, containing PDF versions of the TPF Book (JPL Pub. 99-3), the SIM Book (JPL Pub. 400-811), and Principles of Long Baseline Stellar Interferometry(JPL Pub. 00-009) is now available. To obtain a free copy please email Debi Fambro at JPL,, including as subject "CDROM Request" and your name and address in the body of the message. Copies will also be available for distribution at the AAS Meeting in San Diego, January 7-11, 2001.
