SUBJECT: 19th Annual New Mexico Symposium -- 2nd Announcement Dark skies and remote sites have attracted world-class astronomical facilities to the Southwest and supported a wide range of research since the mid-1900s. Our achievements span areas in both science and technology including optical and radio interferometry, and research in solar physics, planetary science, star and galaxy formation, and the creation and evolution of our universe. To support the network of scientific research in the Southwest and encourage interdisciplinary discussions, the National Radio Astronomy Observatory (NRAO) is sponsoring the 19th Annual New Mexico Symposium on Friday, October 3, 2003, at the NRAO Array Operations Center in Socorro, NM. We invite astronomers, astrophysicists, and engineers working on astronomical instrumentation in New Mexico and surrounding states to attend the NM Symposium and to present a talk or poster (size is limited to 4' in length and 3' in width). We especially encourage students and postdocs. There is no charge for registration and NRAO will provide a symposium dinner free to officially registered meeting participants. The symposium will start at 9:00 A.M. and finish before 5:30 P.M. There will be four invited talks, each typically 30 minutes, including questions. We will also have time for roughly 15 oral presentations in a format with ten minutes presentation and five minutes discussion. We will also be able to accommodate at least 20 poster presentations. Our invited speakers for the 2003 NM Symposium are: Prof. Don Backer, University of California at Berkeley "Probing Microturbulence in the ISM via Pulsars" (15 min) Dr. Galen Gisler, Los Alamos National Laboratory "Three-dimensional simulations of the Chicxulub impact event at the Cretaceous-Tertiary (K-T) boundary" (30 min) Prof. Peter Hofner, New Mexico Tech "Massive Star Formation" (30 min) Prof. Neb Duric, University of New Mexico "The LOFAR Project: Impact on Regional Astronomy" (30 min) In the evening, Prof. Don Backer will present the Jansky Lecture, entitled ""Massive Black Holes, Gravitational Waves, and Pulsars". This free lecture will start at 8:00 P.M., at the Macey Center, on the New Mexico Tech campus, located next to the NRAO Array Operations Center. The general public is encouraged to attend. To register for the symposium, please visit the web site at http://www.aoc.nrao.edu/events/nmsymposium/2003/ and complete the on-line registration form. The deadline for registration is September 12, 2003. Further information about the meeting can be found at the web site. If you have any special requirements for your presentation, or questions about the symposium, feel free to contact Greg Taylor at . Since our mailing list of local astronomers is undoubtedly incomplete, we would appreciate your help in circulating this invitation to your colleagues and posting it on your bulletin board/s. We look forward to seeing you at the 2003 NM Symposium! Greg Taylor, Scientist National Radio Astronomy Observatory
