  1. The Astronomical Photographic Plate Center J.D. Cline1, M. W. Castelaz1, D. Clavier1, E. Griffin2, W. Osborn3 1Pisgah Astronomical Research Institute; 2Dominion Astrophysical Observatory;3Central Michigan University Not-for-profit public foundation www.pari.edu AAS 210th Meeting Abstract The Astronomical Photographic Plate Center (APPC) was established at the Pisgah Astronomical Research Institute (PARI) in 2004. The goal of the Center is to help preserve astronomical photographic data, first by serving as a repository for astronomical plate collections and eventually by digitizing these plates along with the log information material. The APPC is developing archiving methods compatible with the Harvard Smithsonian Center for Astrophysics scanning project for use by the National Virtual Observatory. In the three years of existence the Center has received over 38,000 plates. The largest collections are CTIO 4-m plates, CTIO and Warner and Swasey direct and objective prism Schmidt plates, and University of Michigan spectra. Preliminary catalogues of the plates are available on line. A small source of funding has been secured to support this work. Instructions will be available from the authors on the steps to follow for individuals or observatories wishing to archive their plates at the PARI APPC Center. • Storage Status • Plates in original envelopes and cabinets. • Temperature (18 C) and humidity (35%) controlled climate with backup power. • Essentially negligible chance of plate damage from natural disasters.

McGurk PARI Intern • Collections • CTIO plates: 4-m, Curtis Schmidt, and miscellaneous slit spectra from 1967 to 1998 • Warner and Swasey plates: direct and objective prism plates from 1944 to 1992 • University of Michigan plates: slit spectra from 1911 to 1973 • To contribute a collection: contact M. Castelaz, mcastelaz@pari.edu • Access • Preliminary catalogues of the plates are available on line: • Visits are encouraged. The Center has light tables, an iris photometer and a high resolution scanner • Requests for limited scanning of plates can be accommodated • Move towards compatibility with NVO, SIMBAD Spectra of Long Period Variables KPNO 4-m Plate Scanned 10 Oct 1949 slit spectrum of Mira.
