66 -- ATMOSPHERIC SEEING MONITOR SOL RC970171 DUE 120197 POC Andrew Flach, Contracts Manager, 520-318-8537 WEB: General Information about the Gemini 8m Telescopes Project, http://www.gemini.edu. E-MAIL: Contact the Contracts Manager via email., aflach@gemini.edu. The Association of Universities for Research in Astronomy, Inc. (AURA) is seeking qualified vendors to provide a seeing monitor for use at the Gemini Observatory, Cerro Pachon, Chile. The seeing monitor will consist of a small robotic 14-16 inch aperture telescope, associated mount, drive/tracking electronics, fully retractable enclosure, support computer, and integral Differential Image Motion Monitor (DIMM). Over the course of a night the system must be able to automatically acquire stars and output to a remote computer measurements of the local seeing, in the form of the Fried parameter (r0) or similar seeing diagnostic. Automatic measurements of other atmospheric properties including the Greenwood frequency and nightly extinction coefficients are desirable goals of the system, but are not required as part of the baseline design. The Gemini 8m Telescopes Project is an international collaboration to build two 8 meter telescopes, one to be located on Mauna Kea in Hawaii, the other to be located on Cerro Pachon in Chile. The Gemini project partners include the USA, United Kingdom, Canada, Argentina, Brazil and Chile. The Gemini project is operated by the Association of Universities for Research in Astronomy, Inc. (AURA) under contract to the National Science Foundation. Companies who are interested in receiving the Request for Proposal for this procurement should send a letter of interest by 1 December, 1997, to the following address: Gemini 8m Telescopes Project, 950 North Cherry Avenue, PO Box 26732, Tucson, Arizona 85719-6732 (PO Box) 85719 (Street address), Attn: Contracts Manager, Request for Proposal No. RC970171.
