WIYN Project Progress Report (1Dec95) (from KPNO, NOAO Newsletter No. 44, December 1995) The WIYN Observatory has been routinely conducting science operations since mid-July 1995. Since the last NOAO Newsletter, the major milestones have been the release of MOS/Hydra for science operations and the installation of the baseline Instrument Adaptor Sub-system (IAS). MOS/Hydra was released to users in mid-August 1995. Since then, it has been in regular use with no significant operational problems. A 400 l/mm "blue" grating was added to the Bench Spectrograph grating complement in early September. Although a variety of minor issues are being cleaned up by the instrument team, the major uncompleted component is the all transmissive Red Camera, now scheduled to be released to users in March 1996. The IAS was installed in early September 1995. The IAS provides the hardware necessary for auto-guiding, closed-loop focus control, faster wavefront measurement, atmospheric dispersion correction, and comparison lamp illumination on the Nasmyth port not used by MOS/Hydra. It also provides a mechanical interface between instruments and the telescope. Currently, the WIYN Imager is mounted to the IAS. IAS components are being installed and commissioned incrementally. This process is expected to be completed in December 1995. Primary responsibility for managing on-site operations and improvement projects, as well as tracking telescope performance and taking appropriate action as necessary, has mostly been transfered from the Project staff to the Operations staff led by the WIYN Site Manager, Dave Sawyer. The WIYN Project lives on to accomplish three goals: (1) complete and commission the IAS; (2) close out the Project financial accounts; and (3) conduct an Operations Readiness Review. The main goal of the February 1996 Operations Readiness Review (ORR) is to provide an "as-built" snapshot of the WIYN Observatory. As with many projects, the WIYN Project started off with a set of the WIYN Scientific Advisory Committee (SAC) approved specifications, not all of which have been achieved by the real system. The ORR will develop a list of such unmet specifications for SAC review. The SAC will then decide whether the Observatory should try to meet those specifications in the future or accept them as they are, on a case-by-case basis. At the same time, issues such as the availability of spare parts, status of documentation, and level of training for operations and maintenance will also be reviewed. Such a review is necessary as part of the formal conclusion of the Project. Assuming that the SAC is satisfied with the ORR outcome, it is expected that the WIYN Project will be officially concluded during the March 1996, WIYN Board meeting in Tucson. Dave Silva
