Scheduling the First Year of EUVE Guest Observer Targets

The Extreme Ultraviolet Explorer (EUVE) will be a Guest Observer mission after the completion of an all-sky survey in the first six months. The first Guest Observer pointing will take place at the end of January 1993. The EUVE Peer Review Panel met in mid-October 1992. NASA was scheduled to release the approved target list for the first year of GO pointings in mid-November 1992. The EUVE Science Operations Center then scheduled the targets consistent with the constraints on the satellite, which incidentally will change during the first year. The software used for scheduling consists of constraint and science plan generation programs written at the Center for EUV Astrophysics, UC Berkeley, and the SPIKE scheduling program written at the Space Telescope Science Institute, Johns Hopkins University. This poster will present the problems, solution, and performance of the software in scheduling the first year of EUVE Guest Observer pointings. This work has been supported by NASA contracts NAS5-30180 and NAS5-29298.
