These new support additions will be reflected in the RASM account. The current plan is to begin demonstration tracks at Santiago no early than May 22nd, 1995. Santiago's transition to full support commitment will be conducted in the same manner as it was performed at Wallops. After a number of demonstration passes have been successfully completed and the respective projects are completely satisfied with the data products and data delivery Santiago will then transition to full support commitment. By contractual agreement, Santiago's combined ASTRO-D and SOLAR-A coverage is not to exceed 3HRS total. This includes time allocated for Pre-cals, Post-cals, and reduced post-pass Playbacks. Support requests for ASTRO-D and SOLAR can only be honored if they are scheduled within Santiago's normal work hours of 1100z to 2300z, 7-days a week. Please contact me if you have any question or concerns regarding Solar-A support at Santiago. . Regards, Jose Valencia
