Observing News -- Ron

We supported 21 projects in 34 observing sessions, including 4 VLB sessions. The telescope was also scheduled for maintenance (16 hrs) and servo tests (2 hrs). Lost time was low -- 3.4 hrs, 2.2% -- and came from:

The safe-hold problems were very atypical and occurred within a few minutes of each other but haven't happened again since last weekend. One observer was informed of a later start time than that given to the operators and the receiver was ready before the observer was ready (i.e., it was our fault). The Earth/Grail/Astrid problem was also atypical.

Nothing to report. A very quiet week.
