Observing News -- Ron

We supported 21 projects in 34 observing sessions, including 2 VLB sessions. The telescope was also scheduled for 17.75 hrs of maintenance, 2.5 hrs for software tests, and 2.5 hrs for receiver checkouts. Lost time is only approximate this week and, if I have estimated correctly, will be something like 5 hrs or 3.3%. The causes of lost time were:

The LO1 errors were due to an undetermined limit to the length of a scan when Doppler tracking. The S-band diode problems happened when I was out of town and I don't know the problem's resolution. The X1/X2 subreflector problem should be treated as lost time but is not being logged as such; multiple observers have been affected. Operator logs show that the problem started and stopped without a cause reported.
