WEA: HN,NL,PT,BR cloudy. 0913 Begin 0913-1008 *FD Ch08 extreme Tsys values (+-1800). 0913-1008 *SC Ch07,08 Tsys slightly high. 1335 New operator: T. Perreault 1335 Note: elevated system temperatures at SC and FD are most likely the result of RFI. 1832 End. Downtime Summary: Total downtime : 0 min Percentage downtime of observing: 0.0% Average downtime per hour : 0.0 min Total scheduled observing time (# Antennas): 5590 min (10) Notes: * = Entries where data was affected. % = Entries where data may have been affected. & = Entries where the site tech was called out. WEA = Weather entries. MF# = Maintenance form or major downtime category associated with a problem. %AD = The percentage of an antenna affected by a problem. AMD = Total antenna-minutes downtime for a problem. Tsys = System Temperature (TP/SP x Tcal/2) ACU = Antenna Control Unit FRM = Focus/Rotation Mount RFI = Radio Frequency Interference VME = Site control computer CB = Circuit Breaker vclock = Program that compares site clock time to a standard.
