VERY LONG BASELINE ARRAY OBSERVING LOG -------------------------------------- Project: BK134C Observer: Kovalev, Y.Y. Project type: VLBA Obs filename: bk134ccrd.* Date/Day: 2007APR30/120 Ants Scheduled: SC HN NL FD LA PT KP OV BR MK =UT-Time===Comment===============================================MF#===%AD==AMD= Operator is Alan Kerr Weather: SC, HN overcast, raining at times. GPS (NL 8.9), UT1-UTC (-0.11), vclock OK. 0647 Begin at all sites. 0701-0704 *KP,SC,HN needed a Master_Clear FRM 300 9 0824-0832 *SC multiple Rotation errors during 4cm. FRM 100 8 1220-1224 PT out of point. repointed. OTHER 100 4 1226 HN precipitation starting. 1235-1239 *FD wind autostow (gust of 1.6???) repointed. WEA 100 4 1345-1347 *SC out of point, repointed. power glitch? COM 100 2 1359 New operator is Betty Ragan. 1418 BR reports scattered high clouds, dry dish. 1426-1427 *NL needed master clear due to focus motion FRM 100 1 analysis fault. 1505 OV reports clear, dry weather. 1520 KP reports clear, dry weather. 1534-1536 *SC hot AZ#1 and EL#1 armature/electronics CB COM 100 2 errors and left point mode. Commercial power came back at about this time after being on generator. Repointed. 1600-1601 *KP needed master clear due to rotation drive fault. FRM 100 1 1701-1718 *NL out of point so the site techs can do some work OTHER 100 17 on it. 1908 MK reports clear weather. 1937-1939 *PT autostowed. Probably a power glitch. COM 100 2 1936 %NL frequently showing an error flag for the ellipsoid. THis is probably not affecting data, but it's hard to say for sure. 2132 Operator is Anthony Sowinski. 2152 KP reports scattered low couds, no precip. 2229-2231 *PT Auto-stow; power glitch? ACU 100 2 2241 %SC Raining. 2319 OV reports cloudy, no precip. 0000 Date is 2007MAY01/121. 0539 New operator is Jim Ogle. 0619 End at SC. 0632-0633 *FD rotation position error. FRM 100 1 0632-0634 *BR rotation position error. FRM 100 2 0648 End. Downtime Summary: Total downtime : 55 min Percentage downtime of observing: 0.4% Average downtime per hour : 0.2 min Total scheduled observing time (# Antennas): 14410 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.
