VERY LONG BASELINE ARRAY OBSERVING LOG -------------------------------------- Project: BC132A Observer: Carilli, C. Project type: VLBA Obs filename: bc132acrd.* Date/Day: 2003APR16/106 Ants Used: SC HN NL FD LA PT KP OV BR MK Y GB =UT-Time===Comment===============================================MF#===%AD==AMD= Operator is Cyrus M Reed. VCLOCK and GPS DELTA OK. UT1-UTC OK (-0.35). WEA: SC,HN,NL,FD Cloud cover unknown (night). WEA: LA Partly cloudy, wet. WEA: PT Partly cloudy. WEA: KP,OV,BR Clear skies. WEA: MK Partly cloudy. 0200 Begin observing. All antennas on source. MK starts late at 0259UT (scheduled). 0200-0215 *Y does not appear to be observing. HUERR 100 15 Resent files to Y, and it started up - possibly coincidence, or perhaps the files weren't sent correctly. The antenna file was at the site when I checked, before resending the files. 0251-0257 *Y MSG: Observing system idle. This would not seem SW 100 6 to be correct, judging from the file. Rebooted site computer - came back observing. VLA operator hasn't seen anything unusual. 0304 MK readbacks OK. 0309 MK readbacks OK. 0309-0342 *NL EL #1 armature/electronics CB fault. ACU 100 33 Antenna has stopped moving in EL. Site tech called. 0329 NL tech on site. 0342 NL EL fuses replaced; antenna pointed. 0401 *BR bad readbacks: Drive 1, Tracks 03,05-09, BR (cont.): 15,17,19,21,30-33. *Y bad readback: Drive 1, Track 33.

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 = TP/SP x Tcal/2
