VERY LONG BASELINE ARRAY OBSERVING LOG -------------------------------------- Project: TP023 Observer: G. Moellenbrock Project type: TEST Obs filename: tp023crd.* Date/Day: 2002AUG21/233 Ants Used: HN NL FD LA PT KP OV BR =UT-Time===Comment===============================================MF#===%AD==AMD= Operator is K. Jakischa. VCLOCK okay. 0859 Begin. 0859-1218 *HN has a problem with the rotation motors. 09393 100 199 Numerous unclearable faults keep subreflector from reaching position. Unusable, removed from observing. 0921-0922 *NL focus motion analysis fault. FRM 100 1 0937-0944 *KP focus motion analysis fault. Focus 09281 100 7 drifting from commanded position. 1037 %Readbacks okay except BR drive 1 tracks 15, 17-21, 30, and 32. 1055 Readbacks okay except OV drive 1 track 32. 1118-1119 *OV rotation drive fault. FRM 100 1 1124-1125 *OV rotation drive fault. FRM 100 1 1134-1135 *OV rotation drive fault. Rotation is occasionaly FRM 100 1 not locking at commanded position, recommanding fixes the problem. 1138-1139 *KP autostowed. Probably a power glitch. Repointed. COM 100 1 1140-1141 *OV rotation drive fault. FRM 100 1 1200-1201 *OV focus brake fault. FRM 100 1 1228-1229 *OV focus brake fault. FRM 100 1 1249 All readbacks okay. 1255-1257 *BR autostowed, 55+ mph wind gust. WEA 100 2 1307 PT Wea: Scattered low clouds, no precip. 1340-1356 *HN rotation motion analysis fault has 09393 100 16 returned. 1345 New Op. D. Medcalf. 1400-1508 *KP BBC7 appears to be getting no power. 09399 13 8 Site tech swapped BBC7 and 8. Both appear to be working now. 1404-1500 *HN rotation intermittently off. 09393 50 28 1500 All readbacks okay. 1514-1520 *BR autostowed. Reason unknown. WEAST 100 6 1534-1537 *BR autostowed again. Reason unknown. Site techs WEAST 100 3 contacted. 1546-2100 *KP BBC8 is now intermittently dead. 09399 13 40 1611-1614 *BR autostowed. 55+ mph wind stow reading, which is WEAST 100 3 false. 1640-1642 *BR autostowed. Site tech is working on the weather WEAST 100 2 station. Temporarily fixed. 1916-1932 *NL switched from drive 2 (full) to drive 1, but HWIII 100 16 tape is not recording. Site tech says tape is snarled around the capstan. Fixed, but tech says tape is about 125 ft. shorter now. 2033 Raining at NL. 2043 All readbacks okay. 2100 End. 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
