VERY LONG BASELINE ARRAY OBSERVING LOG -------------------------------------- Project: BS120C Observer: S.Spangler Project type: VLBA Obs filename: bs120ccrd.* Date/Day: 2003JAN23/023 Ants Used: SC HN NL FD LA PT KP OV BR MK =UT-Time===Comment===============================================MF#===%AD==AMD= On duty Operator: Peggy Perley 2031-2400 %BR High tsys (3x nominal) due to poor weather WEA 100 209 2031 %HN some snow in the dish 2052 %KP Focus motion analsis fault. FRM 2101 %KP High Tsys on CHs 1 and 2. 2101 %HN Rotation position error > 0.1 degree. 2111-2113 *KP Focus motion anlysis fault. FRM 100 2 2117-2119 *OV Rotation drive fault. FRM 100 2 2121-2125 *KP Focus motion analysis fault. FRM 100 4 2123 KP WEA: Broken high clouds, none, dry. 2151-2152 *KP Focus motion analysis fault. FRM 100 1 2153-2154 *HN Rotation motion analysis fault. FRM 100 1 2201-2203 *HN Rotation position error. FRM 100 2 2203-2219 *NL Site tech needs to warm up the 7mm. CRYO 100 16 2245 New Op. D. Medcalf. 2355-2356 *Had to reboot MK site computer to restore rcmd SW 100 1 function (needed to swap drives). 0000 Date is 2003JAN24/024. OV wea: cloudy, dry. 0003-0005 *KP focus way off. FRM 100 2 0013-0017 *KP focus very confused about where it's supposed FRM 100 4 to be. Did a master reset. 0017 BR wea: broken low clouds. 0022 MK wea: clear. 0030-0645 *KP is having a focus motion analysis fault every- FRM 33 123 time it tries to go to 6cm. I will try to correct the small error when possible. Setting downtime to 1/3 for times where error is not caught or fixed. 0045-0047 *HN rotation off by about 4 degrees. FRM 100 2 0437 All readbacks okay. 0639 All readbacks okay. 0645 New Operators: J. Ogle and D. Pierce. 0645-0830 *Closed previous KP focus motion analysis fault FRM 6 6 entry, with two operators watching things it should be easier to catch problems and minimize downtime. 0650-0651 *HN Rotation position error. FRM 100 1 0700-0702 *KP focus motion analysis fault, had trouble FRM 100 2 getting it to go onto position. 0700-0703 *HN EL#2 armature overcurrent fault. Put antenna ACU 100 3 in standby then repointed. 0710-0713 *HN Rotation position error. FRM 100 3 0730-0733 *HN Rotation position error. FRM 100 3 0750-0754 *HN Rotation position error. FRM 100 4 0800-0803 *HN Rotation position error. FRM 100 3 0820-0823 *HN Rotation position error. FRM 100 3 0830 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
