VERY LONG BASELINE ARRAY OBSERVING LOG -------------------------------------- Project: BM269A Observer: Moscadelli, L. Project type: VLBA Obs filename: bm269acrd.* Date/Day: 2008JAN28/028 Ants Scheduled: SC HN NL FD LA PT KP OV BR MK =UT-Time===Comment===============================================MF#===%AD==AMD= Operator is Anthony Sowinski. UT1-UTC -0.29, gps delta and vclock okay. Recent rain at LA and KP. Windy at FD and PT. 1343 Begin. 1400-1856 %PT system temps are very high. There might be snow WEA 100 296 or ice on the dish. OV temps are also high. 1442 New operator is Heidi Gerhardt 1454-1458 *PT FIFO errors, clearable. FMTR 100 4 1542-1543 *PT FIFO errors, clearable. FMTR 100 1 1616 New operator: T. Perreault 1647 PT update: dish & feed have a covering of slush and water - system temperatures have come down since the start of the file. 1724-1726 *PT Formatter errors FMTR 100 2 Header control module 2 error HC2 FIFO error Backplane 1PPS marker detected FIFO 3 1PPS detected FIFO 2 1PPS detected FIFO 1 1PPS detected Cleared errors 1755-1758 *OV AZ1 armature over current error ACU 100 3 Cleared error 1822-1823 *PT Formatter errors FMTR 100 1 Header control module 2 error HC2 FIFO error Backplane 1PPS marker detected FIFO 3 1PPS detected FIFO 2 1PPS detected FIFO 1 1PPS detected Cleared errors 1856 PT update: system temperatures are within normal range. 1940-1941 *PT Formatter errors FMTR 100 1 Header control module 2 error HC2 FIFO error Backplane 1PPS marker detected FIFO 3 1PPS detected FIFO 2 1PPS detected FIFO 1 1PPS detected Cleared errors 2018-2022 *PT Formatter errors FMTR 100 4 Header control module 2 error HC2 FIFO error FIFO 0 1PPS detected Cleared errors 2059 KP wea: broken low clouds, no precipitation 2148-2150 *PT Formatter errors FMTR 100 2 Header control module 2 error HC2 FIFO error Backplane 1PPS detected FIFO 3 1PPS detected FIFO 2 1PPS detected FIFO 1 1PPS detected Cleared errors 2254 New Operator: Paul Padilla 2311 %OV windy 2330-2333 *OV autostowed in wind gust. WEA 100 3 2334-2342 *OV autostowed in wind gust again. Going to leave WEA 100 8 it out until the winds die down. 2342 End. Downtime Summary: Total downtime : 325 min Percentage downtime of observing: 5.4% Average downtime per hour : 3.3 min Total scheduled observing time (# Antennas): 5990 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.
