VERY LONG BASELINE ARRAY OBSERVING LOG -------------------------------------- Project: BM180B Observer: K. Marvel Project type: VLBA Obs filename: bm180bcrd.* Date/Day: 2003FEB23/054 Ants Used: SC HN NL FD LA PT KP OV BR MK =UT-Time===Comment===============================================MF#===%AD==AMD= Operator is Jim Ogle. *Freezing rain at HN. VCLOCK and gps delta check okay. 1200 Begin. 1306 Readbacks during the past hour all okay. 1402 Readbacks this past hour all okay. 1440 New operator: T. Perreault 1500 Readback checks for past hour all okay except for: NL drive 1 track 32 at 1439,1444,1452 UT 10917 1600 Readback checks for past hour all okay 1610-1643 &SC AZ#1 motor pulling between 50 to 90 amps. Have ACU 100 33 disabled AZ axis, motor is still pulling high amps. Stowed antenna, called out site tech to investigate. 1620-1626 *OV autostowed. Power glitch. Repointed. 10770 100 6 1640 &SC Pete on site. Repointed antenna so he can watch the currents. 1640 HN wea: overcast, fog, freezing mist. 1700 Readback checks for past hour all okay except for: NL drive 1 track 33 at 1625,1629,1634,1639,1643 10917 and at 1648,1657 UT 1800 Readback checks for past hour all okay except for: NL drive 1 track 33 at 1701,1706,1710,1715 UT 10917 NL drive 1 track 32 at 1725,1729,1738,1752,1757 UT 10917 1900 Readback checks for past hour all okay except for: NL drive 1 track 32 at 1805,1841,1856 UT 10917 1905-1954 *MK autostowed due to 55+ mph wind gust. Repointed. WEA 100 49 Antenna autostowed again before reaching source. Watched wind speeds as antenna was tipping, wind is accelerating as it goes over the dish, causing 55+ readings at the anemometers on the edge of the dish. Will leave antenna out until wind speed at the weather station dies off (currently around 35 mph). 2000 Readback checks for past hour all okay except for: NL drive 1 track 32 at 1901,1906,1916,1920,1926 10917 and at 1930,1936 UT NL drive 1 track 33 at 1956 UT 10917 2026 MK wea: clear, winds gusting NE 2100 Readback checks for past hour all okay except for: NL drive 1 track 33 at 2006,2011,2016,2021,2026 10917 and at 2036,2040,2045,2050 UT PT drive 2 tracks 14,16 at 2031 UT 2200 Readback checks for past hour all okay except for: NL drive 1 track 33 at 2123,2127 UT 10917 2259 OV wea: mostly clear, high thin clouds no precipitation 2300 Readback checks for past hour all okay except for: NL drive 1 track 32 at 2210,2215,2224,2228,2233, and at 2241,2249,2254,2258 UT BR drive 1 tracks 2,4,6,8,10,12,18,20,22,24,26,28,30 and 32 at 2258 UT 2341 SC observing ends 2354 Readback checks for past hour all okay except for: NL drive 1 track 32 at 2354 UT 2359 End.
