VERY LONG BASELINE ARRAY OBSERVING LOG -------------------------------------- Project: BT085S Observer: Taylor, G. Project type: VLBA Obs filename: bt085scrd.* Date/Day: 2006AUG12/224 Ants Scheduled: SC HN NL FD LA PT KP OV BR MK =UT-Time===Comment===============================================MF#===%AD==AMD= Operator is Sonja Mendoza. Vclock, GPS delta and UT1-UTC time checks all okay. SC,HN,NL,FD,LA,PT,KP WEA: Partly cloudy, fair cumulus clouds, dry. BR WEA: Clear skies, dry. 1728 Begin observation with all antennas. MK joins later. 1728-1733 *OV BBC7 has low total power, switched power 18778 12 5 is near zero. 1728 &OV Site tech has been contacted and is enroute to site to investigate BBC problem. 1733-1735 *OV Site tech reseated BBC7. 18778 100 2 1744-1756 *PT autostowed; probable power glitch, repointed. COM 100 12 1809 OV WEA: Site tech reports clear skies, dry. 1900 MK joins the observation. 1900 MK WEA: Clear skies, dry. 1912 %FD WEA: Approaching t-storms, wind gusts > 35 mph. 1921-1948 *FD autostowed, probably due to a power glitch COM 100 27 brought on by the weather. 1926 FD Site computer rebooted itself, no doubt due to poor power. Constant glitches, will repoint when situation improves. 1927 %FD WEA: Precipitation starting. 1945 PT WEA: Increasing clouds, overcast skies. 1945 LA,KP WEA: Increasing clouds. 1958 %PT WEA: Precipitation starting. 2018-2022 *FD autostowed, probable power glitch. COM 100 4 2028-2036 *FD autostowed, probable power glitch. COM 100 8 2050-2053 *PT autostowed, probable power glitch. COM 100 3 2120-2123 *KP autostowed, probable power glitch. COM 100 3 2133-2136 *FD autostowed, probable power glitch. COM 100 3 2150 %KP WEA: Overcast skies, increasing clouds, t-storms in the vicinity, precipitation starting. 2319-2323 *PT autostowed, probable power glitch. COM 100 4 0000 Date is 2006AUG13/225. 0139 New operator is Jim Ogle. 0210-0211 *PT autostowed, power glitch. Repointed. COM 100 1 0326-0327 *PT autostowed, power glitch. Repointed.
