VERY LONG BASELINE ARRAY OBSERVING LOG -------------------------------------- Project: BJ045A Observer: Junor, Bill Project type: VLBA Obs filename: bj045acrd.* Date/Day: 2004JAN28/028 Ants Scheduled: HN NL FD LA PT KP OV MK =UT-Time===Comment===============================================MF#===%AD==AMD= Operator is Cyrus M Reed. VCLOCK and GPS DELTA OK. UT1-UTC OK (-0.41). WEA: Cloud cover via webcam unavailable; WEA: Night at all sites. WEA: No recent precipitation @ any site. 0714 Begin observing. Antennas on source. MK starts later @ 0907UT. MK Tape EVNT0603 was on drive #2 during this project with 10 - 11 passes being used. MT404 was written on the same tape afterwards. We believe that the second project did not overwrite data from the first. However, as a slight chance exists, this comment is being added to the log. -dwp 0714-1336 %FD 3mm receiver is slightly warm @ 33K. 0714-1336 *KP 7mm LCP Tsys is 3x RCP levels. 13274 25 95 0907 MK now observing and on source. 1315 WEA: SC Cloudy.
