It sure sounds like a haywire which needs to be fixed PROPERLY and should have been fixed properly a long time ago. If so, please do so. --jim On Fri, 27 Feb 2009, Howard Brewington wrote: > > APACHE POINT OBSERVATORY SDSS 2.5M > > OBSERVING LOG > Thursday February 26, 2009 > > (MJD 54889) > > ---=== OBSERVING TEAM ===--- > > Dmitry Bizyaev > Howard Brewington > Kaike Pan (swing and tech support) > Jon Brinkmann and Steph Snedden (tech support) > > ---=== OBSERVING PLAN ===--- > > Science! > > ---=== OBSERVING SUMMARY ===--- > > > ** THE TCC STOP_BUTTON IS BYPASSED AT THE INTERLOCK PANEL ** > > Some time was lost at the start of the night due to problems; see Prob Section. > > Added signal to: Cart 07, plate 3264 DONE > Cart 04, plate 3165-B DONE > Cart 09, plate 3242 DONE > Cart 08, plate 3254 DONE > Cart 01, plate 3236 > > WE ARE RUNNING OUT OF PLATES AGAIN !!!!! > > > ---=== OBSERVING LOG ===--- > > Afternoon: > > Systems were checked and working properly.
