LT 20:52   *** BASELINE S1W2 (190m)
LT 20:52 - Del Sco, for fringe finding
   	   alignment, some repairs in the lab

LT 22:12 - Del Sco
	   problem with fringe search (delay lines do not move)
	   recording data NORM 1000Hz, offset -0.05cm
	   FLUOR did a clock sync (data looked strange on screen, maybe problem?)

   	   recording data NORM 500Hz, offset +0.24cm
LT 00:06 - calibrator ???
           (HD buttom was not pressed, so this was not HD188385, 
	   instead it was an earlier calibrator around RA=16h, either HD150366 or HD143900)
	   record NORM 500Hz, offset +0.47cm to +0.49cm
LT 00:25 - V1295Aql
   	   star does not show up in W2

	   in some individual frames slightly saturated, record nevertheless, maybe cutoff upper 10-15% in data reduction
LT 03:27 - V1297Aql, seeing 5-9cm
   	   cannot find fringes, go back to calibrator
