CLASSIC on beam 5&6

UT twilight 03:36 -- 12:12

LT 20:27 = UT 03:27 = LST 13:08

LT 20:40   *** BASELINE S2W1:
LT 20:40 - Del Sco
   	   for alignment
	   searching for fringe, seeing 6-11cm
	   problem with delay lines
	   have to go to lab to fix it
LT 21:30   returning from lab, try it again
LT 21:35   again problems with S2 delay line
LT 22:03   scanned for fringe, still delay line problems
   	   offset = -4.307cm (22:16, HA-1:02)
LT 22:18 - HD140990 (K=6.4), seeing 5-8cm
   	   repeating alignment
	   recording SYNC 500 Hz (100 Hz Frg), offset -4.29 (22:27), -4.315 (22:35) , counts 60
LT 22:35 - HD142666, seeing 5-6cm
   	   finding fringes at -4.353 (22:43), -4.37cm (22:49) counts 70-90
LT 22:51 - HD140990
   	   cannot find fringes, scanning...
	   give up on this calibrator
LT 23:18 - HD141597
   	   recording NORM, interrupted
   	   recording SYNC 500 Hz, offset -4.497 (23:35), -4.455 (23:44), counts 60-70
	   lost fringes in between, but have enought frames
LT 23:45 - Delta Sco
   	   checking alignment again
	   problem with delay lines
LT 00:14   S2 cannot be made to work anymore
   	   (S2 cart sticks and vibrates)
LT 00:15   *** BASELINE W1E2 (B=250m)
LT 00:40 - HD190327
   	   alignment, searching fringes
LT 01:20   problem with carts
LT 01:30   find fringe at +1.706cm (01:31, clock 0.017)
LT 01:30 - HD189509, seeing 7-8cm
   	   recording SYNC 750 Hz (150 Hz Frg), offset -1.71 (01:36), -1.71 (01:41)
LT 01:40 - V1295Aql
   	   recording SYNC 750 Hz, offset -1.726 (01:48), -1.732 (01:53)
LT 02:00 - HD189509
   	   recording SYNC 750 Hz, offset -1.725 (02:03)
LT 02:10 - V1295Aql
   	   cannot find fringe
LT 02:30 - HD189509
   	   cannot find fringe
LT 02:50 - Tau Aql, to find fringes, seeing 5-10cm
   	   cannot find fringe, also FLUOR does not have fringes since about the same time
	   check delay lines, everything OK
	   found fringe at -1.816cm 
LT 03:15   V1295Aql is running out of delay on this baseline soon, so have can make only one calibrator
LT 03:20 - HD195194 (K=4.8), seeing 5-8cm
   	   doing NIRO alignment
	   find fringe 
	   recording NORM 500 Hz (100 Hz Frg) at -3.1345 (03:37), -3.144 (03:44)
LT 03:45 - MWC342
   	   close to zenith, altitude 85 deg
	   acquistion fails
LT 04:03 - HD197950 (K=5.0)
   	   recording NORM 500 Hz at -2.63cm (04:12), -2.58cm (04:20)
LT 04:20 - MWC361
   	   recording NORM 500 Hz at -2.54cm (04:25), -2.54cm (04:30)
LT 04:30 - HD197950
   	   recording NORM 500 Hz at -2.58cm (04:39)
LT 04:41 - MWC361, seeing 4-9cm
   	   recording NORM 500 Hz at -2.54cm (04:48)
LT 04:49 - HD197950
   	   recording NORM 500 Hz at -2.57cm
LT 04:58 - MWC361
   	   recording NORM 500 Hz at -2.54cm
LT 05:08 - HD197950
   	   recording NORM 500 Hz at -2.58cm
	   background is already quite bright on acquisition screen
LT 05:17 - closing down
