CLIMB on beam 1,2,3

LT 20:32 = UT 04:32 = LST 01:14

LT 18:00 - humidity above 80%, high wind speed, 
   	   strong jet stream predicted, which likely results in bad seeing
LT 20:40 - humidity drops to 70%, opening one dome
   	   seeing is very very bad
LT 01:40 - opening up, wind speed decreased, seeing still very poor (2-3cm)

*** S1W1W2, W1=ref.

LT 01:45 - HD50277 (calibrator for FU Ori)
   	   
LT 02:00 - ksi_Gem (doing alignment)
   	   offsets: B2B3=0.397 cm
	   cannot find fringes on B1B2
LT 02:50 - tried on different stars, still no fringe on B1B2
   	   seeing even worse (1-2cm)
	   offsets: B1B2=-0.96cm
LT 03:00 - HD50277 (calibrator for MWC147)
   	   offset: B2B3=+0.378cm
	   could not find B1B2 fringe again
	   W1 is oscillating along elevation axis
	   (maybe same problem as E1, E2, which could be caused by low temperatures)
	   have to give up on YSO
LT 03:30 - Beta CMi = HD58715
   	   found again W1W2 fringe (short baseline), but not long baseline
	   W1W2 jump like crazy
LT 03:45 - closing W1,W2, keep S1 up to monitor the seeing
