Starting
LT 21:20 = UT 00:00 = LST 00:00

r0 = 3-8cm, cloudy

LT 21:40 - Searching for fringes on HD140990 (cal for HD142666) S1-S2 -- could not find them -- homing carts
   	   Carts homed and seemed ok
	   searched -5cm/+5cm, nothing found
	   lost ticks ... 
LT 22:40   switching to HD164031 (cal for MWC275)
   	   lost tip/tilt due to passing clouds 
	   on standby
LT 23:12   got fringes on HD164031 on S1-S2, offset: -146 um
	   however lost tip/tilt immediately after
	   sky now fully covered with clouds -- going on standby
	   
LT 2:30	   switching to the second baseline configuration 

TRIPLET   S1-E1-W1  
BEAM      B1-B2-B3
REF CART  W1

homed W1 as it would not move
E1 tip/tilt acting weird (not enough flux even if counts high and debias done)
mbias done ttcs restarted, no effect. S1 still working.
Too many clouds anyway, and even MWC361 is too faint to keep tip/tilt locked.

LT 4:00 No improvement.

Summary
--
Too many clouds. Confirmed that CLIMB code at least works (found fringes on a calibrator) but no data secured.
