Program: CL2 (YSOs, PI: Millan-Gabet et al.)

Observers: Stefan Kraus, Rafael Millan-Gabet, John Monnier

Telescope: S2-E2-W1-W2
POPs:       5- 2- 1- 5

CHARA/CLIMB
Baseline: S2(pop5)-E2(pop2)-W1(pop1)
(S2 on beam 1, E2 on beam 2, W1 on beam 3, E2 reference)


LT 21:46 = UT 04:46 = LST 14:08

LT 21:55 - hd126035 (Lambda Vir calibrator)
	   found fringes at 2.0719 (E2W1=2&3), -0.919 (S2E2=1&2)
LT 22:50 - hd156365 (MWC275 calibrator)
   	   first fringe search not successful	
	   recording technical data without fringes, SYNC 500 Hz (=NON-DEST)
	   recording technical data without fringes, NORM 500 Hz (=DEST)
	   many time lost due to W1 cart stuck.
LT 23:30   VME crashed, have to reboot to search for fringes
   	   have to home carts
	   searching manually for fringe
	   test shows that the CLIMB buttons do not apply the offsets to the delay-line
	   to check this, turn off "OL" offset buttom (keeping "FT" and "MAN" pressed)
	   then click the bottons and the delay-line offset should change
	   after restart of climb, it works again
	   -> Problem identified: 
	   -> Solution: If VME crashes, CLIMB-server has to be restarted.
LT 01:?? - hd190327 (V1295Aql calibrator)
LT 02:15 - have to close dome to due high humidity (>85%)
LT 03:00 - taking one file in H-band to estimate background (technical test)
   	   saving data in H-band (*_001.fits) without fringes and dome closed
LT 04:00 - opening again (humidity 76%).
LT 04:00 - hd207920 (Omi Aqr calibrator)
LT 04:30   carts are vibrating, so we would have to restart VCM
   	   which would also interrupt FLUOR operation
LT 04:35 - since not enough time is left to make a new pointing, we are closing down
