UT 2010-Jul-10 ============== Program CL3, PI Kraus Observers: Fabien, PJ CHARA/CLIMB TEL S1-S2-E1-W1-W2 POP 1-1-4-4-2 TRIPLET S1-S2-W2 (start-up) BEAM B1-B2-B3 REF CART W2 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.
