*** E1W1W2, W1=ref.


start: weather clear, humidity 40-65%
r0 = 5 cm
scan length LONG


Late start due to FLUOR trying to tweak the tip/tilt for VEGA.

need to use NSUM = 25 for tip/tilt
elevation too high anyway

summary of observations:

MWC 863 1 bracket (2T only) 

MWC 614 3 brackets

No luck on MWC 340 (close to the zenith + tip/tilt issues + very faint, made tip/tilt lock impossible), may be too hard to do with the current configuration in June.

CHARA object 320137 (cyg OB2 #9)  1 bracket for the FLUOR team

Tomorrow the targets HD142666, MWCD863 and MWC340 will be prioritized.
