UT 12 June 2013
CHARA/CLIMB - CL10 - PI: Millan-Gabet et al.

Observers: Norm, Rafael, Ming up here too.

Configuration:

beams 1-2(REF)-3 = S1-W2-W1 POPs 4-5-1: starting configuration
beams 1-2(REF)-3 = S2-W2-E1 POPs 1-5-4: backup configuration

20:00 local = ut 03:00 - still bright outside. some clouds.

20:30 
check star HD141513
NIRO align

21:00
closer check star HD144217 (warning: spec binary)
NIRO align
s1 offset +565um
w1 offset +4200um

22:00
trying to see if we can TT-lock on AS205A (V=15)
succeeded - 10msec / NSUM 20 / ~100000 counts on TT.

NIRO 500Hz / NONDEST / MEDSCAN

22:21
cal1 = HD144766
offsets +132um / +3200um
decent data, seeing OK.

22:45
target AS205A / CHARA ID = 320093
got the fringes, not tracking super-well ...
10-20 counts
+300um / +3200um
fringes not well overlapped most of the time ...

23:00
cal1 = HD144766
-118um / +2800um
counts ~ 50
but then fluctuating a lot 5-50 we don't know why...
we don't seem to be in a cloud...
we finished data sequence, but lots of low flux data...

check NIRO align - HD144217
needed some alignment

23:30
repeat cal1 = HD144766
-200um / +2700um
counts ~ 50

23:50
target AS205A / CHARA ID = 320093
10-20 counts
+30um / +2500um
no fringes very often...
aborted, not sure S1 is on fringe...
TT GUI not updating for some reason... comm stopped.
still not seeing fringes reliably, this is going to be a pain... ABORT.

a teenie winnie saturation on W2W1...

problem with TT comm again...

crappy fringes... elevation getting low again...
abort
