tried cal1 (faintest) but now saturating a bit for some reason ...
last bracket will not end with cal ...
start new bracket

tried SHORTSCAN but still some saturation ...
used 1/2 apertures ...

ut 05:20 hd211274 cal2
weird ... counts have come up again on one pixel and we are saturating ...

go to cal1 which is a bit fainter ...

ut 05:30 hd222173 cal1
+5363um / -2588um

NIRO ALIGN 
improved flux in 2 of the pixels
use 1/4 apertures

elevation too low for one of the telescopes ...
done with this target.

ut 07:00 going to omi Tau to INIT telescopes
NIRO ALIGN

not sure E1 is pointing well ...
star appears oddly shaped on FINDER ...
go to Rigel to be sure of E1 pointing ...
we can clearly see that something is blocking the light into FINDER
it was the finder cover!

ut target AB Aur = hd31293
had to put 1/2 apertures to avoid some saturation
not finding fringes ...
now software seems to be in bad state, cannot get fringe search GUI ...
restarted NIRO server
looked for fringes on shorter baseline E2W2 in various modes/rates
no fringes

UT 12:05 - out of delay.

Summary:
--------

S2E2W2
+ kappa And: 9 brackets. 

S1E1W1:
+ RY Tau: 5 brackets.

S2E2W2:
+ AB Aur: attempted but found no fringes.
