### OBSERVERS ###
MJI, ACR, BAW Testing, then ACR

### WEATHER ###
Incoming clouds, began alignment and testing at 9pm.

### LOCATION ###
SUSI

### PROGRAM ###
Test newly fixed North beam after vacuum pump was opened and pumped-down again.

Try some Sco-Cen binaries.

### SIDEROSTATS ###
  n4 s1   

### TARGETS ###
Bet-Cru (hr4853) for testing

Gain set to 230
Ksi02-Cen (hr4942) V=4.2: Fringes at -410um
f-Cen (hr4940) V=4.7: fringes at -420um
Thin Cloud so moving to brighter targets. Gain 200

Del-Cru (hr 4656) V=2.7: Fringes at -420um
Alf-Mus (hr 4798) V=2.6: Fringes at -200um
Tet-Car (hr 4199) V=2.8: Fringes at -520um

Gain set to 210
Mu02-Sco (hr 6252) V=3.5: Fringes at -190um.
Tau-lib (hr 5812) V=3.6: Fringes at -360um.
Pi-Sco (hr 5944) V=2.5: Fringes at -250um Losing tar quite often due to cloud.
Tau-Sco (hr 6165) V=2.8: fringes at -190um.
At this point I continually lost the star due to clouds. Closing


### QUALITY ###
 Average Quite bad (no/almost no useful data

### PROBLEMS ###
Old autocol N3: EL=359.563, Az=180.676


Cannot acquire Bet-Cru on S1. The LED was fine and the laser autocol was only just off the field of view. Eventually found star but it was very faint, due to the south focus accidentally having been moved while adjusting north focus. 

After focusing and optimisation the fringe fluxes are now
South: ~12,000
North: ~19,000

Tip/Tilt fluxes have a similar ratio. 
It really looks like North is significantly improved
