### LOGDATE ###

### OBSERVERS ###
MJI

### WEATHER ###
Clear, no wind, few clouds (wispy ones only at the very start)
Wind started up at about 7.5 km/h according to ATCA (also registering at SUSI at about 7 km/h) at a similar time to when seeing went from excellent to good.

### LOCATION ###
SUSI

### PROGRAM ###
Rob de Rosa's survey targets

### SIDEROSTATS ###
 n3   s2  

### TARGETS ###
HR 472 (achernar, fringes found at about -1900)
HR 338 (fringes at about -2100)
HR 472 (achernar, fringes at about -2060. Continuous fringe lock, V^2 close-ish to 100% at times)
HR 338
HR 191 - Have to click "Int up" on acquisition. There should probably be a second intensifier setting for stars fainter than 4th mag in the catalog.
HR 338
HR 126  - no fringes because it is a binary and I'm pretty sure each siderostat acquired a different star.
HR 472
HR 338 - Stupid acquisition delay because I typed in 388
[hr 191 - more background issues and no fringes. strainge]
hr 472  - fringes at -2090
hr 338 - cooler turned off again. When finally re-acquired, the data quality was much worse. NB the north laser heater light was also flashing at this time.
hr 472 - confirmed that it isn't just the star - fringes definitely less stable.
*** Science over for 338, testing now ***
hr 472 - a data set with just the South laser metrology. Appears identical to the "both lasers set"
hr 472 - for completeness, a set with just the  North laser metrology
*** back to science, hopefully ***
hr 919. Still using the south periscopes. Adjusted dispersion (i.e. did a "tg") then took another set. Fringes around -1750 now.
hr 1088 ** No fringes found - search between -2000 and -1500 at least ***
hr 1173 : Reasonable fringes, right on -1710. 
hr 1088 : Got the fringes this time, -1710.

hr 3447 (maybe not a good cal, but should be a good fringe finder). Two data sets again - the first while adjusting the glass (from -1m of air to -2m of air)

### QUALITY ###
Very good (several calibrated points)  

### PROBLEMS ###
- Alignment needed to be tweaked at the start. I did N15, S15, NTT, STT and the North Zaber focus.
- Issues on re-acquiring the cal for zet phe then achernar. Almost certainly because I was playing wtih gains, and there was a fake lock.

North offset -34 -86
Sour offset -45 -28

- On the 3rd achernar acquisition (10pm) saw the background playing up again. Found that the camera had warmed up to room temperature! Cooled back down to -60C. This happened again, then I went to -40 celsius. I suspect that the cooling fluid isn't getting through, and the camera is going into some kind of cooler shutdown mode.

- When slewing from far in the West to the South-East, S2 lost its position and needed to be reindexed. Or maybe the pointing model was just bad. After a zoff the star came in pretty quickly.
