### TARGETS ###
Canopus (hr2326) - fringe finder, switched to bet-cru as Canopus is to large for 80m baseline
Fringes at 450microns, a litle bit patchy, V2 got up as high as 0.3

Set gain to 240 for the following:
Ksi02-Cen (hr4942) V=4.2mag, Fringes at 330 microns, very patchy.
f-Cen (hr4940) V=4.7mag, Fringes at 250 microns after a cart re-zero. very intermittent, had to search at speed 2 to find them.
Ksi02-Cen fringes at 230 microns. Lost the star after 75 seconds of data, couldn't get it back

Gain set to 210 for the following:
Pi-Sco (hr5944) V=2.9 Fringes at 330 microns much less intermittent than above but still patchy
Tau-Sco (hr6165) V=2.8 Fringes at 400 microns
Eta-Lup (hr5948) V=3.4 Fringes at 360 microns Fringes less intermittent at this point. 
Tau-Lib (hr5812) V=3.6 Couldn't get fringes on this one for some reason.
Rho-Sco (hr5928) V=3.8, again no fringes
Pi-Sco Fringes at 162 microns, much worse than earlier 
Tau-Sco Fringes at  Fringes at 220 microns
Rho-Sco Fringes at 120 microns
Tau-Lib Fringes at 90 microns Didn't finish this target 
Pi-Sco  fringes at 65 microns
 At this point, all of my server/gui windows froze. They returned partially after 10 minutes with ~20 "comms lo messages from k108" not sure what this is but it seemed like a good time to go to bed.




### QUALITY ###
 Average 

### PROBLEMS ###
On startup, pppd was down to all siderostats, restarted for s3, n1.
Also, shutter server was dead, had to kill and restart.

Something was clearly wrong with n1 elevation, server said it was at 340 degrees when it looked like it was closer to 20......I did a second index and that seemed to fix it. Upon slewing to target, I looked and saw it was back around 350 and trying to head to the target of 30. I let it go and it seemed to not really know where it was. I indexed again and the position changed dramatically. Something appears wrong with the index for this siderostat. I decided to switch to N4. 

South 3 acquisition on Canopus very easy with offsets -61 -103 arcsec.

North 4 acquisition was also easy with offsets -100 74


South metrology started getting quite weak around 40-45m and alignment didn't help. It was never lost though.

Shutters became unresponsive presumably during the bet-cru shutter sequence as north shutter was stuck open while acquiring the next star. 

Related to the above:
Once PAVO reconnected to shutter_server after the above crash, it lost N3 and once that was reconnected it lost the shutter again. This is a PAVO bug, and is currently fixed by restarting PAVO.


Had to reset the north 4 offsets (almost) every time I acquired, unsure as to why. This problem stopped happening when I started on the first Pi-Sco observation.
