### PROBLEMS ###
On start-up, I could not get either stars or the laser on pavo. After taking a break for my nightly chat on the phone with my wife, I decided to try a bright star (alf Pav), and to my surprise, I found it. It was very dim on pavo, however. To make a long story short, I eventually figured out that the apertures had been left in the beams.

Alf Pav was then very easy. I went back to try science, but fringe tracking on my calibrators (Vmag ~4.7 and ~4.8) was very unreliable. I was eventually able to get 100s of integration on each with dispersion turned off on Pavo, but it performed very poorly even compared to 2 weeks ago with the still glitching siderostats. Somewhat tentatively, I will blame the trouble on seeing. Fringes were found at -650 and -400 um.

Lately, N1's auto collimation position has moved from night to night. Tonight, it was right where it was expected. Perhaps, I managed to fix a loose encoder wire during the rewiring. The pointing models for both N1 and S2 desperately need improvement, however. Final pointing offsets for N1 were 225, 2. For S2: -80, 23.
