n1 n3   s2  

### TARGETS ###
Laser
Achernar (HR 472)

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

Files 0 to 100 had a bright green laser, fainter red laser.
N3S2
One set of Achernar fringes on N3S2 with nominal lab alignment
One set with focus tweaked (to essentially starting position) plus
M15 and TT mirrors adjusted slightly. Fringes at about 0 (+200?)
N1S2
Indexed N1 near to the azimuth we planned to use. Achernar was acquired right away. Fringes at +500.

Note that neither North nor South had great beam quality. North tip/tilt had visibly poor image quality, but the pupil was fully illuminated. South tip/tilt looked small, but the pupil was only illuminated centrally.
