Echelle needed a pointing correction at the start of the night; the star was completely off the frame. Russet walked me through correcting the tertiary tilts. NM02 got started at 19:02, and we found that we had excellent seeing (0.68"), which persisted much of the night with occasionally worse spots down to 1.5".
B-half was uneventful with similarly good seeing, and we closed up around 06:30.
