              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Restarted the hub and tcc. Reset the axis controllers and zeroed the NA2 rotator. Checked DIS slitviewer versus spectrograph focus. Created new slit masks for the DIS 0.9, 2.0, and 5.0" slits. Did a Shack collimation check, and no changes were necessary. Did a 100-star pointing grid and committed the pointing model.
Most of the night was clear, aside from some clouds in A half.
