              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
The 1.5 arc sec slit mask seemed a little off (moved vertical but still horizontal to slit) tonight.  I also needed to re-adjust the slit center slightly upward.  We might want to check to make sure the 1.5 arc sec slit is secure in the wheel.  The current mask seemed to work fine, it was just off slightly.
The 5 arc sec slit mask was also a little low.
No problems otherwise and a nice clear night once the small patch of clouds moved through at the start of the night.
