              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Weather was ok, partly cloudy most of the night. Axis controllers reset, NA2 zeroed out. Collimation was done with good results. We worked on the DIS slit focus. Some problems there, but by the end of the night it seemed to be ironed out. Will check with Russet tomorrow to make sure results are acceptable.
We were open all night.
