              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Bradley
The night was clear with decent seeing.  Overall productive.
The problem with slit masks not changing with the slits is still present on dcam.  I saw it during second half, the users were frequently switching between 0.9" and 5.0" slits.
