              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Sutherland
No Echelle IOL or checkout image tonight - ICC is currently down.
MOS masks from last night are back in the black kosmos slit suitcase.
Dust kept us closed at the start of the night.
Ended early because sky would be too bright to continue with more exposures.
Overall a quiet and productive night with no telescope or instrument problems.
