              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
The dis slit mask did not change back to the 1.5 arc sec slit for my 4th program.  The 1st and 2nd programs used the 5 arc sec, but I did my initial checkout with the 1.5 arc sec slit and the mask changed fine to the 5 arc sec slit after.  A starNubs of dcam fixed the problem.
No other problems and clear skies all night.
