              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
I updated the sweet spot for the DIS slit.  It was sitting just above the 1.5 arc sec slit.  The DIS slit mask for the 1.5 arc sec slit also seems a little off (2 pixels high) for some reason.
I needed to take 5 mins of observation time to create a new 1.5 arc sec slit mask as boresight guiding kept failing.
No other telescope problems tonight.
