              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
NICFPS is down at checkout, looks like the ICC isn't responding (I can't VNC into it).  Bill said ICC is dead tonight.  He submitted a PR.
The Dataq PMSS is not responding/could not open acquisition device.
We may need a new mask for the 5.0 arc sec DIS slit.  I noticed it was slightly mis-aligned tonight.  I will try to do that tomorrow afternoon during checkout.
Clouds started coming in around 04:00, we observed thru them but they got worse towards the end of the night.
No telescope problems.  The DIS shutter issue would come and go during the night.
