Telescope: 
CTIO Blanco 4-m
Submitter:

Observer Support: 
Mauricio Rojas
Night Assistant: 
Leonardo Paredes
Problems: 

We lost an hour at the beginning of the night.  There was a problem with TCS and Mauricio had to restart some things to get going.  When TCS came back up, we had a software interlock problem with the GCS_STATUS that was not solvable with restarting GCS from the architect console.  This ended up being fixed by killing and restarting SISPI.

 

Comments: 

 

None of the problems at the beginning mattered much because the night was very cloudy.
