Observer Support: 
Alberto Alvarez
Night Assistant: 
Leonardo Paredes
Also Present: 
Katie Kaleida
Problems: 

At the beginning of the night we have problems with the system (GCS). It was needed to restart SISPI a couple of times and then cycle the cranes to establish 
conection. About 15 minutes were lost in this operation.

The system operated with no problems for several hours, from 7:30pm to 1:30pm.

Then, major problems appeared at 1:34am (local time). Some images were not being Built. This started in image 227117. We tried restarting IB1 to IB5 but the problem continue.
We restarted SISPI a couple of times and did not solve the problem. Katie Kaleida got support from an Ann Elliot through skype and it was determined that there was a problem of connection with the filters. It was going to be necessary to cycle the filter power but the night assistant did not know the procedure for that. After several hours and consultation with several people it was clear that it was not going to be possible to solve the problem durng the night. At 4:15 am we decided to close for the night.  The day crew will need to look into this tomorrow so that we can be back on sky by the evening. Thanks!
