Night Assistant: 
Leonardo Paredes
Also Present: 
Andres Plazas, Chris Davis and Diego Capozzi
Problems: 

The observing started at 21:10 local time, later than normally, due to presence of precipitation in the sky at East. The observing started once the weather situation reached stability. Because of the late start, the standards measurement was not carried out.

The rasicam and environment windows of the telemetry viewer haven’t been working properly since 19 UT of 29th of September until present time. In particular thay have been showing constant values. The problem has been reported to Anne Elliot who is looking into it. Anne said she is going to ask Klaus and Liz who have been working with the telemetry database in the past few days. Waiting for instructions.

Several technical problems:
1) Had to restart TCS (GUI and then APP) twice for solving problems related to the loss of environmental info in the telemetry screens.
2) Quick Reduce stopped continuously over all night and had to be reset each time.
