Night Assistant: 
Alberto Alvarez
Problems: 

1) During the time for afternoon calibrations, the names of the current filter had changed.  Instead of the filter being called "JX", the filter was called "_JX".  This didn't cause much of a problem until it was time to take darks.  The dark scripts only work if the filter is called "DARK".  Marco performed a quick fix for this, but it will need to be revised. 

2) When takening dome flats, the script tool normally has control of the lamp intensity level.  We could turn the lamps on to take the "On" lamps, but we could not turn the lamps off through the tool.  Javier found a problem in the lamp contol box.  He will work on fixing this tomorrow.

3) Public wifi was completely unstable most of the afternoon with the connection dropping every 10-15min.  It has been more stable during the night.

4) Operator's computer is very slow to refresh with the TCS so it is almost impossible for the operators to work.  This need to be fixed tomorrow so we can continue observing.

5) Bar on GUI that shows disk space states that the disk usage is 0GB.  df -h states disk usage is 1.2TB in /data.

Comments: 

Spent the first 6 hours of he night working with Rolo and Omar on the guiders.  We were able to determine the orientation of the guide cameras and select guide stars.  Aftrwards spend time testing imagae quality with a sequence of 600s exposures with the guider on and off.

Spent the 2nd half of the night taking some deep images for testing.
