- CO2 laser on the TSCX table had run overnight, no issues with temperatures or output power. Was turned off at 1015 local time for some testing by Aidan, as he was looking at the dark noise of the ISS PDs.

- Corner Hartmann table optics continued to be mounted and positioned. Minor adjustments made to the position of some on-table cables.
 
- TCSY laser table work: continuation of alignment attempted but due to some irregularities in the positions of the first few optics (beam splitter, polarizers), with regards the relative positions of the laser and periscope, the co-ordinates of the table holes were relabeled and the table layout will likely need to be adjusted slightly.

TSCX laser was turned on again at ~1715local and will run overnight. Table doors are locked. 
TSCY chiller and power supplies have been left running, TCSY laser is turned off.
