In the past week we finished cleaning up the upper hex. In the process we had to move some of the cameras around in our internal views of the dome so the view located at:

This week we will be starting the metrology of the upper hex in preparation for putting on the upper and lower X rails. This metrology is done with a laser tracker and small “nest” mirrors placed around the telescope structure. Other activities this week will include finishing up the cable-ways in the lower electrical room and spectrograph room, work on the structure azimuth cable wrap, and work on the static cable ways. It is amazing the amount of power wires, optical cables, glycol and air lines that need to be strung up.

We are still right on schedule.
