- Corey, Andres, Jeff, Cheryl

TMS Upper structure was attached to the ISI today.  Cables are routed to head toward their ISI brackets.  Jeff and Andres dressed the cables coming through the upper mass to be not touching the upper mass or rubbing against eachother.  One issue with dog clamps came up - waiting on an answer from SYS for a fix, if any change is necessary.  One wayward bolt may need to be rescued from the top of stage0, with no chance of moving on it's own.

I started cleaning optics on the ISC table, and the lights from the clean room were so strong I could not see the particulate on the optics that I easily observed before.  Possible that Corey's cleaning got a lot, but big particles on two optics that I've been tracking were still there.   Some options are to cover more lights with foil, or move the telescope down to the darker end of the room.  Doesn't look like the clean room is wired so I can turn lights off without turning the fans off, but maybe I missed something.
