- Kapton washers to prevent picomotor sticking were installed on the HAM6 picos in the morning.
- Cable grounding were checked with Dan after Jim's cable rerouting in the evening. (Entry below)

The last ISC task before puting the north door is alignment of the OMC leakage trans beam on the northwest viewport (emulator).
With 2W PSL input, corresponding to 3~4mW on the OMC, I expect 20uW transmitted when the OMC is locked and well aligned.
It is probably tough to find.

We might just barely be able to see this beam with a CCD + zoom lens. Otherwise, we need to rely on increasing the input power to 10W.
