TITLE: 12/17 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: Busy afternoon! We changed plans a bit after we remembered that the HAM7 crew needed the IMC locked for their scattered light investigation, so work in HAM1 and the PSL to prep for JAC installation was put on pause. Locking the IMC went fairly smoothly; MC1, MC3, and the IMC PZT were moved back into alignment based on top-mass OSEMs from when the IMC was last locked, and once the light pipe was reopened, the IMC locked without issue. Input power was brought up to 10W at the HAM7 team's request. Scattered light work in HAM7 will continue tomorrow, but for tonight we've shut the PSL light pipe and lowered input power back down to 1W since chambers are open.
