FAMIS 19979

Cooling: The chiller water temp seems to have dropped 6 days ago, cooling power meters, amplifiers, diode boxes, and control boxes slightly.

Environment: Temperatures in the laser room, anteroom, LVEA, diode room, and chiller room also dropped slightly at around the same time. Humidity seems to be falling everywhere, too.

Laser: This change 6 days ago also correlates with a drop in NPRO output power from 1.83 W to 1.82 W and a drop in AMP1 power.

Stabilization: PMC REFL is falling, but I don't exactly notice a corresponding increase in PMC TRANS. There was an ISS AA chassis failure 3 days ago (alog 70089).
