Biggest problem seemed to be a glitching BeamSplitter OpLev laser. Per Jason’s instructions Sheila and Vern, made a power adjustment to the OpLev laser, which helped to quiet the glitching. For the past 4 hours, the IFO has been locked in observing mode. Power is 21.9W, with a range of 82.5Mpc. The wind has calmed down a bit (7 – 12mph range), seismic activity has been holding steady around 0.07um/s. Microseism remains around 1.0 – 0.8um/s, however the amplitude may be decreasing a bit. In general, the second half of the shift has been good for observing. The instrument has been stable and environmental conditions are not causing any issues at this time.
