Shift Details: 10/15/2016, Evening Shift 23:00 – 07:00 (16:00 –00:00) All times in UTC (PT)

Shift Summary:  IFO locked at start of shift. Jenne is commissioning. After lock loss, kept IFO down so Sheila can run some MC measurements. 

After relocking, just before 03:00 (20:00), PI modes 18 & 26 started to ring up. It took many iterations to get the modes to start to come down. When they were coming down they would hit a point just above the 1 line, drop straight down, then bounce back up. For a while the bounce backs were getting smaller and smaller. However, after a few minutes they started to ring back up. After many more tweaks both modes started to come down. After about 20 minutes both modes disappeared into the noise.
  
Environmental conditions were improving until about 05:00 (22:00), when the second round of storms start to move into the area. Winds are back up from Moderate Breeze (around 15mph) to Fresh Breeze (high 20s). Gusts are in the Gale to Sever Gale range (34 to 47mph). Both seismic bands are correspondingly elevating. To paraphrase W.C. Fields “It’s not a fit night out for man nor beast, or interferometry”.
