Summary:

• The duty cycle for this week was 59.93%, lower than previous weeks.
• Most locklosses were due to wind or commissioning
• The average range was ~150 most of the week, occasionally increasing to ~160 and dipping down to ~140 when there was low frequency noise
• The glitchgram showed 4kHz glitches intermittently throughout the week, and further searching reveals they’ve been showing up since April 8th with no apparent pattern. More detail on this has been posted in a separate aLog.
• Most days, there is a line of 20Hz noise in the corner accelerometers in the last 8 hours of the UTC day
• Hveto: there were 9 new channels that appeared this week
• FScan: all plots have appeared, the line count ranged from 100 - 850 (or 600 - 850 if we exclude the outlier on the day when LHO was only observing for 4.64% of the day), and never crossed the threshold.
