Summary:

• Daily observing duty cycle: 87%, 32.3%, 66.2%, 43.8%, 71.3%, 73.9%, 91.9%. Week average: 66.6%
• Observed noise lines in h(t) occurring intermittently, particularly at 15, 29, and 32 Hz, throughout the week
• Lock-losses mostly caused by hardware/power issues, earthquakes, in some cases it looked like an earthquake caused a lock-loss but I could not find an obvious candidate in USGS
• High microseism throughout the beginning of the week, range floated in the 140-145 Mpc range from Mon-Wed, began to improve once microseism had calmed down in the latter half of the week
  • Mon had both high microseism and high winds, however the detector managed to ride out most of it
• Not much observing time on Tues due to maintenance
• On Thurs the detector lost observing time due to a hardware problem + alignment difficulties when attempting re-lock
• On Fri we noticed a regurly occurring ground motion in the corner station, which was picked up by multiple sensors and was weakly coupling to strain, as reported in this alog
  • Feature had appeared before, but not with the same frequency/regularity
  • Persisted throughout Fri/Sat, on Sun it changed and is now occurring less often, and more sporadically
  • Similar feature sometimes seen at LLO
  • DetChar suggested to follow-up by upconverting microphone data to audible range to help identify a cause
• Better duty cycle and range during the weekend, Sun in particular was very quiet (almost to 160 Mpc on Sun)
• Re-appearance of comb associated with OM2 heater (alog), later seemed to change frequency spacing
• Few PyCBC triggers with chi2-weighted SNR above 10
• H1:SUS-ETMX_L3_OPLEV_PIT_OUT_DQ and H1:ASC-DHARD_Y_OUT_DQ were frequently in the top two Hveto round winners for the week
