H1 had an average duty cycle of 83.41% for the week, which is an increase from last week (78.1%).
A somewhat quiet (glitch and noise-wise) week for the detector.
Nine relevant seismic events throughout the week; five of these caused lock-losses (Monday, Tuesday, Saturday, and Sunday), while the rest caused some noise in the spectrograms in the 15-50Hz frequency band (Wednesday to Saturday).
The BNS range fluctuated from around 150 to 160Mpc throughout the week. On Wednesday, we had a significant 10MPc drop around 11:00-11:45 UTC; the corresponding aLog pointed “FC backscatter into the IFO” as the responsible.
On Tuesday we had eight very short lock-losses due to the OPO losing lock.
ETM glitches caused two lock-losses throughout the week (Tuesday and Thursday).
We observed persistent violin modes (specifically fundamental at ~500Hz, and some 2nd harmonics at ~1000Hz) following large lock-losses all week but on Wednesday. The most persistent one appeared later on Thursday and did not fade away until Friday morning. Last week the fundamental modes were also reported due to their persistency.
FScan Plots appeared everyday but on Monday. Lowest line count on Tuesday with ~2300 lines and highest on Friday with ~2900 lines.
