Overall Features:

• 52 Hz noise very variable to loud Example 52 Hz Noise Line Deviation - seems that it may have some correlation with LVEA acoustic noise (PEM) PSL table: Acoustic PSL Table Graph
• 180 Hz line seems to be excited more than normal several small time segments throughout the lock
• HVETO: H1:LSC-REFL_A_RF45_Q_ERR_DQ and H1:LSC-REFL_A_LF_OUT_DQ are new HVETO top 3 round winners, but are likely related to channels that have been in top three in previous weeks (according to drop plots)

Specific Day Notes:

• Monday June 12, 2023: 
  • 09:36 and 6/13 02:11 has some comb feature at low frequency: graph
  • LVEA acoustic has a louder line at ~ 320-330 Hz roughly in Outside HAM6: graph
  • 07:44 has a short broadband jump in noise in hourly h(t) spectrograms
• Tuesday June 13, 2023:
  • Lock starting at 06:53 seems to have more noise than normal at > 500Hz
  • Lots of low freq. noise starting up around 10:00 and getting worse until end of lock at 13:16: graph
  • Broadband acoustic noise at 22:00 (Brina points out it's probably wind!) : graph
• Wednesday June 14, 2023:
  • 23:33 burst of glitches from 20 Hz up to 150 Hz graph
  • DetChar/PyCBC graphs: Set of triggers that seems unusual at 12:30 to 14:00 and from 8 s down to 5 s template duration, doesn't seem correlated to anything else I found. graph
• Thursday June 15, 2023: Not much to note
• Friday June 16, 2023
  • Noise got a good bit lower according to normalized spectrogram after 11:00 lock started in low freq (below 30 Hz) graph
• Saturday June 17, 2023
  • Noise starting at 12:00 below 60Hz seems to correlate with earthquake
  • PyCBC:
    • 08:20-08:30 4-5 s template glitches including loudest of the day at 9.43 SNR - seems to also have a very low freq (11 Hz) noise in spectrograms at this time
    • 11:48 4-6s templates graph - seems to be definitely caused by Ground Motion (0.3 Hz - 1 Hz) and also shows in Anthro band graph. (double checked this is observing time) - alog notes this is EQ in Tonga: alog_link
• Sunday June 18, 2023: Not much to note
