SUPPORT: N/A

LOCK DURATION: Entire shift

INCOMING OPERATOR: Nutsinee

END-OF-SHIFT SUMMARY:  

IFO still locked at 78Mpc. Wind Calm. Sei and µSei remain the same. 2 more ETMY glitches. No further oscillations occurred. Curious that when LLO broke lock we also experienced a dip in BNS range.

MID-SHIFT SUMMARY:  

ACTIVITY LOG:

07:34  Oscillations: duration ~ 5 minutes. May correlate with a high SNR LF glitch that I observed on DMT Omega.

07:48 MICH (live) on NUC4 FOMW seems to be “breathing”  somewhere between 6Hz and 20Hz. Perhaps this is tied in with the previous log entry?

07:57 Oscillation: @08:04 IMC-F_OUTMON(tidal) grew to +/- 5 cts. ASC-DHARD_Y & P grew to +/- 2000cts. total duration is ~ 12minutes. Correlating(?) DMT Omega glitch shows up at approx the start time of the oscillation
