TITLE: 11/20 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 115Mpc
INCOMING OPERATOR: Ed
SHIFT SUMMARY:
H1 locked for ~16.75hrs.
Energy Committee visiting site. Wind fence work continues; BRS has been needing to go to the Damping state today (which is concurrent with when Wind Fence work started this morning).
Little over 2hrs of Calibration time was taken on H1.
Had a couple of EQ alerts (but no action taken for either). And ended shift with a 6.0 incoming EQ for Ed!
LOG:
- Optics Lab work:
- briefly just after 16:00(Vlad)
- 17:06 Dripta
- 18:49, 21:19-0:04 Jason working on SQZ NPRO laser.
- 16:24 Candidate alert received (& later retracted)
- 17:11 Eric G. wind fence check (~10min)
- Vanessa at MX & then to pick up Dewar/Norcal receipts on both arms
- 19:02 Received notice for EQ south of Japan (was listed as 5.6, but USGS updated it to 5.0). Will monitor.
- This was mostly a dud: Although this was squarely in the Earthquake zone, this one did not show up noticeably on site (nothing on the SEI BLRMS plot); so no SEI action needed.
- 19:09, 23:00 MY trip (Kyle)
- 19:45, 21:13-21:50 Heading to MX (Kyle)
- 20:00-21:00 (noon-1pm): Virtual Visit. Camera will be broadcasting in the Control Room.
- 20:09 Candidate alert received (& later retracted)
- Sudarshan notifying us of leaving his car (black toyota corrolla) in parking lot over weekend.
- 21:00 Out of OBSERVING
- 21:00 - 23:08 Calibration Time (Jeff, Vlad)
- 23:08 - 23:13 UofO visitors peak in LVEA (Robert)
- 21:18 Wind Fence visit (Hugh)
- 21:22 Incoming EQ alert received. It's borderline, so will monitor to see if action needed.
- EQ was sort of a dud: This was also squarely in EQ zone, but did not see anything detrimental enough to require action....at first.
- A min or two after the estimate for R-wave passing through, saw the BLRMS seismic signals kick up a little (on the wall computer, the peak made it up to 0.3um/s, and finally subsided 25-30min after the R-wave estimate.)
- 23:14 Back to OBSERVING
- 23:16 - 23:43 UofO visitors up to roof (Robert)
- 23:44 Noticed small step UP for H1:ISC-C_RF_SQZAOM200M_OUTPUTMON; don't see drastic drop in range...yet. (see attached)
- 23:58 EQ alarm received (6.0 magnitude from Laos)
