8/23 OWL Shift:  7:00-15:00UTC (00:00-8:00PDT), all times posted in UTC

Summary:

Handed an H1 in NOMINAL_LOW_NOISE, but it was marked for Commissioning, so Jim took it to Undisturbed (6:56utc).  But then after he mentioned the temporary fix for the hobbling PRM, decided to take it out of Undisturbed (7:10utc with 50Mpc range) to run Evan's python script.  This took us up 10Mpc, and went back to Undisturbed at (7:19utc) with a range of 60Mpc.

• DARM Spectrum:  Looks pretty close to the spectrum (slightly under for 7-30Hz & biggish bump at 330Hz).  Glitches have been fairly minimal entire shift.
• Environmental:  Winds are dead and below 5mph.  Seismic bands all look minimal.  No smoke.

Shift Activities:

• 07:19 H1 Back to Observing/Undisturbed/OK/Science/Up/Data-taking Mode (not sure what we call this state in the aLIGO epoch, in iLIGO it was Science Mode) with OMC Whitening Added & Evan's script for removing bad  PRM LL OSEM.
• 10:42, 10:48, 12:09, 13:28, 14:34, 14:38 ETMy Saturations

PRM NOTE:  If H1 drops out of lock, one will want to see if it acuires without PRM's LL.  If it does not, then one will want to revert the matrix for PRM (see Evan's aLog or python script for matrix elements).  The script is currently saved on the Desktop of the Ops Workstation and can be run in a terminal (it takes about 1 min to zero out the LL elements).

Since we had some empty space on the nuc wall monitors, I put up a few items:  (I assume once we can run DMT Viewer on these monitors we'll put seismic plots on them.)

• nuc4:  ODC Master, Observatory Mode, and Intent Button (from Guardian Overview)
• nuc5:  Summary Pages (ER8 Summary, ER8 Time Accounting, H1 Operating Mode)---unfortunately all of these don't update on their own, so one has to refresh them by hand---it's nice to watch them though.
