8/22 OWL Shift:  7:00-15:00UTC (00:00-8:00PDT), all times posted in UTC

Arrived to Commissioning on a locked H1, and L1 down for last 12+hrs.  Environemental conditions were nominal with wind dipping below 20mph & all seismic bands also quiet.

Want to reiterate that for ER8, we are deeming 1pm - 10pm (with L1 down) as the Commissioning window.  And I'd say if you need a measurement done during the 1-10pm window and H1 is locked, break lock in H1 and do your measurement if L1 is already down.

Additionally, before Evan, Dan, Stefan left, I made sure to have them clean up any differences on SDF.  Most were cleared up except for the OMC. 

After the Commissioning work, H1 has been locked the rest of the shift with nice range ~65Mpc & a few ETMy glitches dropping range.  DARM looks nice.  At times we seem to run below the reference from 10-20Hz.  There is also a bump at about 330Hz which is above reference.  H1 was much less glitchy for this OWL shift vs yesterday.

Shift Activities:

• 7:30 Dan & Evan out to LVEA for PLL set-up
• 8:30 Dan/Evan back.  Mentioned noise around HAM4 (transformer making noise and something else also making noise)
• 9:27 EY Dust monitor started alarming (not surprising with smoke in the air) with high counts for most of the shift on the order of tens of thousands of counts.
• 10:20 On CDS Overview noticed a CFC bit for H1OMC (due to Evan).  Load Coefficients was run to clear this.
• 10:25 With Violin Modes low, Added Whitening to the OMC (via OMC_LOCK guardian)
• 10:31  Went to Observing Mode
• 12:06, 12:38, 13:00, 13:55, 14:42 ETMy saturation
• 13:00 Gave a call to LLO to check on their status (because here they looked like they had good range, but on the GWI.stat page, their status is listed as "NOT OK".  Traced issue to their ODC Observation Ready bit (operator buttons were marked for:  Undisturbed & Observing)--  It was RED.  We then tracked this down to possibly a PSL excitation.  Gary was able to kill the excitation test point and they are now back to GREEN (i.e. OK + Intent).
• Handing off to Cheryl on this smoky morning.
