Test T415139 SNEWS alarm went off with a request to acknowledge and I am not familar with how to acknowledge the Test.
 

TITLE: 07/04 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 145Mpc
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 6mph Gusts, 4mph 5min avg
    Primary useism: 0.01 μm/s
    Secondary useism: 0.10 μm/s 
QUICK SUMMARY:
Inherited an IFO that has been Locked for 4 hours and is in Observing.
Violins look pretty decent and are on their way down.

 

TITLE: 07/04 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 146Mpc
SHIFT SUMMARY:

Lock #1:

• Lockloss @ 08:11 - no obvious cause: alog

Lock #2:

• Relocking went unassisted (needed INCREASE_FLASHES for X-arm and PRMI)
• Waited in OMC_WHITENING for about 1.5 hours for violins to damp
  • Spoke with Rahul as he's been monitoring these violin ringups. We're still unsure as to why they're being kicked so much following a lockloss, but we agree that the nominal full-power damping settings are still working. Might be worth trying on next lock acquisition if they're rung up again to carefully increase some of the damping gains to save time (Rahul would like to be on standby if this is done)
• NLN and Observing @ 10:50

Handing off to Tony for the day.

LOG:

No log for this shift.

Since there won't be a maintenance window due to the holiday today, I've disabled the automatic start for both the magnetic injections and in-lock charge measurements so we can continue observing. I did this by taking both the PEM_MAG_INJ and SUS_CHARGE guardian nodes to DOWN.

State of H1: Observing at 145Mpc

Relocking was straightforward following the earlier lockloss save for waiting 90 minutes in OMC_WHITENING for violins to damp (seems to be the norm these days). Now back observing for the past 15 minutes.

FAMIS 19983

Lockloss @ 08:11 UTC - no obvious cause that I can determine. Lockloss tool analysis failed for this lockloss.

TITLE: 07/04 Owl Shift: 07:00-15:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 143Mpc
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 7mph Gusts, 5mph 5min avg
    Primary useism: 0.01 μm/s
    Secondary useism: 0.10 μm/s
QUICK SUMMARY: Taking over from Ryan C. H1 has just been relocked and has been Observing for the past 20 minutes at 143 Mpc.

• All systems look good, wind and ground motion low
• Wildfire near Benton City is still going, noticed the glow and flames around the Rattlesnake slope as I was driving in

TITLE: 07/04 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 145Mpc

SHIFT SUMMARY:

Lock#1:

Superevent at 02:12

EX saturation at 03:58

Lockloss at 04:02UTC

Lock#2:

Same ISC_LOCK code error as as happened in my past two locks, this time it happened twice in a row

After over an hour of damping violins in OMC_WHITENING, I recovered Observing at 06:37UTC

LOG:

No log for this shift

No obvious cause for the lockloss

The fire appears to be out, I can't see anymore smoke. We've been locked for 2:47, in Observing since 00:20 UTC. Everything seems stable.

TITLE: 07/03 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 145Mpc
SHIFT SUMMARY:

Shift for the most part was nice & quiet but then fires (photo attached) & earthquakes!  (but H1's on its way back).

Mentioned to Ryan that if there is any catastrophic/unsafe incidents (i.e. fire) which are a cause for concern/safety---he should think of his safety first and leave when comfortable.  Also mentioned it's probably to keep H1 in a DOWN state.  Then notify Mike/Richard/Keita (in place of Jenne this weekend).  And give a status update on the alog.  (hope this all sounds right!)  Also:  we have binoculars in the Control Room---in the back corner on top of file cabinet near the white board.)

• LOCKS:  First few locks have been dropping out due to lingering EQ motion
• LOCK#1:  Only stayed at DRMI a few secs and guardian took to PRMI (it locked at low values, but ASC maximized).  Lockloss at CHECKAS SHUTTERS
• LOCK#2:  lockloss at FIND IR
• LOCK#3:  Currently just powered up to 25W & Handing this lock off to Ryan C.

LOG:

• 1829-1831 Noticed that UPS arrived on-site
• 2014-2140 Labview work in PCal lab (Tony)
• 2018 "Incoming EQ" verbal alarm (M5.4 from Azerbaijan area.....note:  USGS webpage on nuc31 does not show this EQ with it's zoom on the earth).
  • 2045 begin to see oscillations on Picket Fence
• 2048 Landry phoned in to inquire about a fire in the Benton City area.
  • 2105 Went up to Observation Deck with binoculars.  At this point it was hard to see & might be dying down.
  • 2145 Picks back bigger than initial plume!
• 2112 "Incoming EQ" verbal alarm (M5.7 from Vanuatu)
• 2138 "Incoming EQ" verbal alarm (M4.8 from Vanuatu)
• 2148 LOCKLOSS
  • EQ Mode activated 3min after lockloss

TITLE: 07/03 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Earthquake
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 16mph Gusts, 12mph 5min avg
    Primary useism: 0.05 μm/s
    Secondary useism: 0.10 μm/s
QUICK SUMMARY:

• We're currently relocking at MOVE_SPOTS
• CDS/VAC/Dust looks good, Violins look high I anticipate having to spend a while damping them like I have been the past few days
• I'll continue to monitor the wildfire from the site cameras

Mike initially phoned in about seeing this fire from town 90min ago.  It looked like it had died down 30min later, but it has since returned.  

From here fire is behind the Rattlesnake Mountain "Slope" area (kind of where Hugh used to live).  Only see smoke at this point, and no flames seen from this side.

H1 continues to purr along nicely with a range hovering around 144Mpc & with 14.25+ hrs of lock.  Winds have slightly increased through the shift (but still with gusts barely touching 25mph).
