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 59Mpc INCOMING OPERATOR: Cheryl SHIFT SUMMARY: The smoke from the fire seems to be dissipating. There have been numerous loud low frequency glitches up to around 100 Hz for the last couple of hours. They do not appear correlated with RF noise. LOG: ~18:15 UTC Mike and Marilyn to observation deck to check on fire. 18:21 UTC Mike and Marilyn back. Report some smoldering areas. 18:24 UTC Mike and Marilyn leaving site 19:24 UTC LLO down. Took out of observing to run a2l. 19:43 UTC Back to observing.
For the last hour and a half or so there has been an almost steady occurrence of low frequency glitches up to about 100 Hz. These do not appear correlated with RF noise.
See attached screenshot.
Have remained in observing. Mike and Marilyn stopped by and went to the observation deck to check on the fire with binoculars. They reported some smoldering areas.

STATE of H1: Observing at 64Mpc
INCOMING OPERATOR: Patrick
SHIFT SUMMARY:
H1 has been humming along (approaching 11hrs of lock). Had a PCalY alert (see below).
Fire Status: DOT has SR240 & SR24 road closures in effect atleast until noon when they reasses (attached is a closure map from WSDOT Facebook Page). Don't see flames or smoke plumes in the daylight, but it is still pretty hazy/smoky out. One can smell faint smoke in Control Room (have had possible smoke irritations during shift).
LOG:
DIAG_MAIN alarm: PCAL Y RX PD is greater than 1% off (have had this throughout the shift & Patrick said this is a known issue): TJ told me this is a known issue.
The PCalY Rx PD power variation is indeed under active investigation. While this has been known since October (see aLOGs 30827 and 30877 and attached image for Sep-Oct for original issue). Problem returned and was discussed in aLOGs 36208, 34153, 33108, and 33187. Problem is being noticed now again, since May (see attached image for Jan-Jun).

STATE of H1: Observing at 65Mpc
OUTGOING OPERATOR: Jeff
CURRENT ENVIRONMENT:
Wind: 15mph Gusts, 12mph 5min avg
Primary useism: 0.03 μm/s
Secondary useism: 0.05 μm/s
Sustained winds at beginning of the shift but appear to be dying down a little....luckily!
QUICK SUMMARY:
As Jeff has already summarized, this shift started with a fire burning out to the west (slightly north). As I drove in, SR240 was closed at the RT10 intersection. Mike was on-site with Jeff when I arrived. We could clearly see a fire line in the roof camera (& also by eye when we went up to the roof shortly after midnight). From Jeff's photos, and maps estimating the fire to be out on a hill/ridge about 18-19miles out (on the Umtanum Ridge which runs along the Columbia near Priest Rapids Dam and ends near the Vernita Bridge). We monitored the fire for a few hours and then after smoke obscured our view at about 1:30am, we had another view clear up at around 2:30am and at this time we could not see any flames. Mike left at around 2:45am. Called Hanford Patrol (non-emergency line) at 1am & then again at 3:05am & they had no update other than they are still fighting the fire.
On the scientific front, H1 has been humming along. It has been locked for 6hrs hovering around 65Mpc.
The grass fire continues to burn. The wind has increased and shifted, putting the site downwind. The fire is several miles away and on the other side of 240, so there is no immediate danger to the site. However, will continue to closely monitor throughout the night.
Grass fire still going strong and may be growing. Wind is in the upper teens to low 20s and out of the W to WNW, moving it towards 240. No immediate danger to the site at this time.
Per Hanford Fire via Hanford Patrol - The fire is about 10 miles from the site and is still to the N, NW of 240. There are fire units engaged, but could not give a containment assessment. Hanford Patrol knows we are here and will keep the control room informed. Have informed Mike and Vern of status.
Sheila, Richard, Jeff B. The lockloss at 03:01UTC was probably due to a tripped OMC PZT HV power supply. With Sheila and Richard's assistance, reset the power supply. Had to reselect the READY_FOR_HANDOFF state in the OMC Guardian to get the OMC to relock. Once the OMC relocked there were no further troubles getting the IFO to relock and back into Observing.
All was going well until just after 03:00 (20:00PT). Lockloss, reason unknown. Working on relocking. The grass fire continues to burn. It is across 240 and moving away from the site. Sky is getting hazy.
