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.
Both Chrystal and Diode filters check out OK. No debris or discoloration of any significance noted. Added 125ml of water to the Crystal chiller. Diode chiller water level is good.

No reappearance of RF noise. Jeff B. just alerted me to a fire burning on the other side of 240 looking out between the arms. LOG: N/A
Have remained in observing. No reappearance of the RF noise.

QUICK SUMMARY: Some RF45 shenanigans on Patrick's shift, but hasn't returned yet.
All green and clear at this time. No issues with RF45 noise. The wind is up a bit (mid to upper teens with gusts well above 20), which has correspondingly excited primary microseism. Range has been hovering around 65Mpc.
TITLE: 07/01 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC STATE of H1: Observing at 67Mpc INCOMING OPERATOR: Jeff SHIFT SUMMARY: First lost lock at 18:14 UTC. Made it back to NLN with no real problems. Upon reaching NLN the RF noise was highly elevated. Talked to Keita (forget he was on vacation), then Vern, then Richard. Richard instructed me to try lowering the modulation depth until it settled and then bring it back to nominal. Lowering the modulation depth did not seem to have an affect. Eventually the lock broke at 19:43 UTC. After sitting at DOWN for a while the RF appeared to settle and I tried relocking. After a few lock losses along the way I made it back to NLN. At that point the RF noise appeared gone. I ran a2l and put the IFO into observing. No issues since. LOG: 21:08 UTC Powercycled video2 See earlier alogs.
Ran a2l. No SDF differences. RF noise is gone. Back to observing at 21:11 UTC.
Lost lock at 18:14 UTC. No obvious cause. No real issues reacquiring. Sitting at NLN and the attached are the DARM and RF45 spectrums. No SDF differences. No guardian notifications.
Coherence attached.
Range plot attached.
On phone with Richard. Told me to try adjusting the range down and then back. 19:43 UTC Lost lock adjusting H1:LSC-MOD_RF45_AM_RFSET
20:02 UTC Currently sitting at down. RF9 and RF45 are back to their references. 20:04 UTC RF45 glitched and came back to reference. 20:07 UTC Starting attempt to relock. 20:13 UTC RF45 glitched during DRMI states. 20:19 UTC Lock loss from SWITCH_TO_QPDS. 20:26 UTC Lock loss from LOCK_DRMI_3F. 20:58 UTC Made it to NLN. RF appears better. 21:02 UTC Running a2l.
