• STATE Of H1: Observing, 72 Mpc Range, 9 hours locked.

• SHIFT SUMMARY: Locked my entire shift, with no saturations for the first half. FMCS alarm at 2:15 UTC (see alog) that just seemed to pass though.
  

• INCOMING OPERATOR: Jeff B.

• ACTIVITY LOG:

• ETMY Saturations (in UTC): 3:25, 3:48, 3:58, 4:28, 6:01, 6:28, 6:36

Locked in Nominal Low Noise and Observing. Minimal glitches, no saturations so far, and the environment seems calm.

At 19:14 PST there was a critical alarm on H0:FMC-EX_CY_H2O_SUP_DEGF. By the time I got to it it was no longer in alarm. The EX chiller medm seemed to look normal to me, but trending the previously mentioned channel did show an odd flat spot in the supply temperature for the past ~3 hours (See attachments below). The tempurature began to increase again at 19:07 and seems to have gone back into its normal rythme.

I will continue to montior this.

Title: 9/19 Day Shift 15:00-23:00 UTC (8:00-16:00 PST).  All times in UTC.

State of H1: Observing

Shift Summary:  After a few false starts at lock stretches of significant length, H1 has been locked in Observing Mode for the last ~5 hours of my shift.  A few glitches related to ETMy saturations, but otherwise stable.  Environment: calm.

Activity log:

18:43 Evan arrives on site

DCS copies the H1_R raw science frames from CDS to the LDAS archive and the H1_C commissioning frames from CDS to the LDAS scratch filesystems. Currently the commissiong frames are also being copied to the LDAS archive. To fix a load issue on the LDAS side which was causing archiving of the science frame to fall behind, this latter process has been switch to primarily get its data from fw1. LDAS is getting the science frames from fw0, but now is getting commissiong frame for both scratch and archive from fw1. This should not affect CDS.

Once again back to Observing @ 18:11 UTC.

Lost lock again @ 17:47.  ITMx saturation, but again not obvious enviromental culprits.

Locked Nominal Low Noise @ 17:40, set to Observing Mode.

H1 has been relocked and set to Observing Mode at ~76 MPc.  I had to accept 2 SDF Diffs (H1:ALS-Y_WFS_DOF_3_P_GAIN and H1:ALS-Y_WFS_DOF_3_Y_GAIN) in order to go to Observing Mode.  There is still a notification present about SPM Diffs for SEI HAM5 (H1:HPI-HAM5_MASTER_SWITCH and H1:ISI-HAM5_MASTERSWITCH), but these did not prevent me from going to Observing, so I am ignoring them. 

Also, going through the checklist before setting Observing Mode, I had a question about sweeping the LVEA.  I couldn't find an aLog about this being done, so I called Corey.  He stated that this was being postponed until next Tuesday and that I could safely ignore this for now.  Nevertheless, the lights in the LVEA and PSL are all off and no one is on site besides Elli and Miguel who are in the CR. 

Title: 9/19 Day Shift 15:00-23:00 UTC (8:00-16:00 PDT). All time posted in UTC.

State of H1: Lock acquistion.

Outgoing Operator: Jeff Bartlett

Summary: A series of EQs in Chile have had the IFO down for most of the OWL shift.  They have rung down enough now that we should be able to lock.  Alignment looks good, so I will attempt to relock without initial alignment first.

Activity Log: All Times in UTC (PT)

07:00 (00:00) Take over from TJ
07:00 (00:00) IFO relocking after EQ lock loss
07:16 (00:16) IFO locked at NOMINAL_LOW_NOISE, 22.9W, 72Mpc
07:22 (00:22) Set Intent Bit to OBSERVE 
08:05 (01:05) ETMY saturation
09:56 (02:56) ITMX saturation
09:56 (02:56) Lockloss – 6.1 Mag earthquake near Chile
10:50 (03:50) IFO not locking – Run initial alignment
12:31 (05:31) While at LOCK_DRMI_1F BS ISI stage 2 WD trip – Reset watchdog
13:30 (06:30) BS ISI stage 2 WD trip – Reset watchdog
13:34 (06:34) Set IFO to DOWN while ring down from last EQ
14:34 (07:34) Received a GRB alert. IFO is currently down
15:05 (08:05) Turn over to Travis

Incoming Operatror: Travis

Shift Summary: 
- 09:56 (02:56) – Lockloss 6.1 mag EQ near Chile – Seismic activity rung up, but coming down rapidly. Will attempt to relock.
- 13:25 (06:25) – Another 6.2 mag EQ near Chile – Seismic activity has rung up again. Continue with relocking attempt.
- 13:34 (06:34) – IFO repeatedly coming up to LOCK_DRMI_1F and higher before losing lock. Put IFO in DOWN state until seismic activity calms down. Spoke with LLO they are also holding for things to settle down. 
- 13:45 (06:45) – Another 5.4 mag EQ near Chile 
- 14:34 (07:34) – GRB alert. IFO down at this time

Recovering from 09:56 (02:56) lockloss. Relocking failing at various points along the Guardian path. Had DRMI_1F catch in split mode a couple of times. A tweak of the BS corrected one, went down on the other before I could catch it.

As I was typing up a report saying how well things have been going, the ASC Striptool started looking bad. After a few minutes of this, it lost it.
