13:50UTC addressing RF45 AM issue that has been ongoing for about 4.5 hours. Mike L and I decided to try a reduction in the LSC-MOD_RF_45_AM gain by 1dB to as per Stefan's aLog https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=21716
Mid-Shift Summary: IFO Locked @ 64Mpc (lower than normal due to funny business visible in DARM). No obtrusive Seismic or wind activity. 2 ETMY glitches. Some increasing activity in the lower DARM frequencies are causing drops in range. It just keeps bouncing up and down (see screenshots) Is this a combination of bounce and roll modes ringing up? This was the same activity that I noted in my transition summary. Is it from anthropogenic noise?
So this was due to the 45Mhz RFAM issue that H1 has been experiencing. With Mike L's help, I got an education on what it is and how to try and tame it in the days prior to it being rectified once and for all.

STATE Of H1: Observing
OUTGOING OPERATOR: Patrick
QUICK SUMMARY:. IFO Locked at 68Mpc/22.9W. No injections are running. All lights are off in LVEA, MID, END and PSL. Wind is <10mph. Microseism seems to be riding steady at ~.1um/s for the last few hours following an earthquake. EQ seismic took a little hop from ~ .2 um/s to .1um/s due to a small earthquake in the Portugal area. It appears that at 07:09UTC there was some raised level of noise activity in DARM from 25Hz and below. This only lasted about 1 minute.
TITLE: 09/25 [EVE Shift]: 23:00-07:00 UTC (16:00-00:00 PDT), all times posted in UTC STATE Of H1: Observing, ~67 MPc SHIFT SUMMARY: Recovered from two lock losses. The cause of the first is unclear. The second was likely from a 6.2 magnitude earthquake in Chile. After recovering from the earthquake I put it into commissioning mode to allow Chris to do hardware injections while LLO was down. He is done and we are back to observing. INCOMING OPERATOR: Ed
Terramon and GW Stat on nuc1 are down due to some kind of authentication issue.
We tested a set of waveforms to see if they would saturation the ETMY ESD. Test the 15Hz waveform Previously we have tested a waveform that began at 30Hz, see aLog 21838. It was requested we try it from 15Hz instead of 30Hz.

The ETMY alert happened a bit after the injection happened. SO I waited, I repeated the same injection, and there was no alert. I did one of these injections with a padding of 10 minutes so if the search groups are going to followup one of these injections in more detail this would be a good choice: awgstream H1:CAL-INJ_TRANSIENT_EXC 16384 ../H1/posterior0_1126259455.out 1.0 -d -d >> log3.txt # gave this guy a bit of time The start time of this injection is: SIStrOpen: Waveform starts at GPS=1127281956, epoch=0, sample=0 Testing the other nine waveforms Then I tested the remaining 9 waveforms by beginning with a scale factor of 0.3333 and incrementing to 1.0. I did these with little spacing between the injections so I do not think this set is worth the analysis groups following up.

I did not see any injection go above the 90000 counts. The highest was posterior0*.out which was near 80000 counts.
I am going to follow up the injections I passed to Chris. Assuming the "start time" is the time at the 1st sample of the injection file (and not the 1st non-zero sample) the end times of the increasing amplitude posterior0 injections should be around
The only ETMY overflows during the injection periods were: 1127278436.8 1127280154.9 (also overflowed ETMY L2 and OMC DCPD) 1127282847.5 None were related to the injections.
John V. has also provided 10 waveforms that I used for testing. The waveform single-column ASCII files that contain the h(t) time series can be found in the hardware injection SVN here: https://daqsvn.ligo-la.caltech.edu/svn/injection/hwinj/Details/Inspiral/${IFO}/posterior*.out
And the corresponding XML parameter files can be found here: https://daqsvn.ligo-la.caltech.edu/svn/injection/hwinj/Details/Inspiral/posterior*.xml
I will post time series plots of the waveforms as a comment later.
06:20 UTC Chris is done with hardware injections, back to observing mode
I'm done with the hardware injection tests. More details in upcoming aLog entry.
04:20 UTC Taking out of observing to allow Chris to test hardware injections
L1 is down at the moment. I am beginning some single-IFO hardware injection tests at H1 now.
03:28 UTC locked on DRMI briefly, loss lock, tripped BS ISI stage 2 GS13 04:09 UTC Back to low noise 04:16 UTC Back to observing mode
03:15 UTC lockloss, 6.2 Mag Earthquake, 30km SW of Ovalle, Chile, 02:51:18 UTC
23:48 UTC tour in control room 23:58 UTC video3 frozen, rebooted 00:26 UTC last of tour left control room 01:10 UTC problems with operator0 workstation, rebooted twice 02:06 - 02:11 UTC stepped out of control room Still in observing mode at ~ 70 MPc.
A tour group was on site this afternoon. Arrival time at LSB = ~3:00 PM. Departure time = ~5:15 PM. Group size = ~26 adults. Vehicles at the LSB = ~12 passenger cars. The group walked to the overpass near 4:15 PM and visited the control room near 4:45 PM.
23:23 UTC Back to observing. Only intervention required was moving the BS in pitch at LOCK_DRMI_1F. Cheryl states that it is acceptable that the 'Continuous Wave Inj Signal' on the Ops Overview is red and stating 'No Injection'.
TITLE: 09/25 [EVE Shift]: 23:00-07:00 UTC (16:00-00:00 PDT), all times posted in UTC STATE Of H1: Lock loss 10 minutes prior to start of shift. OUTGOING OPERATOR: Cheryl QUICK SUMMARY: Lights appear off in the LVEA, PSL enclosure, end X, end Y and mid X. I can not tell from the camera if they are off at mid Y. Seismic in 0.03 - 0.1 Hz band is between 10^-2 and 10^-1 um/s at end X and end Y. It is around 10^-2 um/s at the corner station. Seismic in 0.1 - 0.3 Hz band is around 10^-1 um/s. Wind speeds are ranging up to 20mph.
SUMMARY:
IFO relocked and was in Observe most of the shift.
4 large ETMY glitches in the second half of the lock.
IFO lost lock about 10 minutes before the end of the shift.
Currently relocked and on it's way to Low Noise.
