TITLE: 12/13 Owl Shift: 08:00-16:00 UTC (00:00-08:00 PST), all times posted in UTC
STATE of H1: Observing at 72.9978Mpc
OUTGOING OPERATOR: Patrick
CURRENT ENVIRONMENT:
Wind: 10mph Gusts, 8mph 5min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.15 μm/s
QUICK SUMMARY:
8:11-9:30UTC (12:11-01:30amPST): No Operator Coverage (Due to Winter Weather this week, I'll be taking the OWL shift for next 3 nights.)
Arrived to an H1 in OBSERVING & a quick scan looks like we have optimal conditions (range is at 70Mpc). Glancing at range over last 12hrs, range has 8hr period of going up to 75Mpc & down to 70Mpc(now) & I don't see anything seismically which matches that (useism has had a constant trend down over the last 24+hrs). There are also a few more glitches (i.e. drops in range) for this lock.
Low Useism: Seismically, we appear to be a tad under the 50percentile for useim (a comparison personal note between 90+percentile over the weekend & now is that the Tidal striptool is virtually flat vs over the weekend you would definitely see useism waves/oscillations at 90+%).
Violin Modes: Fundamental(~500Hz) looks to be just above 1e-19 on DARM. Second Harmonic (~1kHz) is just above 1e-15, this is the only notable feature on the "H1Glitches(DMT Omega)" tool on nuc0 (perhaps this is something which could be damped at an opportune time [Maintenance Day?]).
Talked with Fyffe @LLO to inform they are no longer flying solo.
Weather Conditions: No precipitation & cloudy.
Road Conditions: (driving in via Twin Bridges) Other than my driveway at home & driveway on-site, the roads were dry and clear (able to easily drive speed limit); made it to site in the standard 20-25min. I did come across a heard of deer right near the bridges.
The "2nd phone" heard in the audio recording from DetChar is the phone in the PSL enclosure anteroom. It is important to note that there is no call forwarding involved, both phones always ring if you call the PSL enclosure extension. The anteroom phone always lags behind the laser room phone though, which is why it appears to be forwarding the call. It sounds so faint because of the acoustic damping of the laser room (these phones are quite loud). Switching off the PSL enclosure phone turns off both the laser room and anteroom phones. This was tested this morning, as we can hear the anteroom phone from outside of the PSL enclosure; when the enclosure extension was called, no ringing was heard. To my knowledge neither of the PSL enclosure phones have the capability to auto-answer, they will continue to ring until physically answered or the caller hangs up.
