Shift Summary - OWL

TITLE:  Oct 26 OWL Shift 7:00-15:00UTC (00:00-08:00 PDT), all times posted in UTC

STATE Of H1: Aligning

SUPPORT: Jenne

LOCK DURATION:

INCOMING OPERATOR: Cheryl

ACTIVITY LOG:

07:49 DARM “breathed” between 60Hz and 300Hz with no saturation verbal.

08:00 Wind speeds have picked up, sometimes gusting to 40mph.

08:12 Lockloss. More than likely due to high winds. µSei approaching .9microns/s.

08:30  Wind has dropped down to below 20mph. IFO is locking again.

08:50  Lockloss after being at  ENGAGE_ASC_PART3 for a minute or so.

09:01  IFO made it to RF_DARM then lost lock.

09:08 Wind picking up again to almost 30mph. This time the CS is taking the brunt.

10:00 Started switching GS13 gains to LO to get everything as damped as I can.

10:34 Re-Aligned/Isolated HAMs 2&3. GS13s switched back to high gain. IMC relocked. EQ band getting back down to 1micron/s

12:41 I’ve been having trouble trying to find my ALS spots. I’ve trended optic alignments, I’ve cleared ALS WFS histories, I’ve run the dither scripts, I’ve checked shutters for “open” and I’ve called Jenne. I left a message and haven’t heard back yet. Since microseism is still kind of high I don’t want to bother anyone who isn’t on call today until it gets a little better and the time gets a little later.

13:19 GRB alarm. Neither observatory is up.

13:24 PR3 was still in damped mode!!!!! GRRRR! I got my ALS spot back. :)

15:00 Finally got some semblance of an initial alignment happening.

SHIFT SUMMARY: After a harrowing night of wind and earthquake activity, Initial alignment is happening. Ground motion is still high. Handing off to Cheryl.

Apologies. My activity log doesn't reflect the eq activity between 09:08-10:00UTC. This gives the impression that I was switching GS13 gains because of wind.
