TITLE: 12/11 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
CURRENT ENVIRONMENT:
SEI_ENV state: USEISM
Wind: 52mph Gusts, 37mph 3min avg
Primary useism: 0.13 μm/s
Secondary useism: 0.61 μm/s
SHIFT SUMMARY:
We had Planned to lock today to get proof of life out of H1, but then...
The tumbleweeds were trying to get in from the Roof during the 70 MPH Wind conditions we had today. We let the tumbleweeds win and didn't try to lock but did other things.
Y arm was clear enough for TJ to get to, but X arm is impassable due to a tumble-anche along the road there.
Beckhoff Upgrades were done for Corner5.
Faroing was started but not finished.
JAC work has started and we were able to recover the IMC.
CDS was able to make some progress today as well.
Random notes I took throuout the day:
Dave did a restart everything here.
Frame writer restart happened today.
The Wind only Looks like it reached 114 MPH as indicated by the wind speed, but it only hit 70 MPH.
Corner 5 beckhoff install starting at 23:00 UTC
FW1 rerstart @ 23:05 UTC
Might need to reboot ASCSQZIFO or ASCSQZ0 computer: Completed.
PSL enclosure temps alarm sounded off at 23:22 UTC during the DAQ restarts.
440 channels added to H1EDC for beckhoff.
IMC recovery :
I ended up Clearing history on IMC WFS...
Reverted MC and IMC PZTs back to GPS time: 1449411452 (the last time we had the IMC locked.)
I then moved MC2 until the we had a good lock on MC_Trans. IMC-WFS_GAIN was taken from 0.04 to 0.4 and then back again to allow the WFS to move IMC.
We then offloaded it.
