TITLE: 04/24 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ed
SHIFT SUMMARY:
Notes:  Seismically quiet.  Porcupine spotted around the OSB nibbling on the bushes (photos attached).

Georgia made a Guardian change requiring a couple of LOADs for a couple of nodes at the next lockloss (& when Guardian is not actively logging through states---i.e. it has a green box).  See her alog.

Overflows for H1SQZ & H1OAF prior when locking (Sheila  cleared these earlier).

ALSx Polarization > 25% DIAG_MAIN notifications flashing on/off most of the night (as it has most of the week).
LOG:

• 23:00 Locking H1
• 23:07 Kyle back from mid-stations
• 23:20 - 0:02 Starting alignment
  • Green Arms:   ALS WFS DOF 3 was pretty slow to converge for both X & Y's pitch and yaw (with X-arm taking longer).  Gave it about 10min, but Could have waited longer.
• 0:02 Locking 
  • Had one DRMI lock which lasted a few seconds and dropped...but it did not go all the way DOWN & stayed at ACQUIRE_DRMI_1F (not sure I've seen that).
  • Next DRMI lock, stayed at OFFLOAD_DRMI_ASC to touch up PRM (mostly) & SRM alignment to get POP18 maximized (above 60).
  • Had a notification about "needing to find carrier by hand" for the OMC.  So, I took OMC_LOCK node to DOWN (which takes seconds) & then selected READY_FOR_HAND_OFF (this did the trick so we could continue with ISC_LOCK).
• 1:09 OBSERVING
• 2:39 - 3:39 GRB Stand Down period (possibly GCN #24166)
• 7:15 Handed off to Ed and H1 is going on 6hrs 5min of OBSERVING
