TITLE: 05/02 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 159Mpc
INCOMING OPERATOR: Oli
SHIFT SUMMARY: Robert replaced all the view-ports, so the LVEA is ready to be transitioned back to SAFE whenever. We broke back into the 160s today, we briefly hit 161.8 Mpcs. Johnson Controls finished and headed out around 21:10UTC.
Lock#1
17:52UTC Lost lock right before 11.5 hours, possibly from a jack being used in the optics/pcal lab
Lock#2
No good flashes, went through CHECK_MICH. PRMI then locked pretty low but ASC was able to fix it
18:18 UTC VPW major dust alarm, 0 to 80k in a few seconds. It came down after 10-15 minutes
18:21UTC Lost lock after turning on BS_STAGE2 too early, from the alignment not being that great? The next attempt I held us in engage_drmi_asc for a few minutes before continuing.
4 SDF diffs I accepted, relating to SCRL FF and Y2LI accepted SDF diffs for Sheilas SCRL FF gain and Y2L measurements
Lock#3
We struggled to get past ENGAGE_DRMI_ASC, the BS was getting kicked (glitches?) mostly seen by the ST1 L4Cs and T240s
Relocking at MAX_POWER right now
