TITLE: 05/26 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Corrective Maintenance
SHIFT SUMMARY: Today has been busy with recovery efforts for H1. The day started with touching up alignments to get DRMI locked again with some stability, although buildups didn't look as good as they have in the past. We discovered that we could not switch to the POP PD used for DRMI 3F without losing lock, which prompted a more thourough investigation into potential chamber motion (see alog 69924 for more information). After restarting models for HAMs 2, 3, 4, 5, and 7, restoring alignment for PR3, and relocking green arms, Shiela and TJ are off to realign and recover the ALS beatnotes on ISCT1. Please see other alogs from today (some to-be-written) for more detail.
