TITLE: 10/26 [EVE Shift]: 23:00-07:00 UTC (16:00-00:00 PDT), all times posted in UTC
STATE Of H1: Lock acquisition
SHIFT SUMMARY: Initially had trouble locking DRMI. Went to LOCK_PRMI and aligned the BS. Jenne had put the ISI blends back to 45 mHz. Could this have moved the BS alignment? Successfully moved from LOCK_PRMI to LOCK_DRMI. No trouble locking DRMI since. Evan, Jenne and Sheila worked on ASC SOFT loop instability (see alog 22858). We made it to nominal low noise but loss lock while running the a2l script (see alog 22860). Second lock at nominal low noise was lost after trouble with the ISS second loop.

Still having trouble with ASC loops and also with the ISS second loop. Jenne and I called Kiwamu about the ISS second loop and he decided he will drive in. Also contacted Mike. We have permission to call off the second half of the owl shift if no progress is made.
