OPS Saturday EVE shift summary

TITLE: 11/02 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Microseism
INCOMING OPERATOR: Oli
SHIFT SUMMARY: The secondary microseism is at about the same level as the start of the shift but the wind is much lower. We have not been able to lock DRMI or PRMI for more than a few seconds this shift. The alignment keeps running away, we get stuck in a loop of PRMI to CHECK_MICH. I also adjusted the SQZ SHG_FIBR_REJ power while we we're trying to get DRMI.
LOG: No log.

After going into CHECK_MICH then back to PRMI it looks worse
