TITLE: 02/15 Eve Shift: 0030-0600 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Locking
INCOMING OPERATOR: Corey
SHIFT SUMMARY:

IFO is in NLN and OBSERVING as of 04:16 UTC.

EDIT: IFO is LOCKING at SDF_REVERT after a 05:59 UTC Lockloss

Overall calm shift with one lockloss due to an Earthquake (alog 82821).

Other:

• We also survived another earthquake (4.9 from W Texas).
• Range is quite low due to bad high frequency squeezing, which I was told to expect. This will probably remain the case until more table work is done next week.
• I tried (from Sheila and Ryan S's recommendation) a small test to see if going into GREEN_ARMS_MANUAL, locking the arms manually, then going through in INITIAL_ALIGNMENT_OFFLOADED would bypass our ALS locking failures. Interestingly, this worked, allowing us to lock with normal locking without running into ALS problems - the investigation continues.
• Ryan's new FM 1,3,10 -1G EY Violin Mode 20 seems to have worked, reaching a pre-LL minimum of 0.18 before nouncing about that. As such after the reacquisition, I re-set those as the EY20 settings.
