TITLE: 11/15 Eve Shift: 00:00-08:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Travis
SHIFT SUMMARY:

A bit of a rough shift with H1 making it to NLN, but only staying locked on the order of ~25min.  Observe ASC signals growing (over a period of 4-5min) just before it breaks out of lock.

LOG:

• 3:58 Undisturbed
• 4:10 Changed Gain for Mode28 (Terra)
• 4:44 Undisturbed
• 6:25 Had an "ETMX RMS WD has tripped" Verbal Alarm.  Used this alog to "untrip".

Notes:

• After most locklosses:  (1) HAM6 ISI trips.  (2) ITMy swings up to 20min before ALS locking can continue (tried damping via the Oplev Pitch damping, but didn't notice an improvement).
• Lately, the IMC has been breaking lock at various points.
• (3) Cal Lines Are Off:  PCALy, CAL-CS_DARM, & ETMY_L3
• If we make it to NLN, Kissel would like (2) Calibration measurements run (he has notes on a notepad)
• Terra has (4) Modes we should damp:  3, 26, 27, & 28.  If we are in Undisturbed/Observing and need to damp one of these modes, we should note the time & the changes we made.
• Mode9 was noticed as a possibly new resonance to damp.  If it starts to ring up, just put in a gain of 1000 or so and then work on it from there.
