A2L measurement showed elevated in Yaw, so ran A2L.

4.7kHz was damped at the beginning of the lock last night with 0deg (MODE10 outmon went down to +/-2000counts on strip tool).  But saw that the resonance was rung up again.  So, I tried +30deg & this quickly rung up the resonance.  I then added -60deg (for net -30deg) & this took damped out the resonance within minutes (& took the MODE10 outmon to +/-10 counts).

Summary of 10min out of Observing:

• 0:30utc  L1 Down, dropped out of OBSERVING
  • 0:30 - 0:38 Ran A2L (because was out in yaw)
  • 0:38 - 0:41 Damped 4.7kHz resonance by ENABLING FM9 [+30deg] (which rung up within seconds) & then ALSO ENABLING FM6 [-60deg] which damped out in within a couple minutes.
• 0:40 H1 Back to OBSERVING
