QUICK SUMMARY:
Lockloss at 8:09 UTC
Started the relocking process without an initial alignment.
Reached CHECK_VIOLINS_BEFORE_POWER UP at 846 UTC
I then held there and turned on the Damping at 2Ws for about 2-3 minutes.
I then started the powerup process while Elenna and Rahul were watching the Violins.
They started to se a few modes increase during power up around 25W. I then finnally turned off the Damping at 2W.
9:19 UTC We reached OMC_WHITENING.
We Divided the VIOLIN DAMPING amongst our selves and started to carefully increase gains incrementally to their maximums.
The DARM looked very bad during the entire duration of OMC whitening due to what Elenna describes as jitter.
9:58 UTC NOMINAL_LOW_NOISE was reached. I think this is a fairly quick transition though OMC_WHITENING.
H1: LSC-MICHFF SDF Diff was accepted get into observing.
10:03 Observing was reached again.
Nothing Interesting happened since we got back to observing.
Current IFO Status: Locked in NOMINAL_LOW_NOISE & OBSERVING for 5 hours with range of 130 Mpc.
