As soon as L1 locked up, H1 nosedived with a huge noise source at 25.37Hz (big ugly peak with sidebands) & its harmonics (Sheila could not find a SUS resonance at this frequency).  This dropped sensitivity from 60Mpc to 30Mpc.  After about 15min, I intentionally broke lock to see if a new lock would improve sensitivity.  (Note:  It wasn't clear to me how to break lock with our new fandangled aLIGO H1 detector.  I hit DOWN in the ISC Lock Guardian Node, but this just made the whole node fault RED.  Ultimately, I went to the LSC Overview & pushed the OFF button for LSC Mode & that did the trick.

I wanted to quickly go back up, so I saw the Yarm was a bit ugly, so I tweaked on ETMy, but could only get up to 0.86counts (I thought WFS would kick in to get me over 1.0).  ISC_LockGuardian spouted off about "waiting for arms to lock" and never progressed with locking.  At this point, I went to the phone, and got a hold of Sheila.  She mentioned I could tweak TMSy, but I might do better to do a full Initial Alignment.  I ended up trying both.

Alignment was fairly straightforward (this was really only my 4-5th time to go through and alignment, AND I've never sat at the chair and had H1 lock by my own powers!).

• Green Arm alignment, I did tweak PR3 (took ALS RFMon from 3.9 up to 5.0). 
• PRM:  ASAIR was at a fuzzy 200
• Dark Michelson:  First attempt sent beams into la la land.  2nd attempt gave a dark fringe (but Align_IFO node was Orange & never thought I was on a dark fringe).  I tweaked on the BS a little (it was already fairly close.

Then I went for locking.  First attempt, I waited about 3-4min for DRMI to lock, but it dropped out during the "Switch to qpds".  Second attempt had me wait a whopping 3min for DRMI to lock.  And for this, lock I went all the way up to LSC_FF (Bounce modes were nice and well below 10^-12).

Once all the way through, I wasn't completely clear on what I had to do with the ETMx ESD Driver.  ESD ACTIVE was RED, but the monitors were all a few hundred counts negative (range was about 55Mpc).  So, I clicked on the "HI" button, which made ESD ACTIVE go GREEN briefly and then back to RED, and this sent the monitors close to zero (and range went up to 62Mpc).

SDF looked all GREEN, and Intent Bit set to Undisturbed at 3:58am (10:58utc), and H1 joined L1.
