23:07 Detector trying to relock and failing

23:35 I put the detector into Down for 20 minutes to wait for the wind to die down

23:56 Trying to lock again
    - 00:27:46 Eventually got to CARM_150_PICOMETERS before losing lock
    - 00:47:21 Lockloss at ENGAGE_ASC_FOR_FULL_IFO

1:00 Starting Initial Alignment (accidentally started with H1_MANAGER off, so I left it off for this)
    - Was able to get through to SRC_ALIGN_OFFLOADED!!, but INIT_ALIGN was stuck at ALIGNING_INPUT (71669).
    - Reenabled H1_MANAGER (although I had issues with getting it to recapture ISC_LOCK) and let it run alignment (on its terms) and everything went smoothly

3:31 Reached OMC_WHITENING

3:40 Arrived at NOMINAL_LOW_NOISE, needed to wait for ASC-ADSs to lower

3:55 Finally back into Observing!

5:40:50 Lost lock immediately after being pushed out of Observing (71673)

6:38 Entered OMC_WHITENING

6:52 Entered NOMINAL_LOW_NOISE

6:56 Back to Observing
