LOG:

23:00 UTC Relocking
23:13 UTC Chandra to mid Y
23:28 UTC Restarted video0
23:29 UTC Restarted video3
23:45 UTC Started adjusting ALS fiber polarization
23:59 UTC Chandra and Kyle done running scroll pump at mid Y (alog 47944)
00:02 UTC Done adjusting ALS fiber polarization. Could not get the X arm ALS fiber polarization error less than 15%. It is odd that it could go to greater than 100%.
00:34 UTC Jeff K. discovered that the ETMX L2 LEN to YAW filters had a gain of +1, should have been -1. Explains previous two locklosses from LOWNOISE_ESD_ETMX. Jeff K. fixed.
01:03 UTC NLN. Accepted SDF differences from adjusting ALS fiber polarization. (alog 47947)
01:09 UTC Set observatory mode to calibration.
01:22 UTC Lock loss. 4.2 Hz ASC oscillation. (alog 47949)
01:30 UTC Starting initial alignment
01:54 UTC ITMY camera has died
01:56 UTC Powercycled h1digivideo2. Everything back except h1cam23.
02:04 UTC Realized I forgot to set observatory mode to aligning. Did so.
02:42 UTC Initial alignment done. Had to intervene for SRM.
03:24 UTC NLN
04:07 UTC Observing (alog 47957)
05:03 UTC Dropped out of observing by TCS ITMY CO2 guardian. Seemed to recover itself. Went back to observing.
06:16 UTC Started Jenne's IMC VCO sweep script (alog 47954)
06:24 UTC Reloaded INJ_TRANS guardian per Adam's request (alog 47942, 47943)
