Ops Tusday Mid Shift Report

Acquired the IFO while it was in Manual Initial Alignment.
Had troubles with SRM in ACQUIRE_SRY . Touched SRM one last time and it locked just fine.
Started Locking, and ALSX & Y were way off.
Interveined and eventually Jenne said we should redo intial alignment with ITMs due to the ITM Camera Servo Error signals were large.

Initial_Alignment started Got to PRC_ALGNING and PRM was continuously saturating.
We then took ISC_LOCK to down and MANUAL_INITIAL_ALIGNMENT.
Worked through PREP_FOR_PRX and manually moved PRM to maximize Peaks and Valleys on H1:ASC-AS_DC_NSUM_OUT16.

Then moved through MICH_BRIGHT OFFLOADED and SR2 ALIGN manually.
I did have to move SRM again.
After this Locking happened quickly Starting at 00:55 UTC.
Reached NLN at 1:39 UTC and Observing at 2:03 UTC


Dust alarms in the optics labs are going off. Wind is only 15 mph.


Current IFO Status: NOMINAL_LOW_NOISE & OBSERVING.
