TITLE: 02/19 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Commissioning
INCOMING OPERATOR: None
SHIFT SUMMARY:

Shorter Maintenance Day to allow for more Commissioning time.  After Maintenance, performed an Initial Alignment + looked over Jenne/Nutsinee's shoulders as a Squeezer alignment was also performed.  Made it to NLN, with the help of Kara M., but it dropped out shortly after--Sheila noted a ~4Hz oscillation on an ETM---believe she mentioned this being related to dither align.  Regardless, she had me hover at LOWNOISE_ESD_ETMX on the order of 15min to let our locking signals stabilize before moving to NLN.
