TITLE: 11/16 Day Shift: 1530-0030 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 157Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY:

IFO is in NLN and OBSERVING as of 22:35 UTC

There was one IMC-caused Lockloss which ended our 13hr and 36 min lock acquisition. (alog 81310)

Stayed locked for the majority of this shift with one somewhat troublesome lock acquisiton for a number of reasons:

• ALSX was stuck at 0.15 cts, with a max of 0.3 cts after intervension. I went into manual initial alignment to continue troubleshooting. Jenne advised to touch ITMX, which worked. I was able to get ALSX to the normal ~0.8cts and let guardian successfully take it from there. Initial alignment happened fully auto.
• We were able to lock up until OFFLOAD_DRMI_ASC until a lockloss occured due to the IMC glitch. The IMC was still coming in and out, locking and unlocking for 4 more minutes.
• We were able to get all the way up to LOWNOISE_ESD_ETMX, before losing lock again.
• IFO was able to lock to NLN on the third and final try.

I was not able to take a calibration measurement due to the Lockloss, and we're not thermalized yet. I've informed Tony, the EVE operator, and he will take a calibration sweep once thermalized (01:24 UTC).
