Ops Day Shift Start
TITLE: 01/15 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Aligning
OUTGOING OPERATOR: Ed
CURRENT ENVIRONMENT:
    Wind: 3mph Gusts, 1mph 5min avg
    Primary useism: 0.03 μm/s
    Secondary useism: 0.27 μm/s 
QUICK SUMMARY:

I could not log in to the alog earlier. This seems to be resolved now (see Dave's alog).

Ed was having trouble with initial alignment when I arrived and was on the phone with Keita. Ed told me that Keita sent a message to Sheila, Jenne and Kiwamu to ask for assistance. Sheila called me and I told her about the diag main message I was seeing: 'IM_ALIGNED: IM3 P is out of its nominal range of 1961'. I sent her a plot of the IM 1-4 witness sensor positions over the last 7 days. She suggested that I move IM3 P back to 1961 and retry initial alignment. I did so and am now on the initial alignment of the arms on green. The X arm locked easily, but I am not getting any signal for the Y arm. There is a spot on the camera, but it does not seem to move with the optics. I trended back and moved the positions of the ITM, TMS and ETM to no avail. I have just started looking for the dither align script.

Moved IM3P alignment offset from 29542 to 29864 to move the WIT P from 1945 to 1961.
