TITLE: 05/04 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Aligning
INCOMING OPERATOR: Patrick
SHIFT SUMMARY:

H1 never recovered after the near 42 hour lock. There's something amiss with the Y arm alignment. Keita and I have been on the phone for ~4 hours trying to do things remotely before deciding to come out to the site.

LOG:

17:00 Started initial alignment. Y arm alignment was way out

16:17 GRB alert - LLO contacted H1 still in alignment

16:23 Y arm locked but at the expense of ITMY - trying to correct

16:43 Dither Align TMSY

16:58 Y arm locked once again. Better but may take some time to converge ITM YAW. - still no satisfaction

22:50 Been on the phone with Keita most of the day. Y arm locking has been weak to say the least. He is on his way in now.
