TITLE: 10/01 Day Shift: 15:00-23:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 153Mpc
INCOMING OPERATOR: Tony
SHIFT SUMMARY:
One lockloss today, and also addressing violins (see Rahul's alog)---the latter looks better.
LOG:
- 1635 Lockloss
- Green Arms and DRMI alignment looked good for locking.
- Locklosses at LOCKING ALS, SHUTTER ALS
- Needed to help FIND IR on 3rd locking attempt
- Took ITMy Mode-5 gain to -0.02 (from nominal of -0.04) to help with damping down violins.
- 1745 back to Observing
- 1821 Rebooted the camera/access system computer (it had frozen)
- 1955 I lowered itmy mode 5 gain & contacted Rahul
- 2009 Rahul starts working on ITMy
- 2038 Gain changes were not helping ITMy, so this is when Rahul made a phase change (Rahul thought a phase change would bump us out of Observing, but it did not.)
