TITLE:    Dec 21 EVE Shift 00:00-08:00UTC (16:00-00:00 PDT), all times posted in UTC

STATE Of H1: Observing @ 80Mpc

SUPPORT: N/A

INCOMING OPERATOR: Jeff B

 

SHIFT SUMMARY: Lots of trouble with µSei and a bit of wind that blew up. The details are in the activity log. ISI Blends set to 45Mhz around the board except for ETMX off axis

ACTIVITY LOG:

01:15 Trouble with input align. PR2 pointing was bad. Yaw was off by 6µrads

01:18 Dark mitch still won’t grab. µSei is now peaking around 1.5µm/s. Wind is still NOT an issue. The beam splitter appears to be really feeling the ground motion.

02:50 Touched base with Jenne just to apprise her of the IFO situation

03:00  took ISC_LOCK to down. There doesn’t seem to be any locking (ie Dark Mich, PRMI or DRMI) going on in my near future. uSeism is still trending above 1um/s and the BS is jumping all over itself. th wind has also blown up to >= 20mph at EY.

05:58 PRMI locked! (first small victory)

06:01 DRMI Split mode. no time to tweak.

06:08 DRMI Split mode. no time to tweak.

06:14 DRMI Split mode. no time to tweak.

06:24 Lockloss. IMC broke lock.

06:57 DRMI LOCKED!!!!

07:05  John called to tell me that he was turning on some heat in the LVEA. (H1CA)

07:13  Lost lock at COIL_DRIVERS. grrrrr

08:02 NLN!
