STATE of H1: Initial Alignment

INCOMING OPERATOR: Cheryl

SHIFT SUMMARY: EQ lockloss from Observing, followed by a wind gust lockloss from Observing. Acquiring lock was having the same issues each time so decided to try and align the optics to their positions in the previous lock. Running initial alignment now.

LOG:

15:00 (08:00) Start of shift

16:06 (09:06) Going to EQ mode for 6.7 near Tonga

17:41 (10:41) Lockloss from ENGAGE_SOFT_LOOPS. Looks like maybe a glitch.

20:19 (13:19) Lockloss, from a 40 mph gust of wind.

20:50 (13:50) Lockloss from ENGAGE_ASC_FOR_FULL_IFO, seems like another gust of wind.

20:51 (13:51) Running initial alignment, since I could barely get DRMI buildups above 50 last lock.
