Monday OPS Day Shift Starting Report.

TITLE: 03/16 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
OUTGOING OPERATOR: None
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 6mph Gusts, 4mph 3min avg
    Primary useism: 0.03 μm/s
    Secondary useism: 0.30 μm/s 
QUICK SUMMARY:

Seems to me like it's a good day to Lock and IFO.
Beam splitter ISI had a wtchdog tripped when I came in.
There are a few things that seem a bit off with the ISI Like: the ISI_BS_ST1_SC Guardian is white like it can't load something. The CPS  blends have White boxes in them. FF01 & 12 , ST 1 & 2 ISO ,  all contain red boxes.
HWWD stat button is white. Spoke to CDS team Dave Said the ISI_CUST_CHAMBER_OVERVIEW screen needs to be updated to show the ISI_BS_ST1_SC Guardian correctly. As there may be an error on that screen.

Locking Notes:
Took ISC_LOCK to Manual_INTIAL_ALIGNMENT 
Aligning Green arms: 
X arm is only around 0.4 after my best attempts to align it. I may double the H1:ALS-C_TRX_A_LF_OUT16 value. to get past Locking IR.
Y arm however has fantastic flashes. 

Requested ALIGN_IFO to PRC_ALIGN_OFFLOADED & Got Stuck at WFS_CENTERING_PRX.... maybe we are't yet able to use the WFS? 

Took ALIGN_IFO back to init then PRX_ LOCKED, Made it there. then to Down, then to MICH_BRIGHT_OFFLOADED.
