Wednesday Morning Ops shift report

TITLE: 03/19 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Observing at 145Mpc
OUTGOING OPERATOR: Oli
CURRENT ENVIRONMENT:
    SEI_ENV state: CALM
    Wind: 5mph Gusts, 3mph 3min avg
    Primary useism: 0.02 μm/s
    Secondary useism: 0.24 μm/s
QUICK SUMMARY:

H1 has been locked and Observing for 6 and a half hours.

Looks like H1 was relocked via the H1 Manager Guardian at 08:09 UTC this morning.
We went through locking ALS5 times, until H1 Manager went through an initial alignment, which allowed a quick relock after that.  
All systems seem to be functioning.

I thought that perhaps the Lockloss last night was cause by the Earthquake, but that earthquake struck while H1 was relocking and was not the cause of the lockloss.
Currently the Lockloss is unknown. LL pics attached.
