TITLE: 02/22 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC
STATE of H1: Observing at 120Mpc
INCOMING OPERATOR: Ed
SHIFT SUMMARY:

I was told by Cheryl that we are keeping INJ_TRANS set to INJECT_KILL for the indefinite future due to the possibility of a supernova.

There was one lock loss from observing.

I ran across a user code error in CHECK_MICH_FRINGES. I think I may have fixed it, but CHECK_MICH_FRINGES did not leave the alignment in a good state for ACQUIRE_PRMI. We lost lock at ACQUIRE_PRMI twice before I ran an initial alignment. The initial alignment seemed to fix the issue.

Currently riding through a series of earthquakes in Chile with SEI_CONF in EARTH_QUAKE mode.

20:01 UTC Lock loss
20:29 UTC Lock loss from MOVE_SPOTS
