TITLE: 06/28 Eve Shift: 2330-0500 UTC (1630-2200 PST), all times posted in UTC
STATE of H1: Lock Acquisition
INCOMING OPERATOR: Ryan S
SHIFT SUMMARY:

IFO is in ACQUIRE_DRMI_1F and LOCKING

Overall a very calm shift in which we were locked for the majority of it until the ETM glitch (lockloss alog 85402) killed the 8 hour lock.

Relocking was time consuming since the alignment was terrible and we have the 30 min wait before we can do an initial alignment. After I ran a fully auto inital alignment, locking went quickly until we lost lock at LOWNOISE_ASC (522). This also happened yesterday. Just like yesterday, the wind was hovering around 25mph with the primary microseism on the rise. Just like yesterday, there was an earthquake coming through. While I think we could have rode the EQ out and that the wind conditions weren't too bad, I believe that either this state might be a tad more susceptible to such noise or there's a controls issue. (or the same thing happened twice in the same way and will only happen twice). I will investigate tomorrow during shift.

Either way, we lost lock from DRMI but flashes looked good and I think (knock on SSTL) guardian will be able to get into OBSERVING on its own.

On the bright side, we rode through a 6.1 EQ from the phillippines though I did intervene to turn EQ mode on manually since the bulk of the ground motion was starting but the automation hadn't turned it on yet (judging from how much the ISC had to move to keep IFO still).
