Title: 10/20 Day Shift 15:00-23:00 UTC (8:00-16:00 PST). All times in UTC.
State of H1: Aligning
Shift Summary: H1 was down when I arrived this morning due to power outage. After extensive recovery and some minimal maintenance day activities sprinkled in, I began initial alignment. After a couple of hours of diagnosing why we weren't able to see the ALS beam, Keita discovered that the ISCT1 shutter was closed. At about the same time, we got hammered by a 7.1 EQ in Vanuatu ringing up both the 0.03-0.1 Hz and 0.1-0.3 Hz bands to over 1 um/s. Waiting for these to ring down.
