Data was good throughout the four days.  Hyperlinks are behaving strangely for me in the html editor so here's the URL of the shift report:

Overall Summary:

- Duty cycle of 82.2% for the four days.
- First two days were hit with many EQs and aftershocks. Our duty cycle was actually pretty good considering how many spikes there are on the summary page's seismic BLRMS plots, but they did cause some locklosses.
- Work was done to damp PI modes at times and they were noted in the aLogs but they were not blamed for any locklosses.
- Evening of the 24th some opportunistic commissioning was done.
- PSL tripped at 8:38 on the 25th. Expert was needed to get things working and were out of Observing for a little more than 3 hours.
- Interesting 3.5M EQ from central Washington on Sunday the 26th knocked us out of lock but did not show up in the normal EQ band seismic noise plots. Instead, large spikes showed up in all of the higher frequency ground motion plots (> .3 Hz).
