Based on recommendations from Jess McIver, a full report based on the following summary can be found here- https://wiki.ligo.org/DetChar/DataQuality/DQShiftLHO20170622

Thursday the 22nd
		○ Knocked out of lock overnight by earthquake in Guatemala, regained it around 15:50 UTC. Microseism at 0.03-0.1 Hz reached 10 um/s, 0.1-0.3 Hz reached ~1 um/s.
		○ Also had reasonable high winds over night, in the ~25 MPH range.
		○ Used most of the morning for signal injections since LLO was down.
		○ Right around 20:17 UTC, noticed cross-frequency glitch, across 100-800 Hz, which rung up and then down within about 1 minute. Since other fellows hadn’t seen this, we investigated a little more. A SUS MC2 damping channel had coupling with a bunch of other subsystems and channels inside the OSB but they don’t correspond to any seismic peaks so I’ll need some DetChar help if we want to analyze further.

Friday the 23rd
		○ Some small range drops overnight due to overflows but morning was quiet otherwise.
		○ Mid day, we had an event alarm (G250171 in GraceDB) but it turned out to have a high false alarm rate.
		○ Except for a few overflows, we were steady throughout the day. HVeto did show another seismometer/accelerometer blend channel as the winner for the day, though, which was again coupling to a ton of other seismic isolation and stability control channels and without clear microseismic disturbances.

Saturday the 24th
		○ Some small range drops overnight due to overflows and “small earthquakes” (according to Alogs).
		○ Saw more cross-frequency glitches at 16:13 UTC and 16:50 UTC, which were across 10-1000 Hz, but they were single points and the earlier one seemed to correspond to spikes in Z-axis microseism. I didn't determine a clear cause for the later one.
		○ Quiet shift otherwise.

Sunday the 25th
		○ Range was all over the place today.
		○ Lost lock twice overnight. Operator didn’t report a clear cause in the Alogs and the PEM channels didn’t show any smoking guns.
		○ An earthquake in the South Pacific knocked us out of lock again mid-day, and instability knocked us out of lock two more times later in the day.
