Started my shift with the IFO locked at NLN for the first ~2.5 hours.  After an EQ knocked us out, this was followed by another ~1.5 hour lock.  This was lost due to commissioning efforts.  Since then, we have been struggling a bit to get past ENGAGE_ASC.  There have been several largish spikes (~1 um/s) in the 0.03-0.1 Hz seismic plot, but only at EY.  Winds are gusting to 30 mph and microseism is trending down.  Evan and I aren't sure what could be causing these spikes, maybe it is wind.  The spikes seem larger than I am used to seeing for winds in this range.
