Mostly uneventful night except for a random lockloss, which took the usual 1.5hrs to recover from.

Time to get our Maintenance Day on!
LOG:

• 12:47 Sudden lockloss in very quiet environmental conditions.
  • Lockloss Tool Notes:
    • ETMx L1 glitches 0.1sec before lockloss
    • Several ASC Control Signals (Arm) HARD/SOFT signals glitch about 0.1sec before lockloss
  • 1-5th locklosses were all over the place!  (beginning to think H1 really just needs the time to humor us and cool down before it's ready to lock again)

• 13:30 - 14:12 Noticed some small EQ activity, but nothing on SEISMON or USGS.
