Good first half of the shift. The IFO has been locked for the past 15.75 hours,and continuously Observing for 9 hours. Winds are light and the microseism has been declining over the past 2 hours. There were several mid-sized (mag4.5 to 5.5) earthquakes in and around the Pacific that rung up the microseism. They were not powerful enough to cause any difficulties.
