• The duty cycle was 95.6% on Monday, 36.0% on Tuesday and 27.9% on Wednesday, 53.2 in overall. The range was around 55 Mpc over three days.
• On Monday, the range was degrading slightly and had many dips while glitches appeared between 10Hz and 30Hz during before 10:00UTC, this is maybe because of the wind. Then, glitches in PCAL X showed up after the lockloss at 10:16UTC which is due to unknown cause. 
• On Tuesday, the lockloss occured at at 9:10UTC, then we had a trouble with OMC DCPD saturations after the lockloss. But we were mainly fighting against violin modes. 
• On Wednesday, we succeeded damping violin modes around 5:40UTC and went back to observing. RF45 glitches appeared around 10:00UTC. Then, we lost lock around 11:00UTC probably due to the earthquake for Japan and we had violin modes again. 
• Apart from that, we had GRB alerts at 00:50 UTC and 13:03UTC on Monday, 05:59UTC on Wednesday.
