    Comments: 5:20 We asked for the beam to be turned off (tour in the hall). Bodo and Bob Micheal took the chance to access the detector. Jian-Ping worked on the laser alignment. 20:50 Beam is restored 10:45 A cavity keeps tripping -> beam is turned off to fix the problem. 23:20. Beam is back (problem desapeared). 24:00. Asked for beam 1/2 wave plate to be put in (we are done with the data taking on c12, toggle mode, beam 1/2 wave plate out: about 26 M event)
