    16:03 end run 4154, change of half wave plate.
    16:07 start run 4155
    16:39 end run due to bad charge asymmetry
    16:39 start run 4156
    17:15 charge asymmetry erratic again
    17:20 talked to Hall C, they changed the PC voltage which weas probably the source. They are finished with it. Start a new run
    17:24 start run 4157, Happex 7465, Compton 13502
    18:30 end run 4157, start run 4158
    19:45 end run 4158, carry out NMR measurement (end 20:02)
    20:02 start run 4159
    21:11 end run 4159, no beam, MCC, magnet power supply trip
    21:24 start new run 4160, Happex 7466, Compton 13504
    after 22:00 beam studies and beam energy modulation in Hall C
    FB off, beam position OK
    22:33 end run 4160 start run 4161
    23:43 end run 4161 start run 4162, Compton 13505
