    16:00 beam centering
    16:40 beam centered,
    16:45 start dilution runs
    17:00 set left arm for PF runs
    17:54 left arm set to production running, 3rd arm DAQ SLOW
    access to the hall for a reset.
    18:50 start production, without 3rd arm
    20:00 completed p = 1.119 switch to p = 1.041
    20:00 Hall access to fix 3rd arm problem
    20:34 Hall closed ask for beam
    20:45 start production at new setting
    21:30 the students noticed that the current in the right septum was off (affected 22903 and the previous right arm run). Was corrected new run number: 22904)
    22:40 completed p = 1.041 settings production runs. Start dilution runs
    23:05 asked MCC for bleed through, reported 0%.
    23:10 completed dilution runs for p = 1.041 switch to p = 0.968
    23:43 completed dilution runs for p = 0.968 right arm was still changing slightrly ( 1- 2 MeV/c).
