    8:00 day shift begins. Right arm still ramping


    11:00 Machine seems to have trouble trouble delivering beam to Hall A. MCC people are trying to find what the problem is.

    11:40 Beam is back but MCC still has problems with the controls

    12:01 MCC want to send tune beam in Hall. Stopping run
    4854 at 97k events.

    12:10 Turned regulator on right arm

    12:14 4 uA in hall starting run even though MCC has not called to tell tune was done.
    Run 4855 has unstable beam

    12:55 Called MCC to have an update, they are still working on their problems but beam seems stable enough to take data.


    13:13 Two arm run

    13:23 Moved to optics target : optics run

    13:32 Moved back to 15 cm LD2

    13:34 Bleedthrough 0.32 %

    13:45 Hall B ask for 10 minutes of Hall A and C off to calibrate their tagger. I accepted as long as it does not go over 10 minutes.


    14:13 Beam off for Hall B

    14:44 Beam ready to come back (it took more than 10 minutes...)


    15:51 MCC called Hall B is complaining about the beam quality
    MCC will investigate they estimate it to about 30 minutes without beam when they start.
