    16:00 Still waiting for beam
    16:45 Beam returns. Begin Moller measurement.
    17:55 Problems with beam. Pulsed beam.
    18:09 CW beam.
    18:35 Moller finished. Asked MCC to change bpm survey offsets to:
    ax=-1.899 ay=-2.627
    bx=-0.848 by=-1.407
    19:07 BPM survey values now set.

    Run #3038 - Cosmics
    Run #3039 - JUNK

    HARP scans to study beam positions
    Run #3040 - HARP #958 bpm x=0, y=0
    Run #3041 - HARP #959 bpm x=-1, y=-1
    Run #3042, 3043 - JUNK
    Run #3044 - HARP #960 bpm x=-1, y=+1
    HARP #961 bpm x=+1, y=+1
    Run #3045 - HARP #962 bpm x=+1, y=-1, maybe not good.

    19:55 Asked to go back to bpm x=0, y=0. RF trip.
    21:03 Beam back.

    Thcm 90 degrees pointing:
    21:04 Run #3046 - carbon target, 5uA, raster off
    21:12 Run #3047 - 4cm dummy
    21:19 Run #3048 - 15cm dummy

    21:21 More RF problems.

    21:54 Run #3049 - 10cm dummy

    Beginning production point thcm=90.
    Including aerogel in trigger.
    22:06 Run #3050 - trigger efficiency check

    6msr collimator runs:
    22:14 Run #3051 - 47uA.
    Run ended due to 100% deadtime. End run failed. Kcoda.
    22:25 Run #3052
    (all runs previous to this, at this setting,
    have the wrong hadron angle in start of run)

    open collimator runs:
    22:58 Run #3053 1.3M events
    23:15 Run #3054 1.3M events
    23:35 Run #3055 1.3M events
