    Spectrometer momentum change on the right arm to 186.992 MeV/c
    Move target to F56

    04:41-05:02 Run # 2250 (left ) events 476K
    Right arm momentum still settling

    Ignore run # 20719 wrong info it is Iron target. The run
    is very short since the deadtime wasn't properly checked.

    05:08-05:32 Run # 2251 (left) events 562K
    Run # 20720 (right) events 450K
    (started data when Momentum was
    about < 2 x10^-3 of the set point.)

    Moved the target to 12C right

    The number of trips during the above run was high.

    Started a new run on the same target hoping for a more stable beam.
