    Continuation of running at Theta_CM = 135, Phi_CM = 0
    .

    Run 1648 ... 1.25M events, checked spot .... looked OK

    Approximately 27M events this shift at this kinematics. Total duration from
    08:00 to 13:10 at a steady 50 uA (approx. 0.93 C of accumulated charge)
    .
    Pointing runs at Theta_CM = 135, Phi_CM = 0:
    Run 1655 ... 1.27M events, 10 cm dummy target
    Run 1656 ... 1.27M events, 15 cm dummy target
    Run 1657 ... 1.25M events, 4 cm dummy target
    Run 1658 ... 1.0M events, carbon target
    Run 1659 ... HARP run 922.data
    .
    At approx. 14:00 ....
    Changed HRSh angle to 53.635 deg, NO change in momentum (P_0=0.8188)
    for kinematics at Theta_CM = 135, Phi_CM = 180. This was done while Joe M.
    makes an ep measurement. The result of the ep measurement is 4.5320 +/- 0.0005
    (preliminary). Previous measurement (5/22) was 4.5313. Nominal energy is
    4.435 MeV.
    .
    Pointing runs ar Theta_CM = 135, Phi_CM = 180:
    Run 1660 ... 1.0M events, carbon target
    Run 1661 ... 1.1M events, 4 cm dummy target
    Run 1662 ... 1.0M events, 15 cm dummy target
    Run 1663 ... aborted due to anomalously high dead time
    .
    New crew here. I bid all a good nght.
