    12:00 Continuing tuning, optics target in place

    12:50 Raster check, trying to calibrate spot++/MCC values
    (error on the measurments are +/- 0.2 mm)
    2x2 MCC 2.29 x 2.29 Delta-x = 1.3 mm Delta_y = 2.3 mm
    3x3 MCC 3.43 x 3.43 Delta-x = 1.6 mm Delta_y = 2.9 mm
    4x4 MCC 4.74 x 4.74 Delta-x = 1.8 mm Delta-y = 3.3 mm
    10x5 MCC 11,93 x 5.88 Delta-x = 4.0 mm Delta-y = 4.0 mm

    01:35 Moving the right spectrometer to 60 degres

    02:10 The spectrometer is in place, waiting for the momentum to
    stabilize, adjusting Hvs, raster size 5x2.5

    03:30 Start production data on Helium

    03:55 Moving to lead target

    05:20 moving to carbon target

    05:55 moving to iron target

    07:00 moving to helium target, changing to Pr = 0.98952 GeV/c

    07:40 The dipole is still stabilizing

    07:53 Start data taking on helium at the new momentum setting
