    Day shift summary:

    shift workers: J. P. Chen (SL), R. Micahels (TO), A. Glamazdin (3rd)

    8:00 shift started with configuration change in progress:
    change from production tgo elastic 2.
    Left magnets ramping down. Already called for controlled access.
    Need to switch polarity to postive(Howard)
    HRSL needs to be set to 2.245 GeV, 36.3 degree.
    Calo needs to be moved to 24.3 degree, 5.5 m distance.
    Sasha will also go in to fill Moller magnet.
    9:10 Hall in Controlled access. Howard is in to change polarity.
    Sasha went in to fill Moller.

    11:00 Calorimeter moved, HRSL polarity reversed to +, moved 36.3 degree and set to 2.245 GeV. Moller filled.
    Requested back to beam permit.
    11:15 requested controlled access (Alex/Carlos) to fix problem with
    the calorimeter.
    12:15 Alexc/Carlos out. request for beam permit.
    12:25 askde for 5 uA (EMPTY target).
    12:30 Got 5 uA, BPM position good. Askde for harp scan.
    12:45 finished Harp, moved to LH2 15 cm. Asked for 2 uA.
    Started elastic 2a calibration. runs 7878/7879.

    14:46-14:55 changed to 2b condition: HRSL at 37.86 degree, 2.131 GeV.
    started elastic 2b calibration. runs 7880/7881.

    16:00 still taking data for elastic 2b (run 7881).

    run 7878 12:46-13:44, 2uA on 15 cm LH2, elastic 2a, HRSL+, 120K.
    run 7879 13:45-14:46, 2uA on 15 cm LH2, elastic 2a, HRSL+, 123K.

    run 7880 14:55-15:45, 2uA on 15 cm LH2, elastic 2b, HRSL+, 110K.
    run 7881 15:46- still running at the end of shift. elastic 2b.
