    00:17am start cosmic run 2328
    00:54am NMR measurement
    01:00am EPR measurement
    01:20am MCC phoned about sending tuned beam to hall A. Stop cosmic data taking.
    01:30am 25MicroA beam with raster on , pseudorandom made@BeO target
    run2331/21331 parity daq tripped
    run2332/21332-----2346/21346 have lot of junks.
    left arm DAQ problem : dead time--100%
    right arm is ok, dead time--16%
    05:10am Bob comes to fix the problem with right arm.
    run2347/21347 both arms are ok now.
    run 2347/21347 -run 2350/21350 are good runs.

    07:35am NMR 48.97%
    07:55am EPR 47.4%
    Finish data taking for flase asymmetry
    Right/left arm central momentum changed from 1.32GeV/c to 1.72GeV/c.
    beam half waveplate moved in, with helicity@toggle mode.
    Target holding field rotated to 270 degree.

    Ready for polarized He3 data taking, x=0.48 transverse.
