    keyword=Shift summary

    8:00: Waiting for (good) beam;
    11:00: Right arm NMR blank, fixed around noon;

    13:35 run 1044 has too large spot size in Y (120um);
    14:20 start aperture scan;
    15:00-15:10 beam trip;

    When taking aperture runs the beam position FB was off from time to time. MCC said they are still working on it.
