    0:00 Shift starts noticed jumped in beam position 1:05 L. Richardson that two feedback were interfering, after turning the lock off beam position is good. http://opweb.acc.jlab.org/CSUEApps/elog02/elog_item.php?elog_id=1369714

    2:45 Beam position shifted by 1mm, asked to correct it, not sure what happened...

    2:48 Q1 trip at end run 2351

    2:52 Q1 back run 2352

    5:54 Q1 tripped run 2360

    Many trips and odd oscillation of the position after a trip.
