    Significant Events
    16:00     
    Shift begins with produciton running underway.
    16:15
    Cage temp alarm went off.  Seems to be stabilizing.  It is quite warm in the outside world.  For now we will monitor it.
    21:06 IOCSE20 died.  This was detected by the IOCSE20-freeze alarm created by Paul. Note that the beam also died at roughly the same time. Current run (21425) ended.
    21:20 IOCSE20 died again.  Reboot. Current run (21426) ended.
    23:14 IOCSE20 died again.  Reboot. Current run (21428) ended.
    We had very good beam during this shift.  There was a period of 62 min with no beam trips.  Parity quality seems very good too.
