    keyword=Q1-Left Arm

    Left arm Q1 failed at around 13:55 due to low He level. Q1 power supply fault
    display listed He level faults #1 and #2, a ground fault and a PreReg fault (is
    that a preregulator?). The He level recovered by itself within about 10 minutes.
    Attempts to reset the supply cleared the first 3 faults but not the PreReg fault.
    Scot Spiegel is here and will go into the hall to clear the fault.
