    Dear colleagues

    FIRMWARE 
    The firmware for our Ashtech Z-12 receiver has been upgraded from CB00
    to CD00. The receiver was taken down at 1999 August 20 00:00 and
    restarted at about 01:30.

    LOG FILE
    An updated logfile has been submitted to IGS.

    POWER OUTAGE
    A gap in the data from 1999 August 20 1945 to midnight was caused by a
    power outage at the site.

    EXTERNAL FREQUENCY
    The external 10 MHz frequency supplied to the receiver drifted slightly
    during the interval 1999 August 20 00:00 and August 21 12:00 but has
    been stable since.

    Regards
    Roger Wood
