NOAA-17 Clock Error Corrections, October 30, 2003
==========================================

Instrument(s) Involved:
     All

Product(s) Involved/Affected:
     All products/Improved timing

Date/Time(UTC) of Initial Implementation:
    21 October 2003, Time 2359 UTC - daily ETCUP
    23 October 2003, Time 2359 UTC - one time clock adjustment

Details/Specifics of Change:
The original message sent out on October 20 announcing the NOAA-17 
daily ETCUP adjustment contained the wrong date for the implementation.  
The daily ETCUP  adjustment of approximately -1.6 ms was begun on 
October 21, 2003.  In addition, the NOAA-17 spacecraft clock update 
was performed on  October 23, at 2359 UTC, on orbit 6016.  A -50 ms 
clock correction was applied to reduce the clock error.

We apologize for the lateness of this notice and hope that it did not create 
a problem for you.
