*Details/Specifics of Change:*

On 9 July 2007 around 1730 UTC, operations accidentally implemented a 
bad User Ephemeris File (UEF) of orbit parameters for NOAA-16 .  This 
was used to produce bad earth locations in the level 1b data for the 5 
files listed below.  Each pass was reprocessed and distributed to users.

On 10 July 2007 Around 0100 UTC, the UEF was corrupted again with the 
same bad data.  This problem was not detected until around 1130 UTC.  We 
have updated the UEF and reprocessed the affected 1B data as indicated 
below.
