Hello All,

RE: Update on monthly changes of OIG/GSFC Satellite Situation Report

I decided to make a monthly report of significant changes found in
the OIG Satellite Situation Report (SSR) due the number of such items
found. OIG's report is based on TLEs received from USSPACECOM.  And
users without program routines to 'catch' such re-cataloged TLEs or
name changes may not be aware of them.


Nov/Oct    v40#11/v40#10  1 re-cataloged   2 variant name changes

Oct/Sept   v40#10/v40#9   4 re-cataloged   1 significant name change
Sept/Aug   v40#9/v40#8    5 re-cataloged   3 significant name changes
Aug/July   v40#8/v40#7    2 re-cataloged   O significant name changes
July/June  v40#7/v40#6   12 re-cataloged   2 significant name changes
June/May   v40#6/v40#5    O re-cataloged   O significant name changes

Re-cataloged objects are those which the launch ID number has been
assigned to a NORAD number designation _different_ than the original.
Significant name changes are defined as those clearly not same object.
In other cases, name is similar, but generally more precise in nature.

Please make requests for previous reports on this matter directly to
my email address shown below.
