      It was STSS Demonstrator rather than STSS ATRR that did the tracking. 
    The Northrop Grumman press release is here: . 
    It doesn't say which of the two satellites did the work.
    The STSS Demo pair has already demonstrated missile tracking at ranges 
    of several hundreds of kilometres under similar circumstances to the 
    reported tracking of the satellite: . I 
    guess the two events (missile and satellite) are similar in terms of the 
    'coldness' of the target.

     From the text I presume that STSS-ATRR did the obs on July 19.
    I have a hobbyists' elset for STSS-ATRR for August 13, and this
    one does show flybys within 100 km from NOAA-9 (15427) and
    NOAA-15 (25388). Did anybody do a more detailed analysis
    with an elset with a closer epoch?
