    Thank you for your observation. Here it is after reduction, and in IOD format:
    
    29651 06 057A   9999 G 20080218232156000 28 25 0533409-003600 48 S
    
    Object was 7 s late, and 0.31 deg above the track predicted by the elements I
    posted earlier. (Heavens-Above has the same set.)
