Kevin Fetter's UNID of 2017 July 02 UTC correlates with USA 224 (11002A / 37348), which is the primary satellite in the KeyHole eastern plane. The following search TLEs span the known range of mean motion: USA 224 259 X 969 km 1 99991U 17183.19664847 .00016313 00000-0 15000-3 0 08 2 99991 97.9000 294.9222 0508000 171.7419 189.2574 14.84000000 00 USA 224 259 X 1000 km 1 99992U 17183.19662768 .00015949 00000-0 15000-3 0 03 2 99992 97.9000 294.9227 0529400 167.2780 194.2421 14.78999999 08 USA 224 259 X 1039 km 1 99993U 17183.19660555 .00015519 00000-0 15000-3 0 09 2 99993 97.9000 294.9237 0555000 162.6429 199.4630 14.72999999 07 I assumed that the perigee height had not changed since the summer of 2016, when the object was last observed. In each solution, I fixed inclination, eccentricity, mean motion and rate of decay, all of which are guesses. The solutions with lowest mean motion yielded the lowest residuals.
