This unknown is not NOSS 6 (A) [14690/84012A]. This is what satfit reported: 14690 0.689 126.640 0.138 19736A 116.964 Here, the 2nd column is the difference in mean anomaly, and the 3rd column the difference in RA of the ascending node. This is for the case of using the last TLE, but allowing for changes in mean anomaly and RA of the ascending node. For a lost satellite to be a match to the unknown, the difference in RA of the ascending node, can not be large (a few degrees at max). In this case, the 126.6 degree offset in RA of the ascending node means that your unknown can not be NOSS 6(A).
