(Note that the negative residual implies that it was running this much early with respect to my prediction.) My latest SatEvo analysis fits the five elsets since 97075.38 with a mean residual of 3.6s and a maximum residual of 9.4s. It suggests that decay should occur at March 16.950 (22.48 UT) with the object in daylight 5,000 km S of Hawaii over S Polynesia. The evolution runs...
