Scott, your UNID is among the objects tracked by ISON. Your observations were about 55 s late and within a few
hundredths of a degree cross-track relative the following TLE derived by Cees Bassa from ISON's 2016 July 25 data:

SO  42000                       3.1                 252km  x  22561km
1 81018U 12752A   16211.52953704  .00000000  00000-0  14678-2 0    02
2 81018  26.0304 348.8237 6272103 178.7642 129.5988  3.66050504    41
# 1008 positions, 4.7 km rms

Adding your latest MUOS 5 observations to your earlier ones, and those of Peter Wakelin and Brad Young yields the
following elements:

MUOS 5                                               15776 X 35699 km
