Brad Young's observations on 2016 Oct 23 and Oct 26 UTC are sufficient to confirm that MUOS 5 has reached synchronous
orbit. The following are its approximate elements:

MUOS 5                                               34902 X 36672 km
1 41622U 16041A   16300.22418981  .00000000  00000-0  00000-0 0    05
2 41622   9.6752 320.6485 0210000 185.6936 224.2450  1.00274000    08
Arc 20161023.35-1026.22 WRMS resid 0.024 totl 0.000 xtrk

It is located at 105 W, which is the Western libration stable point, where synchronous spacecraft experience little or
no longitudinal drift. I discussed the significance of this in my recent post on estimates of MUOS 5's remaining fuel:
