Belated report on the second batch of July 19-20 observations.

As first reported by Scott Tilley, MUOS 5 flash period has doubled, to 10 
minutes between successive brightness  peaks.

Approximate peak times (accurate to ~30 seconds) from my image series:

UT (Jul 19-20)

23:34:02
23:44:22  <-- no image taken at 23:44:02
[coverage gap]
00:14:02
00:23:52

The spacecraft is still basically in the same GTO orbit it has been in since at 
least July 3rd.

Updated orbit:

MUOS 5
