#MUOS1 is on the move as noted by @astrobrock. I aimed the S-band dish low to my western horizon and noted her in 'storage mode' as can be seen by the 600 second period of its carrier. During MUOS5's trip to GEO we correlated this to optical characteristics of s/c rotation rate. 
#MUOS are based on the Boeing A2100 satellite bus. We have seen others of this type perform similarly. SDS-3, GOES etc. We first got a good look during the near miss with #MUOS5. MUOS5 is effectively stranded at ~106W. spaceflight101.com/spacecraft/muo…
