WGS 8: Spiraling Towards Geostationary Orbit...

Hi All

Last night I also set upon WGS 8 with the interest of updating its orbit 
as the eccentricity of the orbit has been noted to be decreasing at a 
slow but steady rate with other parameters remaining largely fixed...

Visual observation haveconfirmed this. WGS 8 appears to be taking a long 
time going round and round and slowly spirally into geostationary orbit. 
It appears they first focused on approaching a synchronous mean motion 
and then slowly nudge towards a geostationary orbit using the Ion drive 
presumably as no significant impulse change in orbital observations have 
been noted by visual or other means in a very long time...
