    This object turns out to be the object Hj0110 first observed by 
    asteroid observer 678 soon after
    launch utilizing a 70mm lens f2.8 + CCD back in October 2005
    for observations see  bill Gray's Pseudo MPEC  at
    Some seesat-l members should be able to see it as its mostly brighter 
    than mag 13.
    One wonders why it took Spacetrack so long to catalog it
    AS a comment , from this objects orbit I am certain that the payload 
    utilized a super hohmann transfer
    rather than the usual GEO transfer orbit. That is at first apogee the 
    inclination was lowered and
    the perigee raised to near GEO height. Later a rocket firing at 
    perigee circularized the orbit.
