    I decided to put to paper details of the recent "Unknowns"
    I have found as I am loosing track (no pun intended) of 
    what is what.
    
    
    Unknowns for 2006:
    ---------------------------
    
    #91054  - identified as 87051J - no longer "unknown"
    
    #91055  - identified as 04052A - no longer "unknown"
    
    #91056  - identified as 94086G - no longer "unknown"
    
    (The above three arose as a result of my stupidity - I used
     the wrong element database! )
    
    #91057  - medium earth orbit, inclination around 16 degrees-
              still unknown. Faint.
    
    #91058  - identified at #90046 so not an unknown
    
    #91059  - drifting geostationary - lost again as now out of
              my sky. Inclination ~ 2 degrees, n = 1.007,brightish.
              Not yet assigned a 900** number.
    
    #91060  - geostationary - now tracked as  #90053
    
    #91061  - recovery observation XSS 11 so no longer unknown.
    
    #91062  - identified by Mike McCants as 90-102G and confirmed,
              no longer unknown.
              
    #91063  - unknown - suspected it was a night flying bird -
              no longer unknown. Orbital period around 16 revs/day!
              
    #91064  - medium earth orbit (?) - large object - bright.
              may be a 64 degree inclination high eccentricty
              object - still unknown
              
    #91065  - geostationary - still to confirm with a second observation
    
    #91066  - recovery observation of #90006 - no longer unknown
    
    #91067  - originally reported as being possibly #90005 on 23rd May
              and found not to be the case, so now called #91067 06143GEO
              - inclination not well defined but less than 15 degrees ?
              Large object, steady, bright.
              
    #91068  - originally reported as being possibly #90027 on 28th May
              and found not to be the case, so now called #91068 06148MEO
              Large object ,inclination about 24 degrees, steady, bright.
    
    
    Summary:
    -----------
    
    Current unknowns are therefore :
    
     #91057, #91059, #91064, #91065, #91067 and #91068.
    
    
    Hope I have all this correct!
    
    My special thanks to Mike McCants, Ted Molczan and Scott Campbell
    for producing possible orbits to fit the limited arc observations.
    
    Cheers
    Greg
