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.
