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
