Notes:
------
(1) Unknown #91043 ( also briefly known as #91046) is now in the
CLASSFD.TLE file as #90042.
(2) Looks like #91047 and #91048 are real "unknowns". Since the periods
are not accurately known and they are in very elliptical orbits it
is going to be virtually impossible to get accurate orbits unless
seen again by sheer chance. Anybody got ideas on how this kind of
problem can be solved ? Geostationaries are easy - look at the same
place the next night at about the same time and most times the
satellite will be in the field of view.
(3) Although my observations are reported to arc seconds the observations
are nowhere near that accurate. I use "quick and dirty" methods to get
my positions as rapidly as possible so none of the measurements are
of astrometric quality. A very rough calcualtion shows that 1 pixel
has a size of around 20 arc seconds, so at best any position is plus/
minus 20 arc sec. ( I know I should not do such calculations- bound to
have done something wrong!!)
(4) I think that concludes 01 Dec 2005.
Cheers
Greg
