Hi there,

I took the object "1258" of my video[0] and got this TLE:

1 00000U OrbDet   21182.06166389  .00000000  00000-0  00000+0 0    05
2 00000  97.5008 310.8209 0078575  96.1633 313.6689 14.97334383    05

Can anybody point me to an early tle of the transporter 2 mission or one of
its satellites or maybe you have some cospar IDs then I will try to look
I would like to compare it.

For Transporter1 and its satellites I remember early TLEs but for
Transporter2 I don't. If there was also such a set and someone of you have
it, it would be great to get them. :)

Or what CosparID would you take that is in open TLE archives that could be
closest? Like the Falcon9 upper stage or one of the bigger satellites out
of the released 88 satellites.


Best regards,
