RE: Need TLE for Falcon R/B

Space-Track elements are now available for 65 objects from the SL1.17 launch (21-017). The four non-Starlinks are -BN, -BP, -BQ, -BR, -BS. The first four are marked as debris and have similar decay numbers so presumably are the launch clamp bars.  -BS (47786) is unidentified and matches observations of the Falcon 2nd stage to date, I think.

Regards

Richard

Hi Ted and Marco.
Thank you for helping.

Now let's try to observe Falcon in the sky.
