I'll take part of the blame or credit ;)    I think I'm the one who initially asked Joe to add 47438 as UVSQSAT, which has subsequently been appropriately changed to UVSQ-SAT for the name.    Object 47438 matched so very well, for so very long, that it seemed reasonable to help users by including it, even if it had to be changed later...the idea being, hopefully more people would track it!  I haven't tracked it myself for a week or so, too many other matters at hand.  But it's fun to copy it at 9600 bpsk!  A different "sound" that we are used to hearing!

Your expertise in identification, Nico, is always appreciated.    If it's not 47438, I trust you'll let us know ;)

Thank you Joe,

Of course it is a good idea to offer a preliminary solution by
suggesting to use object 47438 for UVSQ-Sat for the time being.
It's just that Ray's post seemed to suggest that a positive
identification had been made, that provoked my reaction.

No problem, we'll just have to wait a while before we can
identify this satellite. And I would not be surprised if it will
appear to be object 47438 anyway.
