    Brad Young's observations,  made from Siding Spring with the object
at a distance of 27500 to 45500 km over 36 minutes,  give us a decent
orbit for this object :

    The residuals are quite high,  but that's to be expected with a
booster that's still venting.  The orbit matches that expected by
Jonathan McDowell reasonably well :

    Further data would,  of course,  be welcome.  As I write this (13
August 14:00 UTC),  the object is about twice as far away as the moon,
so I'm not getting my hopes up.  Unless somebody else imaged it and
hasn't posted astrometry yet.

    Thanks,  Brad!
