Thanks Patrick for the identification of the object I observed on June 4
2017.
There was some confusion with the Falcon objects but time and angular
velocity didn't correspond with my observation.

The CZ3 third stage 31116/07011B) is very spectacular, bright and very
fast.  Calsky predict it to decay around July 31 2017 but with an accuracy
of about 11 days...

I observed it near perigee with a range of only 157km.(and comming from an
apogee of 9368km.)

If you got a chance to observe it, I would certainly do it.  It is also a
tumbling object(near perigee) with very bright maxima(at least mag 0) and a
period of maybe 3s.

BTW, the first element sets issued by Spacetrack of the Falcon objects were
mixed up with each other...(cannot publish them here due to policy)

"At 21:19 another fast moving object
from W->E and flashing from mag 0
to inv with about 3s was passing by
through UMa.
I believe this was the Falcon rocket from
the recently launched Dragon capsule."

Could this object have been 2007-011B
(a Changzheng-3A upper stage)?
