Here is the same elset, in standard NORAD SGP4 2-line format. The
B* term is an accurate estimate from the ndot/2 term. Of course,
the decay in this elset is low enough to ignore for the present

I believe that the difficulty we have had in converging on a stable
set of elements is due to manouevring by the object. I strongly believe
that the triad members will match mean motions with those of the
NOSS 2-1 and 2-2 members, estimated to be currently about 13.4026 rev/d.
NOSS 2-2 matched NOSS 2-1 when it was deployed, so it is reasonable to
expect the same of this launch. Also, the apparent manouevring from
a slightly lower orbit to the intended orbit makes sense. Presumably
each triad member will make the final manouevres to establish it self
in the planned orbit.

The lack of flashing on the pass Pierre observed may indicate that the =
deployment had begun, or was about to begin. Of course it could also =
been a result of the object's orientation with respect to the observer
and the sun. After the deployment, it will be interesting to see=20
if a discernible object remains. Perhaps that would offer a clue=20
helpful in finding its counterparts for NOSS 2-1 and 2-2.

bye for now
