Is it possible that the large ndot/2 is due to
uncertainty in the mean motion. Yesterday's
value of 13.4021 was a little less than I
expected, assuming that it would match those
of NOSS 2-1 and 2-2. Today's value is a little
higher than I expected. Of course there is also
the possibility that some manouevring has 
occurred, perhaps related to the deployment, which 
may or may not have taken place yet.

There was one observed piece from the 2-2 launch
that had an ndot/2 of .00007, that I suspected
was due to SRP.

I suspect that after a few days obs, the mean motion 
will settle down around 13.4026, and the ndot/2 
will return to a low value.

bye for now
