The updated elements below are based on observations by Russell Eberst, Dave
Waterman and Leo Barhorst:


NOSS 3-8 (A)                                           1015 x 1197 km

NOSS 3-8 (B)                                           1014 x 1199 km
1 42065U 17011B   17080.10546761 0.00000000  00000-0  00000+0 0    05
2 42065  63.4517 101.4242 0123397 178.4731 181.6695 13.40829310    02

rms 0.03             From 7 observations March 19.85 - March 21.13 UT


At epoch time of the elsets above, the two objects were separated by 50.5 km.

The daily change in separation distance is now clearly flattening and it
actually looks like a separation of ~50.0 km is the aim, to be reached ~21 days
after launch (i.e. March 22-23).

"DaL" = Days after Launch:

DaL	sep(km)
----------------
1.387	42.7
5.417	171.4
6.457	190.4
7.277	202.0
8.623	172.3
9.592	148.9
11.382	120.2
14.440	77.8
18.095	53.7
19.362	50.5
---------------

The difference in orbital period of the two payloads is also decreasing.
