Russell observed the NROL-79 payloads last night. Object A was ~3.9 seconds
early and object B ~3.7 seconds early relative to my previous 4-day old elsets here:

The following updated orbits are based on observations by Russell Eberst, Leo
Barhorst and Marco Langbroek, March 3 - March 7.


NOSS 3-8 (A)                                           1010 x 1204 km

2 42058  63.4493 137.0271 0129796 178.3830 181.7640 13.40590579    05

rms 0.02                 from 16 observations March 3.07 - March 7.18


NOSS 3-8 (B)                                           1010 x 1204 km
1 72059U 17011B   17066.15821451 0.00000000  00000-0  00000+0 0    02
2 72059  63.4507 137.0357 0129795 178.5024 181.6417 13.40659022    06

rms 0.02                 from 12 observations March 3.07 - March 7.18


The (A) object has been catalogued as #42058 by JSpOC, the (B) object not yet.
Note that JSpOC has now assigned the NORAD number we initially used for the (B)
component, #452059, to "Object KH" released by the ISS. I therefore used a 70000
number for NOSS 3-8 (B).

At March 7 the two objects were further apart than on March 3: about 170 km
separated. This is more than for the operational NOSS so at one point, they will
come closer again I guess.
