I was curious about the object that Cees observed on Jun 3 and 4 UTC, that he suspected was NOSS debris. Below are my
observations:

99448 15 654A   2701 G 20150606054315880 17 25 1129078+392136 66 S
99448 15 654A   2701 G 20150606054322250 17 25 1138799+390738 28 S

IOD format: http://www.satobs.org/position/IODformat.html

Site 2701: 43.68764 N, 79.39243 W, 230 m

Instrument: 25 X 100 binoculars

Its standard visual magnitude appears to be about 5.5 (1000 km, 90 deg phase angle).

The following TLE is based on the complete set of observations:

15654A                                                  459 X 1257 km
1 99448U 15654A   15157.21577995  .00040840  00000-0  52880-2 0    03
2 99448  63.2750 103.4606 0551462  85.7000 280.6841 14.10126829    05
Arc 20150603.97-0606.24 WRMS resid 0.012 totl 0.010 xtrk

The arc is fairly short, so the decay term is somewhat in doubt, but it tends to confirm that this almost certainly is
debris.

I suspect that SRP (solar radiation pressure) may be a significant component of the decay term. This could be an
interesting object to attempt to track long-term.
