 Standard magnitudes for Ferret D satellites
 -------------------------------------------

 From Russell's observations (1980 Jan 01 to 1995 Nov 30) I have derived
 standard magnitudes (1000 km, 90 deg) for 36 Ferret D satellites
 (635 x 665 km, 82.5 deg).

 COSMOS 1025     1978-067A    32   5.25 +/- 0.21   0.0062 +/- 0.0055

 Cosmos 1025 has had an initial orbit of 640 x 668 km, incl. 82.5 deg.
 Possibly, this was a test flight for the Ferret D satellites.
