 Standard magnitudes for early Ferrets
 -------------------------------------

 From Russell's observations (1980 Jan 01 to 1995 Nov 30) I have derived
 standard magnitudes (1000 km, 90 deg) for 35 early Ferrets with initial
 orbits of approx. 620 x 646 km, 81.2 deg.

 Cosmos 476, 542, 604, 673, 744, 756, 808, 851, 895, 925, 1116 decayed.
