 Standard magnitudes for KH-11 Satellites
 ----------------------------------------

 From Russell's observations (1989 Aug 27 to 1995 Nov 30) I have derived
 standard magnitudes (1000 km, 90 deg).

 KH 11-6         1984-122A   282   4.09 +/- 0.06   0.0283 +/- 0.0021
 KH 11-7         1987-090A    59   4.20 +/- 0.16   0.0314 +/- 0.0051
 KH 11-8         1988-099A   351   3.98 +/- 0.07   0.0273 +/- 0.0022
 --------------------------------------------------------------------
   ALL                       692   4.05 +/- 0.05   0.0283 +/- 0.0015

 92-83A doesn't look like a KH-11 satellite:

 USA 86 (KH-12?) 1992-083A    89   5.05 +/- 0.10   0.0205 +/- 0.0030
