 Standard magnitudes for NOAA satellites
 ---------------------------------------

 From Russell's observations (1980 Jan 01 to 1995 Nov 30) I have derived
 standard magnitudes (1000 km, 90 deg) for NOAA satellites. There are
 323 observations by Russell, but only 58 are marked steady and in pairs
 (many flashing or with regular or irregular brightness variations).

 TIROS N         1978-096A     6   3.09 +/- 0.78  -0.0615 +/- 0.0230
 NOAA 06         1979-057A     4   5.95 +/- 1.31  -0.0046 +/- 0.0333
 NOAA B          1980-043A     5   5.46 +/- 1.01   0.0447 +/- 0.0330
 NOAA 07         1981-059A     8   5.37 +/- 0.24  -0.0304 +/- 0.0114
 NOAA 08         1983-022A     2   5.89            0.0705           
 NOAA 09         1984-123A    14   6.31 +/- 0.15   0.0050 +/- 0.0102
 NOAA 10         1986-073A    14   6.53 +/- 0.20   0.0101 +/- 0.0094
 NOAA 11         1988-089A     5   5.72 +/- 0.21   0.0011 +/- 0.0108
 NOAA 12         1991-032A     0                                    
 NOAA 13         1993-050A     0                                    
 NOAA 14         1994-089A     0

The RAE-Tables have for TIROS N and NOAA B to 12:
Shape and weight (kg): Cylinder+panel, 723 to 735 (in orbit)
Size (m)             : 3.71 long, 1.88 dia, (6.8 span NOAA 12)

World Wide Launches have for NOAA 13 & 14:
Shape and weight (kg): Cylinder+panel, 1013 & 1070 (in orbit)
Size (m)             : 4.18 long, 1.88 dia


 column 1 : name
 column 2 : international designation
 column 3 : number of observations
 column 4 : standard magnitude
 column 5 : phase coefficient


AMENDMENTS:

Ferret-D is the old (western) name of the Russian Sigints with orbits
of 635 x 665 km, 82.5 deg. The actual name is Tselina.
(Tselina-2 Sigints are at approx. 850 km, 71 deg)

Common names for 89-5A and 90-4A (low altitude comsats) are:
 COSMOS 1992     1989-005A     2   7.18            0.0333           
 COSMOS 2056     1990-004A     2   6.50            0.0105
