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
