B.  Text of Launching Announcements.

1991-080A  STS-44, the space shuttle Atlantis, was launched on November 24, 1991
           by the U.S.  Its mid-deck payload consists of a Department of Defense
           satellite.

1991-079A  COSMOS 2172, a communications satellite, was launched on November 22,
           1991 by the U.S.S.R. using the PROTON carrier rocket.

1991-078A  COSMOS 2171 was launched on November 20, 1991 by the U.S.S.R. to 
           continue space research using the SOYUZ carrier rocket. 

1991-077F  COSMOS 2170 was launched on November 12, 1991 by the U.S.S.R. to
           continue space research utilizing the same booster rocket that 
           launched COSMOS 2165.  Initial orbital parameters: period 113.8 min,
           apogee 1432 km, perigee 1385 km, inclination 82.6 deg.

1991-077E  COSMOS 2169 was launched on November 12, 1991 by the U.S.S.R. to
           continue space research utilizing the same booster rocket that 
           launched COSMOS 2165.  Initial orbital parameters: period 113.8 min,
           apogee 1432 km, perigee 1385 km, inclination 82.6 deg.

1991-077D  COSMOS 2168 was launched on November 12, 1991 by the U.S.S.R. to
           continue space research utilizing the same booster rocket that 
           launched COSMOS 2165.  Initial orbital parameters: period 113.8 min,
           apogee 1434 km, perigee 1392 km, inclination 82.6 deg.

1991-077C  COSMOS 2167 was launched on November 12, 1991 by the U.S.S.R. to
           continue space research utilizing the same booster rocket that 
           launched COSMOS 2165.  Initial orbital parameters: period 113.9 min,
           apogee 1437 km, perigee 1402 km, inclination 82.6 deg.

1991-077B  COSMOS 2166 was launched on November 12, 1991 by the U.S.S.R. to
           continue space research utilizing the same booster rocket that 
           launched COSMOS 2165.  Initial orbital parameters: period 114.0 min,
           apogee 1440 km, perigee 1408 km, inclination 82.6 deg.

1991-077A  COSMOS 2165 was launched on November 12, 1991 by the U.S.S.R. to
           continue space research.  Initial orbital parameters: period
           113.9 min, apogee 1436 km, perigee 1396 km, inclination 82.6 deg.

1991-076A  USA-72 was launched on November 8, 1991 by the U.S.

1991-075A  INTELSAT VI F-1, a telecommunications satellite, was launched on
           October 29, 1991 from the Kourou Space Center using the ARIANE
           booster rocket.  Initial orbital parameters: period 716.1 min,
           apogee 35,738 km, perigee 4533 km, inclination 4.4 deg.  The
           spacecraft is capable of handling 120,000 telephone, television
           broadcast, and other services simultaneously; its system of
           directional antennas allow the satellite to cover the entire
           American, European, and African continents by means of a
           reconfiguration.


C.  Spacecraft Particularly Suited for International Participation (Category I).

    1. Spacecraft with essentially continuous radio beacons on frequencies less
than 150 MHz, or higher frequencies if especially suited for ionospheric or
geodetic studies.  (Square bracketed indicate updated information since the last
issue. SPACEWARN would appreciate suggestions to update this list.)

atmospheric studies.  Note: For maneuverable spacecraft the prediction may be
invalid.)
