B.  Text of Launching Announcements.

1992-009A  USA-79 was launched on February 23, 1992 by the U.S.

1992-008A  COSMOS 2180 was launched on February 17, 1992 by the C.I.S. using
           the COSMOS launch vehicle to continue space research.  Initial
           orbital parameters: period 104.9 min, apogee 1028 km, perigee 980 km,
           inclination 82.9 deg.   

1992-007A  JERS-1 was launched on February 11, 1992 using the H-1 launch vehicle
           from Tanegashima Space Center, Japan.  Initial orbital parameters:
           period 96 min, apogee 579.9 km, perigee 558 km, inclination 97.7 deg.
           The national name of JERS-1 is FUYO-1 (meaning "rose mallow" in
           English).

1992-006A  USA-78 was launched on February 10, 1992 by the U.S.

1992-005A  COSMOS 2177, COSMOS 2178, and COSMOS 2179 were launched on January
 through   29, 1992 by the C.I.S. utilizing the PROTON launch vehicle to
1992-005C  continue space and navigational research.  The satellites have
           been put into a near-circular orbit with the following parameters:
           initial period 11 hr 16 min, distance from the Earth's surface 19,150
           km, inclination 64.5 deg.


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.  ("NNSS" denotes U.S. Navy Navigational Satellite System;
* indicates updated information since the last issue.  SPACEWARN would
