B.  Text of Launch Announcements.

1993-060A COSMOS 2264, a C.I.S. military spacecraft, was launched by a Cyclone-M
          rocket from Baykonur cosmodrome at 00:43 UT. Initial orbital     
          parameters are period 92.9 min, apogee 437 km, perigee 429 km, and  	
          inclination 65 deg.

1993-059A COSMOS 2263, a C.I.S. spacecraft, was launched by a Zenit rocket     
          from Baykonur cosmodrome at 07:36 UT. Initial orbital parameters
          are period 102 min, apogee 880 km, perigee 852 km, and inclination
          70.6 deg.

1993-058C ORFEUS-SPAS, a U.S.A. spacecraft, was released from STS 51. Initial 
          orbital parameters are period 90.1 min, apogee 304 km, perigee 270
          km, and inclination 28.4 deg. It was later retrieved by STS 51. 

1993-058B ACTS, a U.S.A. geostationary communications spacecraft, was launched 
          from STS 51. Initial orbital parameters are period 719 min, apogee  	
          39,957 km, perigee 323 km, and inclination 15.3 deg.

          UT. It carried experimental resources for studying the effect of
          atomic oxygen bombardment on structural materials, for protein crystal
          growth, and for polymer membrane processing. It launched ACTS
          spacecraft and released and recaptured ORFEUS-SPAS.

          station. It replaces a Navy UHF satellite that was launched into a
          useless orbit. USA 95 is the second of a constellation of ten planned
          Navy communications spacecraft. Initial orbital parameters are period
          485 min, apogee 26,970 km, perigee 285 km, and inclination 27.1 deg.

          at 16:22 UT. It carried relaying instruments to uplink and downlink
          weather data from the Mediterranean and adjacent areas obtained by
          about 50 ground stations. Initial orbital parameters are period 104.1
          min, apogee 980 km, perigee 945 km, and inclination 82.5 deg.

1993-055A METEOR 2-21, a C.I.S. meteorological spacecraft, was launched by a
          Cyclone rocket from Plesetsk cosmodrome at 05:40 UT. Initial orbital
          parameters are period 104 min, apogee 980 km, perigee 945 km, and
          inclination 82.5 deg.

1993-054A USA 94, a U.S.A. spacecraft in the GPS series, was launched by a
          Delta-2 rocket from Cape Canaveral Air Force station at 12:38 UT. It
          joins 21 others in the constellation. Initial orbital parameters are
          period 11 hr, 56 min; apogee 20,221 km; perigee 20,074 km; and
          inclination 54.9 deg.

1993-053A RESURS F-19, a C.I.S. natural resources spacecraft, was launched by a
          Soyuz rocket from Plesetsk cosmodrome. Initial orbital parameters are
          period 88.7 min, apogee 267 km, perigee 188 km, and inclination 82.6
          deg.

    1. Spacecraft with essentially continuous radio beacons on frequencies less
than 150 MHz, or higher frequencies if especially suited for ionospheric or

    4. Miscellaneous Items. (This section contains information/data that are 
entered on occasion and may not be repeated in each issue of the SPACEWARN 
Bulletin.)

RADCAL (1993-041A/22698), reported in SPX-477, is now identified as a U.S.A.
spacecraft launched from Vandenberg Air Force Base. It is intended to help 
calibrate radar target cross section data.

There has been much confusion in the names and IDs of three U.S.A. spacecraft.
Through a call to USSPACECOM on 28 September, SPACEWARN has now identified the 
finally corrected version as follows:
