Text of Launch Announcements. 1996-041A USA 126 is the latest member of the American constellation of GPS spacecraft and was launched from Cape Canaveral by a Delta-2 rocket. It will replace an aging member of the constellation. Initial orbital parameters were period 723.6 min, apogee 20,365 km, perigee 20,272 km, and inclination 55.03 deg. The constellation is detailed in section C-2 below. 1996-040B TURKSAT 1C is a Turkish geosynchronous communications spacecraft that was launched by an Ariane 44L rocket from Kourou in French Guiana at 22:30 UT. After parking at 42 deg E, the 2,100 kg spacecraft will provide radio and TV communications to Turkey and neighboring countries. 1996-040A ARABSAT 2A is a geosynchronous communications spacecraft of the 21-nation consortium and was launched by an Ariane 44L rocket from Kourou in French Guiana at 22:30 UT. The 2,100 kg spacecraft will provide radio and TV communications to the Middle East and neighboring countries. 1996-039A APSTAR 1A is a geosynchronous communications spacecraft that was launched by a Long March 3 rocket from Xichang center in south- eastern China. After parking at 134 deg E, the 2,800 kg spacecraft will provide TV coverage to the Asian-Pacific countries through its 24 C-band transponders. 1996-038A USA 125 is an American military surveillance spacecraft that was launched by a Titan 4 rocket from Cape Canaveral Air Station at 00:30 UT. 1996-037A TOMS-EP (Total Ozone Mapping Spectrometer-Earth Probe; also known as TOMS-EP96) is an American Earth science spacecraft that was launched by a Pegasus XL rocket from an L-1011 airplane over southern California at 00:48 UT. The 248 kg (fuel-free) and 103 W spacecraft carries a single instrument: a modified Ebert-Fastie polychromator with fixed exit slits at six near-UV wavelengths, which will monitor and store full-orbit data and downlink them over one or two ground stations. It is reported to be experiencing attitude control problems. The initial parameters of the circular, Sun-synchronous orbit were period 97.6 min, altitude 500 km, and inclination 97.4 deg. 1996-029F, USA 124 and USA 123 are American military spacecraft. -029E The others by the same launcher, 1996-029A, B, C, and D were reported in SPX-511 and SPX-512. C. Spacecraft Particularly Suited for International Participation. 1. Spacecraft with essentially continuous radio beacons on frequencies less than 150 MHz, or higher frequencies if especially suited for ionospheric or geodetic studies.

Entries marked "*" are updates or additions to the list.) All GLONASS spacecraft are in the general COSMOS series. The COSMOS numbers (nnnn) invoked by USSPACECOM have often differed from the numbers (NNNN) associated in Russia; when different, the USSPACECOM COSMOS numbers are shown in parentheses. The corresponding GLONASS numbers are Russian numbers, followed by the numbers in parentheses that are sometimes attributed to them outside Russia. The operating frequencies in MHz are computed from the channel number K. Frequencies (MHz) are L1 = 1602.0 + 0.5625K and L2 = 1246.0 + 0.4375K.

(This section contains information/data that are entered on occasion and may not be repeated in each issue of the SPACEWARN Bulletin.) NSSDC/WDC-A-R&S is an archival center for science data from many spacecraft. Some data are on line for electronic access. Please contact the Request Office, NSSDC, Code 633, NASA/GSFC, Greenbelt, Maryland 20771, U.S.A., for specific information (REQUEST@NSSDCA.GSFC.NASA.GOV). Information on the current status of the instruments on board from the investigators will be most welcomed. Precomputed trajectory files and orbital parameters of many magnetospheric and heliospheric science-payload spacecraft may be FTP'ed from NSSDC's ANON_DIR:[000000.ACTIVE] and its several subdirectories. (See the last page of the bulletin for the access method; a file in the ACTIVE directory named AAREADME.DOC outlines the contents.) It can also be accessed through the WWW URL http://sscop1.gsfc.nasa.gov/ssc.html This HTML also enables executing several codes related to the orbits of many geocentric science payload spacecraft. The codes related to the heliospheric spacecraft trajectories can be executed through URL http://nssdc/space/helios/heli.html Magnetospheric, Planetary, and Astronomical science data from many spacecraft may be accessed through links from the URL http://nssdc.gsfc.nasa.gov/ A LIST OF VISUALLY BRIGHT OBJECTS --------------------------------- Spacewarn Bulletin thanks Mr. Walter I. Nissen of the National Capital Astronomers for the following list compiled by him on 14 July 1996. Objects were observed during 1994-1996 by Walter I. Nissen, Jr., CDP, at latitude 41 N. Mr. Nissen is grateful for assistance from Goddard Space Flight Center, Smithsonian Institution and National Capital Astronomers. This list does not possess the universality of Mike McCants's catalog, but it does serve as a record of what can be seen under favorable conditions of illumination and reflection. This list supplements the similar list compiled on 7 July 1994, by Mr. Nissen and reported in Spacewarn Bulletin SPX-490. This list is complete for objects in orbit as of this date (14 July 1996) that were recorded at magnitude 4 or brighter. The magnitude shown is the brightest observed magnitude. When it was clear that a glint was being observed, the brightest observed glint is recorded after the asterisk. When both are provided, they may represent different passes. When the name is a simple number, the object is from the Cosmos series; "r" denotes rocket body.

The material it contains is based on guidelines in the COSPAR Guide to Rocket and Satellite Information and Data Exchange, COSPAR Transactions #8, December 1972, and various Committee on Space Research (COSPAR) resolutions. Hard copy recipients and electronic accessers are encouraged to disseminate the bulletin to interested individuals and institutions in their regions or countries. All bulletins beginning with January 1991 (SPX-447) are now available on line; the SPX number increases by one for each succeeding month (for example, the January 1993 bulletin is SPX-471).

The bulletin may also be accessed through the World Wide Web (WWW). The URL is http://nssdc.gsfc.nasa.gov/spacewarn/spacewarn.html. Users are urged to submit their comments and suggestions for the improvement of this bulletin to SPACEWARN Bulletin, World Data Center-A for Rockets and Satellites, Code 633, Goddard Space Flight Center, Greenbelt, Maryland 20771 U.S.A. Categories of Spacecraft To improve the effectiveness of international distribution of satellite and space probe information via the SPACEWARN system, spacecraft are identified in categories according to the urgency and detail of information needed by the scientific community as follows: CATEGORY 1: Spacecraft that carry essentially continuous telemetry or radio beacons, usually on frequencies less than 150 MHz. CATEGORY 2: GPS constellation of positioning/navigational spacecraft. CATEGORY 3: GLONASS constellation of positioning/navigational spacecraft. CATEGORY 4: Occassionally, a list of bright, orbiting objects of visual magnitude 4 or brighter. The bulletin also carries launch dates, international ID's and USSPACECOM catalog numbers, followed by a brief outline of the payload and orbital parameters, re-entry of major objects, and miscellaneous sections. These data are based on launch announcements or on information received from individuals, launching authorities, FBIS and USSPACECOM telexes, and news magazines.
