Tom Wagner Wrote At 21:53:11 I watched Envisat emerge from the earth's shadow. It came into view in Bootes. According to Heavens-Above it was a mag 3.7. Much to my delight, about 4 seconds after Envisat faded into view, another satellite,maybe two magnitudes fainter, faded into view, also in Bootes but a couple degrees higher (as I recall) than Envisat. The second satellite was traveling on a parallel course with Envisat but was moving more slowly. Can anybody determine what that second satellite might have been? Well I get the following in the area and moving at parallel tracks. OSCAR 19 (LUSAT) 1 20442U 90005G 02105.13337598 .00000610 00000-0 24516-3 0 7382 2 20442 98.3822 172.7211 0013027 45.9032 314.3214 14.31500835638367 CZ-4 DEB 1 26441U 99057KN 02105.13892161 .00010372 00000-0 31141-2 0 3995 2 26441 98.4212 172.6177 0103414 153.6946 207.1815 14.39803406103290 Here is some data from the oig IntID/Name CatNo Source period Incl Apogee Perigee RCS ------------ ----- ------ ------ ------ ------ ------- -------- 1990-005G 20442 ARGN 100.6 98.4 796 777 0.2579 OSCAR 19 (LUSAT) Launched (1990/01/22) 1999-057KN 26441 PRC 100.0 98.4 825 695 0.6601 CZ-4 DEB Launched (1999/10/14) Lusat or Oscar 19 is a amateur radio satellite. CZ-4 deb was part of the CZ-4 rocket used to lauch the CBERS 1 and SACI 1 satellites. When the rocket came apart in orbit, it put different parts in different orbits. Both objects were predicted to be slightly ahead of envisat at the time of his observation. CZ-4 deb was 4 seconds ahead or early compared to envisat using the above elements. Lusat was around 1 seconds early based on the elements above.
