David Brierley and Russell Eberst have reported observations made on 2007 Apr 04/05 UTC, of objects in the eastern IGS plane, which is where the 06037A and 07005A launches were targeted. Russell's four 07005B points (2 each on consecutive passes) yield the following estimated elements: IGS-R2 0.0 0.0 0.0 3.3 v 1 30587U 07005B 07095.01809396 .00000000 00000-0 00000-0 0 05 2 30587 97.3000 215.9109 0002000 274.0995 86.0015 15.26044265 04 Based on its brightness, I am confident that it was the radar payload. David's single point reported as 07005A, may be 06037A, the primary optical payload in the plane. If the 03009A/B pair are a reliable guide, then the object David observed trailed 07005B within several minutes of the expected time interval. Here are approximate elements: IGS-O2 0.0 0.0 0.0 5.7 v 1 70000U 07095.04155223 .00000000 00000-0 00000-0 0 03 2 70000 97.3000 215.9235 0002000 274.1091 85.9919 15.26044265 07 Russell's 0700500 preceded 07005B by 2.5 minutes, and appears to be coplanar with it; therefore, I suspect it is 07005A, the experimental optical payload of the 07005 launch, which I call IGS-Oexp. Russell obtained two points (one each on consecutive passes) of an object, which he called 07005C, but which I suspect may be 06037E. Here are approximate elements: 1 70001U 07095.02140296 .00058835 00000-0 10000-2 0 08 2 70001 97.2400 215.1840 0020004 350.0347 10.0506 15.51213549 09 Ted Molczan ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
