    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
