IGS-1 H2A Image 2009/01/28(UT)

I captured a good pass of a low orbit Japanese H2A rocket,my 3th(successful)session
of this object.The rocket with dimensions of 13.5x2.5 meters is a second stage and moves in an orbit of 425.9 x 482.9 km
with an inclination of 97.0 degrees.the pass was a favourable one from SSE-NNW and 82° elevation(ENE).
As this object is in the same orbit-class as the ISS(although it a good 100km higher)the size of this body
on the ccd appears comparable with that of some single modules of the ISS.It is still a very difficult object
A stack of the best frames and best possible image processing reveals something interesting,
but something I already suspected;the first image shows only a bright lighted side(the brightest side lighted by sun).
The better processing shows a totally different view of the object.Its more width,and it seems we see it from an
angle We see not the full lenght!
