2009/04/29_ISS with Progress 32 observation
Yesterday,on May 6, the Progress 32 undocked from the ISS. Here is an image from
April 29 during a favourable pass,showing the docked Progress 32 at the Pirs docking
compartment and seen from a particular angle.The station was in approach and this
causes the effect that the 7 metres long Progress seems to stick out more to the aft
end and appears to be located behind the Svezda solar panels.The solar panels
of the Progress are also visible very well.
Note also,visible thanks to the particular angle,the Experiment Logistics Module-Pressurized
Section(ELM-PS) on top of the JEM(Kibo),normally not always easy visible because it is
located on the zenith side.

This pre- STS-127 image is my last image showing the Japanese Experiment Module (JEM)
in its configuration before the addition of the Japanese Exposed Facility (JEF), in the period
from the moment when it was latched in place on the Harmony Node on June 3, 2008.
Some nice detail can be seen along the backbone (trusses) as well.

One of the thing which were most obvious when I first saw this image
was the impression of absence of the Columbus module (right side image),
but this effect is caused due to the Canadarm 2 which was at that time positioned
at the starboard side of the Harmony Node!
Another obvious thing is the seemingly absence of the last added Starboard 6 solar panel,
caused by the almost edge-on position of the panel, probably for test intentions.

ISS April/May lighting angle story
I have captured many passes of the International Soace Station, and almost
every pass, I see a different observing- and lighting angle of the station.
Many passes are not very favourable, even during higher passes, due to
a less favourable viewing or lighting angle. What I noted the last years,
is the almost optimal lighting angle for the backbone structure of trusses
during the months late April / May. This was for either my 2008 May sessions,
and April/May 2009 sessions obviously the case.
The image shown here, is one of them. Taken April 29, 2009. It seems the case
that with an optimal lighting angle for the trusses, the lighting angle for the
laboratories, especially the Russian ones is the reversed. Also note that the
stations main radiators are almost fully hidden behing shade. While during
most of the general passes, these are one of the most obvious elements visible
in an image. In this case just a little piece of the Port side mid-radiators is visible,
seen as the bright spot seemingly flying off the station.
Imagery: 10inch Newtonian, manually tracked using a 6x tracking scope.
