| Ganymede begins its transit on Jupiter surface; in the right shot a comparison between the CCD image captured bt SCT 8" and the NASA simulator picture. The black spot on the biggest Jupiter satellite could be the Galileo Regio impact basin. | |||||||||||||||

 The
Giant near the Opposition, in this image (poor seeing), Ganymede ends its
transit while its shadows is projected on the Jupiter atmosphere; look at
the Dark Spot moving trough the STB. See the DRAFT
from G. Adamoli (UAI Hi-Res).

Venus near the maximum elongation. Three months before the transit on the
Sun.
|
Saturn: two months after the Opposition look at the Planet shadow over
the rings; compare this image with the "December" image shown
below.

Jupiter: Img (1).......The Europa satellite ends the occultation, an
excellent seeing permits to reach more and more details on the Giant's
atmosphere. Look at the blue festons on the equatorial belt. (2).......A
dark spot is moving through the Planet atmosphere toward GRS. (3)........A
comparison between two images at a distance of 9 months shows differences
in the area surrounding GRS. Only a dark spot appears actually in that
area vs. a dark matter stream in March now disappeared.

 Saturn: Saturn is now a few weeks before opposition and the globe's shadow on the rings cannot be seen. features are visible in this image on SEBs and a small storm is visible in other
images. The Encke division appears in this image. This feature is very
difficult to show considering the diameter of the used instument
(8-inches).

and 
The Lord of the rings and the Giant Jupiter. These planets are near the
opposition. Their diameter is quite larger than in september.

 Mars:
12.1 arc sec; The south polar cap is now very shrinked. See the difference
with the previous image.
|
|||||||||||||||
Vs. 
Mars: 13 arc sec; The southern hemisphere is still tilted toward us,
and has just passed the summer solstice. Last month we saw rapid shrinkage
of the polar cap, with some observers noting short-lived periods of
separation between adjacent areas of ice. The pole is very small now, and
southern regions such as Hellas which are sometimes bright with clouds or
frost are now dim and can be a challenge to make out, and can show some
interesting detail that you won't normally see during other seasons. It
seems to me that some of the dark areas also look a little different -
does Syrtis Major seem smaller to you than it does in winter? The
constantly changing, poorly mapped, and poorly explained shapes of Mars'
albedo features are always an interesting mystery, and fun to watch.

It is difficult to shoot a good quality image when the planet is near
the horizon. And in Oct 2003 Saturn is day by day rising earlier and
earlier. So I woke up at 4:30... Results are here!

Year 2003. The Mars Summer. The Great Opposition. The period is between
August and September.
