The surface features
On the NASA-picture the most important features of the Jupiter-surface are named. Zones and bands are dynamic formations. So they can change their appearance.

The Great Red Spot (GRS / in German: GRF)
The Great Red Spot is a giant storm region, located in the SEB. It is much biger than the earth. It is a very long living formation,
and was first observed in the 18th century. At time of discovery the color was insensiv red, but color changes in long-term.
At the moment the GRS has a yellowish color.

The planet came onle 23° above the horizon, and was just above the roof of the neighbour-house, when this picture was taken.So the seeing was bad.

The right image was taken through an methan-band filter. This darkens the planet, but the mons in front of the planet where clearly visible.

Becourse of the 50nm - Bandwidth of the filter there can also be seen a infrared-image of the clouds of jupiter.

Near the left edge of the planet the GRS is visible.




5.8.2007

In 2007 the conditions to observe Jupiter are not good. The planet came only 19° above the horizon, when this picture was taken.

This photo is a composit of 2 videos. The first one showed only jupiter, for the second one the scope was shifted a little to right, so the mons could be pictured.

Top:
The white spot at the right limb is moon Europa.
The dark spot left is its shadow.
The Great Red Spot comes just around the left limb.


Middle:
This picture is taken only 11 minutes later than the above one.
Europa is just beside the planet.

Bottom:
Europa and its shadow has moved.
On Jupiter's left side is the moon Io.

The Great Red Spot has moved near to the central meridian.
A little bit left under the GRS there is the very new "Red Spot Junior " (arrow). Early in 2006 a big "white oval", located in the STB, darkened to nearly match the GRS itself. As of April, "Red Spot Junior" was following behind the GRS by about 1 hour of Jupiters rotation.
