To the observers


Here are some new images of the STrZ-spot from last night,taken in unsteady air with constant clouds and wind
but fair seeing though.
According to the images,the spot has decreased in brightness/contrast again,but images in better seeing are
required to confirm that.
The large spot seems to have the shape of an eye now,with possibly a darker center.

Added is also an overview-image to show the outer moons.The animation show the rotation of the spot together with Tethys.






The animation shows the storm in the STrZ of Saturn on Febr 26, March 15 and
April 01. We see differences as
the size(especially between Febr 26 and the later images),and shape,but
particularly interesting is a difference in
altitude which is noticable between the March 15 and April 01 image.

On this last image,it seems the SEB has more influence on the spot.In the
March 15 image,we see that the situation is rather reversed,
and the spot itself seems to have more influence on the STB.Rather I would
say,it disturbs slightly the nothern edge of the STB.

As last, an important difference between the March 15 and April 01 image, is
that the latest shows a clearly
perceptible dark center,while the appearance of the spot is darker.
