April 27; 20:54-21:03 UT (CM3=158-163)&
20:54-21:17 UT (CM3=158-171)for file SAT_20070427_2054-2117UT.gif

At least 2 dark spots as disturbances of the SEB,located in the
region of mid to south SEB.They tend to give the SEB-s a structured
appearance.Especially the gif SAT_20070427_2054-2117UT which shows
north up gives a remarkable view.

This type of spots seems first observed since early apparition
(Nov 7,2006 and some smaller SEBs spots until in December)with
approximately similar type disturbances,also with one bigger spot as
part of a group see;

Obvious is that they are observed very early and late in apparition only,
with a relative steady and quiet SEB in mid-appariton and during opposition
(aside the mid-SEB white spots).

This is an update of the observations done on April 27 in the
red light,showing moderate dark spots along the southern part
of the SEB(SEBs)in the earlier images.

The attached versions are more saturated in contrast revealing the more
cloudy character in the concerning region.

Very interesting is the comparison of the north with the south side
(south is up)in which the SEBn looks clearly more flat,against
a'cloudy'SEBs.
