Mists spread in the southern cap and also on the western edge

Here is a mars report performed last 06th march. with the 102mm refractor.
Caps well bright and withish,hood on the north,withish at the south. Hellas bassin〓edge〓bright.
Volcanoes for some covered it seems〓by〓white haze.
Strange clear equator zone merging and spreading from the limb: atmosph〓ric or albedo ground properties?
Atmosph〓ric〓at〓the limb obviously nevertheless.

Mars from last night: the sky cleared just after sunset,however clouds increased in thickness over the next 20 minutes as I observed.
The seeing was average to good,but as the transparency slowly decreased I found it more difficult to and soon had to give up.
The mist in the south looks thicker and brighter white than a week ago,it's a different CM but I suppose the SPH slowly gathers thickness.
A little morning〓mist at the equator.
Some mist or cloud at Tharsis on the PM side: a bright patch in the Arsia Silva region,
and a confused view of what seemed to be a darker patch near Olympus Mons with brighter whiter patch immediately east towards the limb;
too small to get a really good view though.
The NPH looking bluish white and diffuse,no sign of a white cap or a hard edge this evening.
A bluish grey strip of land bordering this to the south.

Still considerably bright preceeding limb, in B more concentrated around the equator.
In the southern hemisph., the great haze patch of the previous days is still present,
apparently a bit widenend, and further
haze emerges from the terminator (21:10, faint effect due to low quality) NPH still visible, but very thin.
Visually, the brightenings by the NPH and the haze in the south seem equally prominent on the small Martian disc.
