Paul G. Abel
We had a brief clearing early this evening and I was able to make an observation of Mars (attached).  Seeing was fair and I mostly used a power of x470 to observe the Martian disk.  The main points of the observation were:
・Brilliant white clouds visible over Thyle and extending down into electris.
・Mare Sirenum visible although not as dark and prominent as neighbouring Mare Cimmerium
・A vague dusk streak seen in Amazonis.
・Vague shading in Diacria.
The dust storm:
・This was quite a difficult to see- there certainly didn't appear to be any bright orange clouds or any sign of active orange clouds.
・I did get the impression that dust had been laid down just south of the north polar cap.  This took the form of patches of dusk and in the better seeing,dusty streaks.
・The NPC seemed less prominent and the Lowell band was very difficult to see.
・It certainly seems to me that the storm has ended and there are dust deposits visible in Acadia and near Diacria.  Such deposits arfe probably only visible in large telescopes under good-medium conditions.

Observation made mainly searching for the polar dust storm,which seems quite weak or missing at all here.
