This image was taken in very poor seeing and transparaency. It features Terra Cimmeria and Terra Sirenum.

Conditions were average,slightly blurry and variable,never very good.
・The dust lane is certainly less striking this evening,and in very poor seeing not all that obvious,but it still snakes across〓
the brighter land to the SW of S Lacus,as it has the past few nights.
・The area of dust on the SE limb at Argyre was still very bright indeed,with streaking visible,〓
the brightest〓part nearest to the SPC again rivalling the cap in intensity.
・Xanthe,on the evening limb was also very bright,and showed streaks running E-W
・The evening limb was brighter with dust tonight as more of the storm rotates into view.
・Agathodaemon was seen softly,with a subtly brighter streak to its North (Valles Marineris).
This brighter lane of dust ran all the way to the limb,wider the further East it went,separating Aurorae Sinus from Mare Erythraeum.
・SPC normal.
・NHP well seen,displaced to the West,and I still feel less wide than a week ago,but not a dramatic change.
・A little morning mist but only in the North.

some reasonable seeing last night,
here's a colour image of Mars showing the current dust storm which is covering much of the visible features at this longitude.

I managed to find a short,unexpected gap in the recent rainy conditions for this view of Mars yesterday evening.
It shows the western regions of the recent extensive dust storm,and to me,it appears that this region may be starting to clear.
However,dust is still clearly seen over the Argyre region and extensively across Mare Erythraeum and possibly Chryse.
Ascraeus Mons is prominent extending through cloud at lower right.
With almost saturated conditions,the hair dryer had to be put to good use.

The seeing was average and the transparency fair.
[Jean Jacques Poupeau : Pecqueuse France]
The seeing was poor.
[Jose Alberto Berdejo:Zaragoza Spain]
[Joaquin Camarena:Spain]
relatively good seeing for this image of M. Cimmerium/Elysium region.

We had some unusual conditions here last night- the seeing was around AI-II for the entire session.
I began observing Mars at 1809UT and finished at 2336UT and even though Mars was getting lower by then,the conditions were still very good!
As a result I managed to make four drawings showing the current dust storm activity.
I used powers of x300,x375 and x600 and observed some interesting features on the disk:
・SPC is still bright,and white in colour.
・In drawing 1 it is clear that there is a lot of dust in Erythraeum and in Argyre.
There seemed to be a bright core on/near the Argyre region.
・The dust lane passing diagonally through Solis Lacus seems to have faded somewhat- interestingly some albedo features seem to be darker,
Depr Pontica and Aonius Sinus seemed quite dark.
In drawing q parts of Erythraeum can be seen through the dust clouds,and the clouds themselves were a lovely orange-yellow colour.
・The streak in Ganges was present and Candor seemed a little brighter.
Interestingly,the brightness from Candor seemed to extend in Tharsis and Uranius.
・I also observed some fine markings in Tharsis,Uranius and Ulysses which I have never seen before (or at least never this clearly)
・Later,Sirenum and the eastern edge of Cimmerium were seen.
Sirenum had some darker sections,Phaethontis and Electris observed but neither region particularly bright.
・More fine shadings observed in Amazonis,and Zephyria.
・NPH present but I had the impression it might not have been as extensive as usual.
This was probably the longest session I have ever spent on Mars!

Another night of bad seeing. But the storm motivates to image!

An image from 22nd Nov,showing the spreading out of the dust storm (at about the 10 O'Clock position on the limb).〓
Some hints of interesting detail/colour around Olympus Mons.

Seeing was superb on the 22nd.
A bright transient morning cloud is visible on the morning terminator in deep blue and UV light.
I have not been able to find another occurence of such a feature on another day.
[Christophe Pellier Bruz City,France]
Nice seeing that night,giving a nice view of Terra Sirenum in the souothern hemisphere,the austral cap,and North Amazonis Planitia and the extent of Olympus Mons,and its caldeira.
On blue images a high altitude feature can be seen.
[Marc Delcroix Tournefeuille,France]
Average seeing for this session. Mare Cimmerium on view. Elysium toward top.
