CM 10,so Sinus Meridiani and Margaritifer still heavily obscured. Better seeing is projected by Meteoblue in coming days,but we shall see.
Mars midnight session last night,with what is meant to be Syrtis Major central,and Hellas basin upper central.
The IR definitely seems to cut through the dust,at least to some extent.
The SPC is heavily affected by the dust,and there is some finer dust detail on the bright section of the cap.

Images were poor but a relative hole into seeing helped to produce the present report.
Still very low contrasts on features assimilated to ghost features
but with a relative contour which correspond to the known formations.
Syrtis Major is not fully occulted,general contrasts can be stated less than 5% except
on the dark border of the polar cap more vivid.

Still very active dust clouds at these longitudes.

Seeing was better on the 28th.
I took a very similar longitude on the 29th (so that was a bit of a waste of time).
Clearly Sinus Meridiani is now visible.
Itfs true however that IR images like this donft represent the visual view accurately.
I couldnft see Sinus M visually.
The dust scatters the long wavelength of the IR less,
and then therefs some sharpening applied; how much,
and so how visible to make the contrasts,is a matter of judgement.
But I try to maintain a consistent process from night to night.

Very poor conditions so took a quick image set for the record.
This shows the Chryse hemisphere of the planet - not that you would know it given everything is covered.
Dust across the SPC also.
