To an image of Mr. Anthony Wesley,the state that a cloud
covers up in the Argyre basin is recorded. This cloud comes out
clearly under S P hood. With this image,states of water ice
cloud are recorded very well. I can confirm the state that is
passed to the east and west into a line form when I see it
carefully. In addition,two ring-formed clouds are seen in the
north of Meridiani. It may be the real nature of the cloud which
I saw in March.
With this image,I see that the domain with a few clouds
appears on a part located outside of S P hood. The place is
the position of Mare Erythraeum.
In Elysium,a child was recorded not to make any cloud from
an image of Mr. Clyde Foster at around 9:00 a.m local time.

It was almost totally overcast when I got up,but was rewarded as the clouds started breaking up,and I was pleasantly surprised that the seeing was reasonable. Possibly the "blandest" view of Mars,centred on the Amazonis region. In processing a few of the images that I took over a number of minutes,some of what I originally considered to be noise in the Amazonis region,turned out to be subtle albedo features. I will have a go at trying to put a GIF together. The two brightish features just south west of Olympus mons(Gordii Dorsum?) are quite clear. I am a bit intrigued by the row of dark dots just below the south polar hood. They aren't shown prominently on my globe or maps. Also by the darkening of the south polar limb. Is this purely due to the angle of Mars relative to the sun? I assume the dark feature cutting across the north polar region is Olympia Planitia? Looking forward to a bit more detail coming into view in the next week.

The north pole is visible at top left and clouds can be seen across the disk.
The colours are better today,no terrestrial clouds interfered today so a good colour balance was easier to achieve than last time.
