Hi all,
Image set from yesterday afternoon looking down on the
Elysium region.
The B data was again poor.

Hi all,
Another late season attempt at Mars after a recent cold
front has moved through.
As can be seen, the G and B were a challenge.
Elysium is just to the left of centre, with Mare Cimmerium at upper left. Syrtis
Major is on the terminator at right.
I think it is the Nodus Alcyonius/Cassius/Utopia region that is so prominent at
lower right.
Best regards,

Hi all,
A rather informal submission.
Over the last week I have had a number of attempts at Mars,
but have been unable to put together either a full data set,
or the B/G were too poor to generate an acceptable RGB.
But having put the initial effort in, I thought I should at
least share what I could.
I appreciate that the format may not be acceptable for some
of the databases, but circulate for interest nonetheless.
Mars was 4.3-4.2” during this period.
Best regards,

Hi guys,
Some excellent seeing on the 23. The AWO S Trop spot is visible, as well as a
chain of dark spot.
French observer Jean-Paul Oger has made a polar map of the southern hemisphere
and his work shows that the ondulating South tropical
region has a decagon regular shape ! See here

Hello.
I am sending over this evenings Mars images in below
average seeing.
But there is a dramatic limb brighting
visible on the image in red light and
also was very obvious on the monitor dispite the
seeing conditions.
Also on the morning limb is some morning mist in the Tharsis area.

Hi all,
I tried a twilight session yesterday afternoon/evening.
Sinus Meridiani is above centre
with Mare Acidalium to the lower right and Mare Erythraeum at upper right.
Sinus Sabeus extends to the left
of Sinus Meridiani.
The bright Arabia/Moab/Eden regions extend across the lower
left quadrant.
The B data was not particularly good, so it is difficult to
say whether the bright feature above the NPC is dust or cloud.
There appears to be morning cloud along the terminator.
I was pleasantly surprised with the conditions as there was
severe Jetstream

Hi all,
Mars is becoming more challenging, and I have been prevented
from submitting images for a number of evenings by very poor B data (there was
strong Jetstream) Last night was a bit better.
Niliacus Lacus
and Mare Acidalium are below centre, with Margaritifer Sinus extending down towards Oxia to the left of centre. Sinus Meridiani
can be seen on the left limb. Mare Erythraeum extends
across the upper portion of the planet.
Cloud remains over Tharsis.

Hello !
Firsts Saturn images of the season -
and the first in almost 2 years.
The planet is largely olive yellow
currently, the blue has completely disappeared, although two pink belts can be
glimpsed on the northern hemisphere.
Thethys is in transit in all images.

About
This is a demonstration of morning clouds. They are
extensive over the right half of the visible side of the planet, obscuring Mare
Sirenum and the Amazonis /
In the blue clearing study that I published in JALPO during
the last year, this image would have been excluded from the study because of
the obvious clouds. Having said that, it appears likely to me that the
blue clearing phenomenon is due to subtle clouds, which explains why all of Shanos's blue images with contrast ranges outside the
normal distribution of contrasts were in northern spring (i.e., the cloudiest
season on Mars). However,
To be clear, the blue clearing study of 63 of Greg Shanos's images involved rejection of all the images in
which clouds were suspected by me. The finding of 6 outliers showing high
contrast in blue suggests that I was unable to find clouds (in order to exclude
those images from the study) in those with very subtle clouds that had
measurable brightness that was not evident by simply inspecting the images.
I don't think that an extraordinary explanation such as the
loss of atmosphere from Mars during the last year is reasonable.

Hi
There is one image, the blue image that blows me away with albaedo features. I think that if one scans through
images in the
current apparition, there will be found a number of full and partial "blue
clearings" The
remarkable thing
is that some of them cover the whole face of Mars just like
I think this all has to do with the density of the air mass
overhead. The higher the density results in less albaedo features .
The lower the density the more albaedo features.
I think we all know that Mars is gradually losing its
atmosphere to the solar wind. Adding to that last year two CMEs
blasted Mars.
Does anyone have any thoughts about all of this? Thanks.

The view is centred on Tharsis, with the Valles Marineris can just be seen to the upper left of centre,
with Solis Lacus near the upper left limb. Mare Acidalium
and Nilokeras are toward the lower left.
Cloud is visible in the proximity of the Tharsis
Montes, whilst there may also be cloud near the NPC.

Hi all, here's an image of Saturn from this morning captured
in a short period of steady seeing with minimal jetstream
interference.
13 images were combined in Winjupos
spanning 30 minutes. Some faint structure can be seen across the disk, with Dione showing above the ring on the left.
