Hi all,

Solis
Lacus is at upper left. Some light afternoon equatorial cloud can be seen near
the terminator.

Hi all,
This
morning’s session started off badly with an aborted Mars session due to
terrible seeing. I returned to Mars as the sky lightened, and found some better
conditions.
Olympus
Mons is near lower centre, with M Sirenum at upper right and Solis Lacus is
again coming into view at upper left. I believe it is Arsia Mons that appears
to show as a light spot near the centre.

Thanks
for the comments Roger.
Always
best to have more than one set of images , off course,
so let me see if I can catch Mars tomorrow morning. At this stage low cloud is
forecast, but I always check.
I’ve
seen horizontal clouds in the north like this previously, but Mars is still
small, and I am wary of anything strange near the limbs!
Cheers,

As you
probably know, when a "cloud" is brighter in green light than in
blue, we often think of it as a low-lying fog or ground frost, and of course it
could be both a high cloud plus low-lying condensations. At the Tharsis Montes,
one naturally thinks of it as ground frost on the higher elevations there. One
potentially misleading factor in this simple assessment is that there may be
differences in the processing of green versus blue images. If you are sure that
you process them the same, you can decide the matter for sure.

Hi all,
I was
again trying to snatch data between clouds this morning. Olympus Mons is near
the lower centre, with afternoon cloud over the Tharsis Montes persisting. The
possible northern horizontal "cloud" in green and the bright spot at
lower right (possible dust activity near the northern limb) would need to be
independently verified.
Anyone
interested in the rather unpleasant edge artefact, so often seen with Mars
images, can find more information in a highly informative, interesting and
comprehensive article by Martin Lewis: https://skyinspector.co.uk/mars-edge-artefact/

Hi all,
I didn't
expect to get anything out this morning as there was almost total low cloud
cover. However there were some moments where it thinned enough for me to catch
data. This is another set from single best captures. M Sirenum is at upper
centre, with Olympus Mons at lower left. There appears to be afternoon
orographic clouds over Arsia Mons and Pavonis Mons near the terminator.
Although
I can artificially remove the edge artefact, I am deliberately leaving it as it
is for the time being, so as not to bring in any additional artificial
artefacts.

Hi
It will
be interesting to see when the number of orographic clouds decreases over the
Tharsis volcanoes as the NPH forms over the artic in the Fall season that has
just started.

Hi all,
I had
variable seeing this morning with some cloud interference. The RGB is produced from
the single best channel images. Unfortunately the longer wavelength channels
are severely affected by edge artefact, which is likely exacerbated by the
eastern boundary of Elysium (Phlegra, Trivium Charontis and Cerberus) being
very close to the limb. Olympus Mons is at lower left, with some nice late
afternoon equatorial cloud over the Tharsis Montes region

Hi all,
After
nearly a week of cloudy mornings, I managed to catch Mars this morning, albeit
through extensive moving cloud, with the histogram swinging wildly. AS3! again did a wonderful job of extracting the best data.
M
Cimmerium and Hesperia cut across the upper centre of the planet, with M
Tyrrhenum and Syrtis Minor to their right. Syrtis Major is on the right limb
and Elysium is at lower left. Mars has attained 5" in size.

Hello,
I hope
you all are well. Here is my first sketch of Mars for this
apparition. I managed to see a little detail on the very small disk in
the brief period of decent seeing during morning twilight and shortly after
sunrise. The best view was in IL and with the magenta filter.

A poor

allowed single captures of R, G, B and IR. Aurorae Sinus is close to centre,

Website ... and an Epilogue for
commemoration
Received:
Dear
Friends and Colleagues,
After nearly a quarter of a century, and over 4 years since the end of Cassini,
the official Cassini Imaging Team website ...
http://ciclops.org
... has been recast into its final legacy form and is
retiring. It has been converted from a dynamic site, built, with
every click, one page at a time with information extracted from various
databases, to a static one requiring no on-the-fly computation. What it
looks like today is the way it will look in perpetuity.
This has been a very big task and required my going through the site,
correcting broken links and other mistakes, improving organization, making stylistic
changes, and adding supporting materials. And it required collecting
together a team of volunteers, with skills in php, html, website configuration,
cloud services, and operating systems, to convert and migrate it to the
cloud. The members of the CICLOPS Legacy Team are mentioned
here: http://ciclops.org/webcredits.php.html
(In addition, assistance was freely given to migrate other
software packages that I will be using in the future to write my book.
Yes, there will be a book ... eventually.)
I am very pleased to say that, as a result of a remarkable team effort over the
last 2 months, all done remotely, the site is far better
and faster than it ever was.
To mark this big moment, I have today posted a final Captain's Log,
appropriately called 'Epilogue', in which I remind us all of the intent for the
site when it was first established in 1999, its various components, the highlights
of the Cassini mission, and most importantly for us, the discoveries made by my
imaging team members and I in 20 years of producing the visual record of our
travels to and around Saturn.
It was an extraordinary experience in every way. It is worth remembering.
I hope that, in the future, you visit CICLOPS.org when you wish to recall that
experience and those glorious years traveling Saturn.
Enjoy!
