The seeing looked steady visually last night, but
on-screen it was rippling very fast at a small scale (not surprising for 27º
altitude). Three sequences of RGB were captured, and all combined for a 14 minute
run, interspersed with I captures. This is the first image I have produced
using the PierroAstro dispersion corrector in the imaging train.
There's no evidence of any spots, though Encke is
faintly apparent.

Here's
an image from some bloke named Cassini who clearly has a pretty
good scope... showing what looks to be the same dark spot that we've
been seeing on Saturn in recent weeks.

Hi
all, here is an IR image from March 26 in poor seeing showing the compact dark
spot in Saturns north. I've added an animation of 2 frames to make it
easier to spot, it's just past the central meridian on the first image.
There
is also a light spot up close to the north pole that can be seen in the
animation. I've enhanced the brightness of Tethys to make it more visible and
assist in image measurement.

Hi Guys
A rare and very welcome sunny day but with poor
seeing .
Higher res shots, well 80 inches fl on the Flea 3
1/4" chip, were not very encouraging, so armed with plenty of blue sky a
full disc montage at 40 inches fl seemed a good idea.

March 11, 2013
Dear Friends and Colleagues,
And so begins the end...
Cassini's very last targeted flyby of Saturn's moon, Rhea, occurred this past
weekend, and images from that event are now on the ground and available for
your discerning examination at ...
http://www.ciclops.org/view_event/190/RHEA_REV_183_RAW_PREVIEW
Take a good, long, luxurious look at these sights from
another world, as they will be the last close-ups you'll ever see of this
particular moon.
Our mission at Saturn has been ongoing for nearly 9
years and is slated to continue for another 4. Targeted flybys of the moons
Dione, in June and August of 2015, and Enceladus, in October and December of
2015, are all that remains on the docket for detailed exploration of Saturn's
medium-sized moons.
We're nearing the end of this historic
expedition. Let's enjoy the finale while we can.

Re: Words missing in CMO 407

9 March 2013 at 06:31 JST
Dear
Masatsugu,
I will be able
to write a note for CMO 409 (but so with a deadline around 15/20 april). It
will be about the "escaping cloud" from the Hellas basin as seen in
march/april.
This will be a small introduction about the whitening
of Hellas (the two being linked, as far as I can see now) that would be
described in a following note (for 410 for example).
Then I would have one or two last notes to write (for
the 2012 apparition, maybe I have some other special ideas) :
1) Something about the frostening of Argyre, but I'm
not sure so far tobe able to conclude this one, maybe images are not resolved
enough, I will see
2) A note about the white patch observed at the end of
may north of Arcadia, because it may be a first sign of "polar
cyclone" activity.

Hi all, seeing was not quite as good this morning, but still
a reasonable image of Saturn. I was careful with my colour balancing to get the
rings white, so this should be a close approximation to the correct colours.
The polar hex is visible, as are a few small storms across the disk.

RE:

Dear Masatsugu,
Thank you for the kind words. We have traveled
many miles together since we first started to correspond in June 2001, and I
have learned a great deal from you. I am always very thankful for your
friendship, and hope the nausea and vomiting have now resolved. Were they
due to some medication, or perhaps from overtiring yourself? In any case,
I hope you are feeling well again.
I shall never forget the romance of our
travels to the Japanese Alps and to Noto together, and only regret my attempt
to reciprocate your kindness was compromised by the intrusiveness of a
difficult person. I also wish we had had more time together in Paris and
Meudon. I was able to visit (with Francis Oger) the Juvisy Observatory
again last year, and though the chateau of the great Flammarion remains in a
reprehensible state of disrepair, it is at least good to see that Flammarion's
refractor is restored to working order and I was pleased that we were able to
obtain some impressions of Mars with it on a very bitterly cold night.
Meanwhile, I hope never to be found guilty of the *floccinaucinihilipilification* of the classical Mars. (I just learned this word, which is said to be the second longest word in English; it basically means to discount, to undervalue, to be dismissive of something. I couldn't resist using it here.)
In about a month, I will travel to
Rochester, Minnesota (home of the Mayo Clinic) to give a talk for the
Astronomical League on perceptual issues in astronomy, and on the way plan to visit
Carleton College (where Popular Astronomy was published) to look up W. H.
Pickering's articles on Mars from 1913 on, and also to pay my respects to
the homestead nearby (at Nerstrand) where Thorstein Veblen ("Theory of the
Leisure Class") lived for a number of years. After this I hope to
write up a little piece on W. H. Pickering for you.
As you know, Pickering and Lowell were
great chums early on. However, they both very strongly
individualistic and shared an interest in similar problems; this made them
potential rivals. After Lowell perceived that Harvard College Observatory
was trying to take over the "Lowell expedition," he was unable
to trust that William would remain loyal to him and not to his brother.
But there was also the fact that Lowell was a follower of Herbert
Spencer's doctrines about evolution, and believed that it was inevitable for
planets to evolve from young globes (like Uranus and Neptune) to middle-aged
globes like the Earth to finally dead corpses of worlds like the Moon.
William at the same time was making observations of changes in lunar albedo
features (e.g., the "Gardens of Eratosthenes") that led him to
think that the Moon was both geologically and biologically active, and this did
not fit the Spencerian scheme at all. Both of these men followed their
later careers in parallel, with hardly any reference to one another's work.

All,
Here is an image of Saturn from this morning in very good seeing from my

spot at mid north latitude near the central meridian, and the polar
hexagon and surrounds. Many other faint cloud features are also visible
across the disk.

Morning Star at Saturn: Cassini
Sights Venus
Received;

March 4, 2013
Dear Friends and Colleagues,
Every so often, our cameras on Cassini digitally
record, either
intentionally or incidentally, other celestial bodies besides those
found around Saturn. Today, the Cassini Imaging Team is releasing a
pair of images that did just that.
Venus, a lovely shining beacon of light and Earth's
`twin' planet, was
recently sighted amidst the glories of Saturn and its rings.
Go to ...
http://www.ciclops.org/view_event/189/Venus_in_the_Distance
... to see these wondrous beauties for yourself.
Along with Mercury, Earth, and Mars, Venus is one of
the rocky
"terrestrial" planets in the solar system that orbit relatively close
to
the sun. It has an atmosphere of carbon dioxide that reaches nearly 900
degrees Fahrenheit (500 degrees Celsius), a surface pressure 100 times
that of Earth's, and is covered in thick, white sulfuric acid clouds,
making it very bright. Despite a thoroughly hellish environment that
would melt lead, Venus is considered a twin of our planet because of
their similar sizes, masses, rocky compositions and close orbits.
Think about Venus the next time you find yourself
reveling in the
thriving flora, balmy breezes, and temperate climate of a lovely day on
Earth, and remember: you could be somewhere else!
Enjoy!

sky the seeing was quite good with a little streaming and ripple.
The longitude is the same as the last set I put out ,
Interesting to compare.
vastly different EZ, this set appears to show a

Dear Bill,
@This
time I am deeply moved by your gwell-planned programh of stimulation therapy to
encourage our irreplaceable Masatsugu in his failing health, and to reactivate
CMO/ISMO with hosts of pending problems such as the chronic shortage of
writers/analysts, uncertain successors to the present editorial board, and
etc.,etc.c. You are certainly an admirable psychiatrist, as well as an
exquisite astronomy historian!
I remember your writing in your LtE the
other day that my ARGUS essay might offer a more optimistic assessment of the
situation than your ones. Actually however, I am rather (not quite) pessimistic
about the future of CMO/ISMO. CMO is, as you know well, an unprecedented and
probably the last singular field which had been created some thirty years ago
by Masatsugu MINAMI as an antithesis of the previous defective
observing/analysing systems of Mars, with which the dream of well-planned
program of classical Mars observation finally came true, to which visual/digital
observers world over could have been submitting their records to find their
raison d'être promptly. It's astonishing (and it feels unstable at the
same time/on the other hand) that the integrity of the Martians' Shangri-Laish
zone have been preserved practically solely by Masatsugu, an unprecedented and
presumably the final PURE MARTIAN/visual sketcher on this blue planet. As for
your phrase in your Night Thoughts essay Part One, gCan replacements even be
found?hc Can't at all, I dare say for now. So, I believe, we have to be
confronted with some changes in the system of CMO/ISMO in the near future.
In my future essay I'm going to classify
the astronomers (both amateur and professional) constitute the CMO/ISMO
according to the motivations of continuing their observations to seek ways for
the individualistic glonersh to coexist peacefully and fruitfully as have been
proven unimpossible by Dr. Masatsugu MINAMI.
