This

Regarding
the parallel streaks in the Northern Hemisphere in Tsuyoshi Arakawa's composite
image and in his IR image, it appears to me that his camera was oriented so
that its horizontal dimension corresponded to the the RA (east & west)
direction on the sky. He rotated his image nicely during processing, and this
makes the streaks appear to be not horizontal. If you look carefully at
his red color-component image, you will see in the Southern Hemisphere another
set of streaks perpendicular to the more prominent ones in the Northern
Hemisphere. I think that they are a sensor line
artifacts.
This is
a fine image, with good detail, and reveals much about the dust storm.
I do
not feel comfortable talking about artifacts in images, but I offer my
assessment because it was brought up already. I hope that it is not interpreted
as negative criticism, for I try to be positive all the
time. Every image has artifacts, and the main challenge is not to eliminate
artifacts but to successfully image that which is not artifactual.

Hi
Richard and Roger.
It
looks like the Western edge of the dust clouds has retreated Eastward.
But now
it looks like dust clouds cover most of the visible Northern Hemisphere.
The
wave pattern could be artifacts but I don't think so.

Hi all,
A quick
image set from this morning. Although all the excitement (dust storms in and
N/NW of Valles Marineris) has already rotated into the dark, itfs always
worthwhile (as Richard McKim has mentioned to me many times) keeping an eye on
what's happening elsewhere.
Olympus
Mons is just in view at lower left. In the IR there is a feature SW of OM that
looks a bit unfamiliar (Eumenides region?). I'm also afraid this may add some
fuel to the fire of the recent comments on the colouration of the SPC. I
fully appreciate that I am still learning like a hound dog, and can only
process as best I know how at this stage. Plenty still to learn, and I might
just have to have a look at Damianfs latest tutorialsc...
On a
more personal note, I may be putting out a few less images than normal, as it
looks like I may have picked up another chest cold (all rather disconcerting
given what's happening in this area and the country), and I am being
ultra-conservative in terms of getting plenty of rest and continue to
self-isolate as best I can. Hopefully come out the other side quickly and be
back to full speed for the Jupiter and Saturn oppositions in July.
Take
care and best regards,

Hi,

I would
be a bit careful about reading too much into the colour in the SPC.
This
was a quick process at the end of a very long and intense day of image capture
and processing. I was pretty exhausted!
I would
check other comparable images to see if they are similar.
However
the recent dust activity is very real and interesting, if not the most popular
develop for the Mars community!
I
should be able to see the area sometime mid-end of this coming week.

The shadow

Hi allC
At
least at the start of my session, I had some reasonable seeing this morning and
I was able to capture this image set of Mars, before the seeing dramatically
degenerated for my Jupiter session.
This
image again seems to indicate that there is some dust across the SPC although I
do not know if this is atmospheric or deposited. My feeling is that it may be
deposited. Looking at mine, and others recent images,
I also have the perception (I could be wrong....) that there may be dust haze
across the planet. Possibly some residual from the dust activity we have seen
over the last few months?

Dear
all,
My first image of the Great Red Spot this year. This
was made from a single 1 minute video, the best of three. Some interesting
details, including the eeyef shape of the spot, the split in the SEB preceding
it, and the incomplete belt N of the SEB (is that classified as part of the
SEB?)

Hi all,
I
stopped over briefly at Mars on the way out to Jupiter this morning.
There
has been some recent discussion regarding possible dust activity on the SPC,
and this image set seems to give some credence to this. Ifm not convinced I
have made the most out of the RGB- itfs a bit dark.

Dear
Jim,
Looking
at similar images and the degree of processing necessarily used, the bright
belt north of the dark collar is surely a processing artefact, not dust
related. You will see the sharpening was enough to bring up the limb artefact.
I have
noticed this brighter belt in images over several months, which suggests that
it is not a real feature. But I think that if you look at the cap itself you
might detect a slight yellow or orange tint, which I think is suspended dust.
Have a
look at the image by MacNeill a few days earlier where there is a distinct
curved dusty marking near the dark polar rift. Such a feature was seen in 2003.
All
good wishes

Hi
Sublimation
winds from the SPC continue to be the main event. The dark collar shows the surface
that has been blown free of dust and immediately North shows a bright collar of
the new dust deposits.
One can
estimate that the depth of the evacuated dust layer was less than 3 or 4
meters.
Thanks
for your high-res images.
Good
seeing,

Hi allA
Valles
Marineris at centre right with Solis Lacus at upper right. The familiar "3
leaf clover " structure around Aurorae Sinus can be
seen at centre. Nilokeras is visible at lower centre. The SPC looks quite
complex at this stage.
