Hi all, here are some Jupiter images. The seeing was good but there was
some haze in the sky, the UV and integrated images have been taken through it
unfortunately.
On another
topic, please note that since december
I have taken the responsibility of the Mars Section in the SAF (which
coordinate also the observations of Venus and Mercury). I'm succeeding to
Daniel Crussaire.
Best wishes,

Hi all, a great number of people are
legitimately expressing their concern about that the dark arc band could be an
artifact. I have been also surprised by the look of the images, nonetheless
it's definitely apparent already on the raw images - here you have one that is
taken from the last UV capture. Moreover I find hard to understand why an artifact
would reproduce itself exactly the same on six different images... So as far as
I know for me it's a real feature, but if someone has more data please send it
to me !

Hi everyone,
For these images,
the seeing was very good at the beginning when I took the UV image (200 x 2
sec.), which is the sharpest I have obtained so far.
Seeing then noticeably degraded. Nonetheless, there is again a possible
white temperate spot (arrowed in the green image) at III = 245°.

Hi all, Here are my
first Mars images since December. Seeing was good. Elysium is caught in R and
IR, but the SPC is not apparent. I have also tried to secure an UV image for
the first time thanks to the ATK-1HS (200 x 1 sec). It enhanced greatly the
white clouds, but oddly Mare Tyrrhenum looks still visible!

Hi everyone - some recent Jupiter images. On january 29th, it was again an unexpected clear night (after
our first snow episode here in six years !), but
seeing was again not good. I stayed in the garden with the 7" newtonian. On january 30th, I have used the C14 and an accessory to
reduce the focal length (what's the word?) with the 2x barlow,
for the UV images. But as seeing was only fairly good I have taken all the
images with this setting. The UV images are taken in 3 mn,
150 raw frames each with 0,5 second exposure.
The STB dark spot
seems to be in conjunction with the GRS ; very dark in
blue, it's faint in IR light. Note that it has been caught in UV also. The last
UV image may show that big white spot imaged in UV by Tomio Akutsu
on january 25th (CM I = 321°),
much fainter; it does seem to corresponds to a plume here and not to a base
festoon but that's only a possibility.

2nd 2004
Hello everyone : I have one hour or two of good
seeing this afternoon to try imaging again Venus. This time, the details in UV
have a more classical shape, with white "polar cusps" much like
Frank's images of yesterday. As my technique was exactly identical as the three
previous attempts, I find that the idea of a technical problem on january 29th is becoming harder to
sustain... Apart of this, the W47 filter + IR cut confirms the pattern of the
UV dark markings, with less contrast. The blue filter seems to faintly show the
darker ones. In IR, some faint dark shadings may be
visible again (horizontally).

Hi all, here are some recent images taken with
the 16" newtonian of
Gino Farroni, the Jupiter SAF coordinator - seeing
was poor/fair. The aspect of the STC following BA is remarkable...

Hi all, These images
show one of the white spots (here at L3 = 252°). I've finally obtained the quality I was more or less looking for in UV
(thanks to a lower focal length, bigger scope and the absence of a correcting
plate!) : 600 raws have been
stacked with an exposure of 0,5 sec. each.

Hi all, one small
Mars from yesterday evening. Solis Lacus is seen as well as the other markings
in the region.

Hi everyone, Seeing was fair/poor on february
10th and I have then used a focal reducer. The steadiness was much better in
IR, as expected, but also in UV, less expected, and that's something I have
noticed on Venus also... I may have a "misalignement"
of a bright UV patch and dark base festoon in IR, such as in Tomio's images in the first UV and IR images, but not on
the seconds I think.
Best wishes

Hi all : some Saturn images on february
9th. The spot at 250-260° looks to have disappeared: it's not visible in the
second LRGB image even at very high contrast.
The UV image has
been made with more than 500 exposures (2 seconds each)
