Mars on Sept. 01 IRGB and IR670nm observations.
Solis Lacus region, Phoenicis Lacus, Noctus Lacus, Tithonius Lacus, Syria,
Tranumasia, Aonius Sinus, Daedalia, and especially Nectar can be seen well.
We have also a very natural view on the Arsia cloud which we seen as a very
soft fine haze.

Here you can find the final observation set of my Sept. 3, session, showing
good detail around the Solis Lacus region. Note especially the circle of
Olympus Mons near the limb, now completely without shadow, as we will see it
always at the time of opposition. Included is also a very small version of
the image, to show visual impressions at around 300x concerning color.
The contrast was a little less visually.

Attached are 2 images from this morning Sept. 4th taken under poor-fair
seeing conditions. The Solis Lacus region shows its different surroundings
well. Note especially the line of Tithonius Lacus (as on the Antoniadi and
Flammarion map,and as Agathodaemon on the map of Schiaparelli), which is
actually a sign of Valles Marineris!
Taken with my 10 inch Newton and ToUcam PCVC750k (IR670-1000nm and color shot).

Here are some multispectral images from the 9th in good seeing. A lot of
interesting detail can be seen.
Over central Chryse a small streak runs NW from Oxia Palus to Niliacus
Lacus which coresponds roughly to the Hydaspes canal. Others may want to
comment. Argyre is interesting showing a cicular outline and dark central
spot. Some weak remainder (possibly of the SPC) remains in the area. A dark
streak is present across Depressiones Hellesponticae. Pandorae Fretum has a
well defined southern boundary. Deuteronilus can also be seen in the early
R images. Also note the weak light channel running through Eos.
In B and G a dense misty NPH is present, and Mare Acidalium can be seen in
places through the mist. Note the dark line bordering the NPH is Blue. Also
in Blue, weak evening mist over Hellas and morning mist over Argyre. A light
MLH is present over Thaumasia/Candor etc.

Here are some images from the 13th in fair to good seeing. Interesting to
note the "hole" in the NPH in the G images. Deuteronilus appears dark in
all filters bordering the NPH in G and B.
In Blue a dusky patch is present where Deltoton Sinus once was. Hellas is
misty toward the evening terminator. Chryse has some light haze which looks
a touch yellowish. Edom also shows a faint mist.
Comments: Morning limb very bright, Hellas area which is about to swing
around on the limb was very reflective and bright. Blue clouds seen on the
NPH - confirmed visually with #38A blue filter.

Last night it was the first really good seeing over the south of the
Netherlands in a long time. I took many IR-and blue images with the
ATK-1HS and some IR and color images with the ToUcam. Here is one of
the IRGB results taken with the ATK attached to a 10 inch Newton at f/60.
The NPC was already large in the blue light and very obvious visually
with a nice cyan color. Visually impressions were excellent, especially
with a 3.6mm Super Plössl oculair at 333x.

I made an observation of Mars on September 14, 2005 (06:30 U.T. (IL/W30)
and 06:50 U.T. (W38)) under average to good seeing conditions (5-6/10, moments
of 7/10). I noted an impressive amount of detail extending between Sinus
Sabaeus and Solis Lacus (on the following limb). Mare Erythraeum appeared very
complex and mottled. I welcome any comments on my observations.

Hellespontus appears dark (3/10) along the south-preceding limb. Noachis
appears shaded to bright (6-7/10). Chalce (?) appears as a dusky (4/10) wedge
extending into Noachis. Pandorae Fretum appears dark to dusky (3-4/10) south
of Sabaeus Sinus (3/10) and Meridiani Sinus (3/10) which are separated by a
shaded to bright (6-7/10) Deucalionis Regio. Brangaena appears a thin, dark
(3/10), curvilinear projection from the north-following border of Meridiani
Sinus. Margaritifer Sinus appears dark (3/10) and wedge-shaped on the CM. Aram
appears bright (7/10) between Meridiani Sinus and Margaritifer Sinus. Oxia
Palus appears as an elliptical, dusky (4/10) albedo feature north of the tip
of Margaritifer Sinus. Mare Erythraeum appears complex and mottled (3-6/10)
following the CM. Aurorae Sinus appears dark (3/10) and wedge-shaped towards
the following limb. The northern border of Mare Erythraeum appears complex
with thin, dusky to dull (4-5/10) projections extending into Chryse-Xanthe
(7/10). Solis Lacus appears dark (3/10) and foreshortened along the following
limb. Niliacus Lacus appears as a dark to dusky (3-4/10) wedge partially
obscured by an extremely bright (9/10) North Polar Hood (NPH). Extremely
bright (9/10) morning and evening limb hazes (MLH and ELH) are noted.
06:50 U.T. (Right image, W38): The South Polar Cap (SPC) appears small and
brilliant (10/10). Pandorae Fretum, Sabaeus Sinus, Meridiani Sinus,
Margaritifier Sinus, Mare Erythraeum, and Solis Lacus are visible as dusky to
dull (4-5/10) albedo features towards the center of the disk. Aram appears
bright (7/10, possible water-ice clouds?). A bright to very bright (7-8/10)
cloud appears to extend between Eden and Tharsis over Chryse-Xanthe. Niliacus
Lacus is visible as dull (5/10) wedge south of an extremely bright (9/10) North
Polar Hood (NPH). Extremely bright (9/10) morning limb haze (MLH) and evening
limb haze (ELH) is noted.

Syrtis Major is central in these images with various projections off it notably
toward Osiridus Pr. The area at NW Syrtis Major looks faded giving it a rather
pointed appearance. Zea Lacus/Peneus are seen inside Hellas. In Blue, a light
haze is present over Libya. An SPC rift is hinted at in Red light.
Image of the large and bright North Polar region cloud or dust storm.....what
is remarkable is the strong concentration of this cloud into what does now
appear to be a possible vortex point of origin.
An incredibly large and bright thin cloud with strong central condensation or
origin point appears just south of the NPC (lower part of image, with SOUTH
UP); the bright feature is especially dominant in RGB or IR bands, suggesting
the possibility of airborne dust.
Seeing was somewhat poor, but the concentration and focus of the bright cloud
is very obvious and well defined at this time.

One set of filtered images this morning between 08:00 and 08:45 UT.
Details are marked on the image. The area I find of interest is along the
border of Sinus Meridiani and Chryse, following the slender curve of Oxia
Portus. There is a bright area in the red image, inside of the limb processing
artefact. Potential cloud/dust?? This is probably of no significance, but
I wanted to send it out ASAP just in case.
Here are some images from the 21st. Very good seeing before the fog arrived.
Some interesting hazes visible in G and B images. Some yellowish haze visible
around Hyblaeus. Also and evening limb cloud visible over Aeolis. Hazes over
Hellas and Libya again. NPH is thick but partially transparent.

At this location its very rare to get more then 2 or even 1 nights with good
seeing. This rule was broken now,and the fourth day gave even a longer period
of exellent seeing. Therefore I concentrated on imaging the Huygens crater,
which could already be seen easily live during capturing on the screen!
The crater is visible in the image as a bullet.

Boreo Syrtus and Protonilus,beside of the much more contrasty Nodus Alcyonius.

Here is the finest result of my observing session SEPT 22, a high resolution
view of the Syrtis Major region. Featured in black & white high contrast
for maximal presentation of subtle contrasts and detail. This might be my
best resolution image of Mars so far.
Time: 04:36 UTC

Here are some additional images from Sept 22,
Taken at 05:02 UTC. (color & bw version)
Good detail in Syrtis Major and especially Lapygia Viridis and
Deltoton Sinus.

Here is an LIRGB version of the SEPT22 04:57 UTC image, with even better
contrast resolution of the Mares.

Here is the final re-processed color result of my 22 September observation of
Mars. Mars was here only 16.67" at that time. It's a pity that I had no good
seeing this recent transit of Syrtis Major with 20".

Observing notes:
-The SPC is small
-The northern area of HELLAS is bright ?1)
-The NPH can be seen
Mars under fair skies, showing the continued bright north polar hood (?) but
with an extended southward streak at the following edge (right) terminator;
this is not a processing artifact, as the streak is conspicuous both with
visually and on raw images. Some longitudinal separation on the southern side
of the bright bluish polar cloud is visible.
Very likely, with the hurricane RITA headed right toward Arkansas and expected
to stall out with torrential rains for about 5-6 days beginning late Saturday,
this will be our last effort for a while; at least Petit Jean Mountain is some
1300 feet above the nearest flood plain.

After a rare period of 3 days excellent seeing, it was still clear last
night but the seeing turned to standard poor-fair, though it was usable
to take some images. Nodus Alcyonius is present very well. Hellespontes
Montes is even very nicely visible, also note the obvious brighter
northern-part of Hellas.

Attached is a set of blue light images taken on Sept 26 at 04:44 and 05:07 UTC
Seeing was very poor in this session, and only the blue light images were
acceptable. Although no sharp edges, they show some interesting detail.
There are structures visible in Mare Simmerium, and there is an obvious
bright spot with round shape at the terminator, approximately in the region
Zephyria.

I made observations of Mars on September 28, 2005 (06:30 U.T. (IL/W30) and
06:50 U.T. (W38)) under average seeing conditions (5-6/10). Brief moments of
steady seeing (7/10) allowed me to note much detail over the Martian disk,
especially over the southern hemisphere. I welcome any comments that you may
have on my observations.
Date (U.T.): September 28, 2005
Time (U.T.): 06:30 (left image) and 06:50 (right image)
CM: 243.0 (left image) and 247.8 (right image)
Ls 296.5, De -10.5, Ds -22.0, Dia. 17.5", p 0.93
Instrument: 9-inch (23-cm) F/13.5 Maksutov-Cassegrain
Magnification: 248x and 344x
Filters (Wratten): 30 (magenta) and 38 (blue)
Seeing (1-10): 5-6 (moments of 7), Antoniadi (I-V): III
Transparency (1-6): 3-4 (hazy)
Notes:
06:30 U.T. (Left image, IL/W30): The South Polar Cap (SPC) appeared very
small but brilliant (10/10) and surrounded by a dark (3/10) collar (Mare
Australe). Mare Cimmerium was prominent (3-4/10) and mottled preceding the
CM with Tritonis Sinus on the CM itself. A section of "Valhalla" was visible
(5/10) to the north of Mare Cimmerium towards the preceding limb. Scamander
was visible along the southern border of Mare Cimmerium (it's base (Scamandri
Sinus) was darker (3/10) compared to the rest of the feature (4-5/10)).
Electris, Eridania, and Ausonia appeared shaded to bright (6-7/10) and finely
mottled. Mare Chronium appeared dusky (4/10) along the CM towards the south.
Hesperia appeared as a bright to very bright (7-8/10) angled wedge on the CM
between Mare Cimmerium and Mare Tyrrhenum (3-4/10). Syrtis Minor was visible
as a dark (3/10) wedge following the CM. Mare Hadriacum was visible as a dusky
to dark (3-4/10) eastern (preceding) border of a very bright to brilliant
(8-9/10) Hellas. Iapygia Viridis was visible (4/10) adjacent to an extremely
bright (9/10) morning limb haze (MLH). Syrtis Major appeared as a dark (3/10)
wedge adjacent to the MLH. Moeris Lacus (4-5/10) was visible projecting from
the preceding (eastern) border of Syrtis Major. Libya appeared very bright
(8/10) possibly due to clouds or haze. Aeolis, Aethiopis, and Aetheria appeared
bright (7/10). Elysium was very bright to extremely bright (8-9/10) along the
north-preceding limb. Pambotis Lacus (3/10), Eunostos (4/10), and the Hyblaeus
Extension (3-4/10) were visible along the following border of Elysium. Nodus
Alcyonius was visible as a dark (3/10) oval following the CM. Utopia was
partially visible (4/10) south an extremely bright (9/10) North Polar Hood
(NPH). An extremely bright (9/10) evening limb haze (ELH) was visible as well.
06:50 U.T. (Right image, Wratten 38): The South Polar Cap (SPC) appeared
brilliant (10/10). Mare Cimmerium and Mare Tyrrhenum were visibly dull (5/10)
with little other detail towards the center of the disk. Syrtis Major was
visible as a dull (5/10) projection towards the following limb. Libya appeared
very bright (8/10). Hesperia appeared as a thin, bright (7/10) wedge just
preceding the CM. Hellas appeared very bright to extremely bright (8-9/10)
with very bright (8/10) projections extending from it's preceding border over
Ausonia. Extremely bright (9/10) morning and evening limb hazes (MLH and ELH)
were visible. the North Polar Hood (NPH) appeared extremely bright (9/10) as
well.

Seeing poor occ fair (Pickering 2-5.)
Transparency variable with frequent low clouds (cloud - 6.0mag.)
No wind. Heavy dew.
Alt=50-53 degs.
Mars under very poor conditions with heavy dew; some interesting haze or
clouds appear in the southern quadrant of Hellas (lower left, seen best in
RGB image) as well as possible haze on eastern (celestial) side of Syrtis
Major. Note that indication of separation in SPC is evident, and very thin
wispy North Polar cloud persists, but not in widespread polar hood as evidenced
in previous dates and other longitudes.
