Mars Images — MarsWatch 2005
Wednesday, 21st of September 2005
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.

Here are some images from the 22nd - my best session so far this apparition.
Good seeing allowed some interesting details to be noted.
There seems to be some notable yellowish areas present, especially near Elysium
and Hyblaeus. The areas show up well in Green and RGB. Some fine detail across
Mare Cimmerium and Hesperia. The NPH shows is again partially transparent with
a thick northen part.

Sept 22 Mars observing session; very good-exellent seeing/good transp.
Again a very succeeded session, thanks to exellent moments of seeing, even a
little better then the previous session of Sept 21. The regions northern of
Syrtis Major stand out well.We see clearly; Casius(southern part of Utopia),
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.

Moab & Aeria brightest regions. Thin, faint line on S border of NP Hood. In
W38A blue filter, NP Hood as bright as morning limb haze. Did not see evening
limb haze. Hazy &/or cloudy area noted over S Hellas and area F. In W58 green

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.

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.
