December 14th, 2003.
Kumamori observed the figure of the dust cloud in Japan in the daytime.
It became the earliest observation record in Japan. The state that a
dust cloud spread out in the west in one day was recorded with this
image. The point of the dust cloud which grew in the north covered
Solis lacus(90W,-25). The dust cloud which spread out in the south
diffused around Foelix(100W,-43). Most of the Japanese observation
people record a dust cloud in afternoon limb. The image of Syrtis
major(290W,+10) which it knows well has been sent from Christophe
Pellier. But, a dust cloud wasn't seen for this image. D.C.Parker
observed a dust cloud from the front. This is the important report
that it knows the extent of the cloud. It knows the state that the
whole of the dust cloud is moved to the south well.

Mars was photoed after a long time.
Seeing was not good.
It had a appreciation of the power of Registax.

土曜に引きつずき、南中過ぎてもシーングは良かったです。
南極冠もしっかり確認できます。皆さんも感心されている通り

ということは木星・土星・金星と同じ年中観測が出来ることに
成りますね。

Hello everyone : I have observed Mars tonight in a few lulls, and did manage
to catch two images of the Hellas hemisphere (IR and Blue). It seems that no
dust is visible there, the strange aspect of the Hellas basin may be due to
low resolution only. Images made with a 355mm SCT.
I will possibly have more chance to image Mars this week.

Hi All
I have attached a Mars image from 14 December. The dust appears to have
expanded southward. A possible secondary dust cloud in eastern Thaumasia.
See Paul Maxson's image taken 91 minutes later.

Hello everyone...

I have attached an image of Mars taken December 14th.  The image leaves a lot to be desired from an image quality
standpoint, but I believe that it is of interest with the current dust activity.

The image was taken with a 25cm newtonian that I am currently testing for planetary work, trying to avoid the focus
changes that occur with the IR and UV filters.  This image was taken at f44 using eyepiece projection with the
ToUcam Pro.  The RGB image was taken through a Schuler IRX filter, and the IR image was taken thorough a Schuler
IR83 filter.  Each frame is composited from approx 100 of the 800 frames in a 30second video clip.  Images were
stacked and processed with Registax2.

The images show a tiny SPC and a bright area covering much of the centre of the disk, roughly south of Chryse to
the Argyre area.  Is this some of the dust reported by others during the last week.  There are few other features
visible, though I think Sinus Meridiani is visible along the limb on the left side of the image. I would be interested in any
comments on the image that anyone would care to pass along (and corrections of any of the above if necessary).
