A definite expansion of dust clouds inside and near
The dust
cloud has no more particularly bright area, and looks diffused, but it is definitely
a dust phenomenon, as judged from the ccd images produced by KUMAMORI and
MORITA on 26 June, covering a large region from
KUMAMORI
first sent to me a processed image (made from Sony Video images) taken on 26
June at LCM=277 degrees W (at 14:29 GMT), and meanwhile I received a set of
good ST-5C images from MORITA also on 26 June at LCM=275 degrees W and 285
degrees W.One hour ago I had a conversation on the phone with ISHADOH at
Okinawa (he was at the eyepiece with a wireless phone), and I am convinced that
the phenomenon is surely developing on the area.
M Tyrrhenum
has been slightly faded these days and looked weaker than Syrtis Mj and M
Cimmerium, and showed a much fainter area inside it near the mouth of Hesperia
on 24 June (184 degrees Ls), as observed from Fukui. Most part of M Tyrrhenum
is however apparent even today according to ISHADOH.
We are suffering from the rainy season in the

The area is
at present facing to the Oriental countries, while its effect may be caught
soon in
Further news
as well as the images will be posted in our CMO Web-Site.
Thank you for
your interest, and I look forward to further information,

Subject: Dust Cloud Further Develops

This is a second report:
The dust
cloud now shows its vivid aspect, swirling from
It is quite
big and definite and looks stable.
I have just
received two processed image-files from AKUTSU and KUMAMORI made this night on
27 June.
AKUTSU's set
of good images were compiled at LCM=258 degrees W
this night on 27 June at
KUMAMORI
succeeded to shoot the dust cloud slightly earlier at LCM= 248 degrees W by the
use of a 60 cm Cassegrain at Sakai, Osaka equipped with a Sony TRV-900 Video
Camera. The still image is a composite of 380 frames (this is nowadays
possible!) and since he used an artificial colour to feature the cloud, the
area covered by the dust is clearly identified.
The spc is
still clearly seen (in a smaller size, but well whitish bright) and the nph
also develops.
I hear HIGA
was also aware of the phenomenon independently.
We are going to update the CMO Gallery with these
images if the day breaks and our working colleague is not so busy.

PS or a third short report:
Yukio MORITA
has just completed his images at LCM=264 degrees W. It shows more
Just a
comment: Mare Cimmerium is completely out of the cloud, not affected by the
cloud yet. The cloud is located to the west of the line of 250 degrees W. Even
the tip of the NW end of M Cimmerium is clearly visible.
I am sorry I
must go to bed, and so details with a filing of the images will be done this
evening JST.

I look forward to seeing the images and hope we can
get others out to keep track of this storm.

Dear Marsphiles,
Welcome to the month of Mars! These next few days are part and parcel of
what it's all about for Mars observing.
Opposition
provides us with the biggest and brightest Mars
we're going to get for then next 25 or so months. I am just waiting for the flood of
images! I have to express great thanks
to Kaniz Zaman, a computer sciences student here at

Some of the observers who have been sending in
images reported a possible brightening in the Chryse region. Such brightening can be due to dust storms
(if brightening is most significant in
red light) or clouds, fogs, or ground ice (if brightening is most significant
in blue light). In an effort not to
entirely duplicate efforts of others, I will point everyone to the text by
Jeffrey Beish of the A.L.P.O Mars section at:
http://groups.yahoo.com/group/Mars-ALPO/files/Martian%20Chronicles/MC2001-15.htm
(I hope that comes out on one line for you, if not,
you'll have to cut and past it into your browser address line. I'll be
providing a link to it from the Marswatch 2001 WWW page.
There
was another report of Chryse being more yellow than normal on April 28th and
brighter than normal in red (Wr. #25) on the
29th. Check
out the images at the Marswatch 2001 images pages!
If
anyone can digitally ratio images of Chryse from different times, but the same
viewing conditions, it would be interesting to see the results.

Earlier
in the month Don Parker reported seeing bright "flashes" in Edom
Promontorium. These flashes occur in 10
to 15 second intervals with a duration of around 3 seconds. Don made the
search for these flashes based on an article in the May issue of Sky
& Telescope by Thomas Dobbins and William Sheehan. The best explanation so far is that the
flashes are due to reflections off ice clouds above the region. Martin Gaskell of the

Richard
McKim, long time Mars observer and director of the Mars Section of the British
Astronomical Association, has compiled a rather extensive Dust Storms
Memoir. This 168-page book is a complete
narrative account of all telescopic dust storms observed since records
began. It contains a catalog,
discussions, reference maps and charts, and a portrait gallery (300
illustrations!). To acquire your copy,
send a check payable to "British Astronomical Association" to the
Assistant Secretary at their headquarters:
BAA members resident in the UK or Europe: 」10.50
Non-members, UK or Europe: 」15.00
BAA members resident in
Non-members,
Those living elsewhere please contact the Office for
details of costs."
Note that the office does accept US dollar
checks! Rumor has it that they have
recently set up the ability to take credit cards, but you'll have to contact
their offices for more information.

I
received an interesting suggestion on the presentation of the Mars images we've
been collecting. I must admit that the
method in current use is more one of "tradition" and convenience
(both in programming the pages and in organization chronologically). The
suggestion was that perhaps we could present the images by contributor/observer. It is an interesting idea as we end up
getting a sort of "rouge's gallery", if you will, of the various
observers, their methods, and their "artwork" all in one place. Note
that I will not be able to get around to this until after the bulk of the
observing is finished -- it would require far too many updates to far too many
pages each day. If anyone has any
comments or suggestions on this idea, let me know as I consider it.

Since
opposition is upon us, I include here some epherides for observing Mars. The data were calculated using
the observing station (although that will not affect
the out put generated here). The program
used was the wonderful web-based
Ephemeris Generator located at JPL's Solar System
Dynamics site. If you want more detailed results, point your browser to
http://ssd.jpl.nasa.gov/horizons.html
and they'll get you going.
Note
that this is also linked from the Marswatch 2001 site.
Following is the table of ephemerides; you may want
to turn off your e-mail program's "word wrap" function to see it
properly.
