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 Rowan University, who has
been doing a great job with transfering images from the ftp site
to the web pages. So far this is a task that is all done "by
hand" as neither of us has had the time to try to figure out a
nice script to take care of it. This time around we have a nice
full newsletter so without further ado...
                        -Dave

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 University
of Nebraska has provided a very good explanation of how such
brightenings could occur based on the reflective properties of
ice and the geometery of the Earth/Sun/Mars positioning. Some
follow-up ephemerides for future observations have been calculated
by Dobbins. Read all the details, and get your own copy of the
ephemerides at the Marswatch 2001 WWW site! The good news is
that the best chances for viewing them are still ahead; Gaskell
predicts that near the end of July will be best.

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 catlog, discussions, reference
maps and charts, and a portrait galleray (300 illustrations!). To
acquire your copy, send a check payable to "British Astronomical
Association" to the Assistant Secretary at their headquarters:
Burlington House, Piccadilly, London, W1V 9AG, Great Britain. The
cost is as follow:

BAA members resident in the UK or Europe: 10.50
Non-members, UK or Europe: 15.00
BAA members resident in North America: $22.00 (airmail)
Non-members, N. America: $32.00 (airmail)
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 Mauna Kea as
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.
