解説（安達）
ウートピア（Utopia；260W,+53)方面のフードは、今日も広がりを見せている。
フードは全体的に明るく見えるが、極付近は暗くなっている。Paulo Casquinha
とDavid Ardittiの北極フードは興味深い姿を記録している。南極付近は黄色っ
ぽい。やや濃いダストベールに覆われているようだ。(reported by 7 observers)
Hood of the direction of Utopia (260W,+53) shows a spread today also.
Although hood looks bright on the whole, the neighborhood is dark very
much. The North Polar hood of Paulo Casquinha and David Arditti is
recording the interesting figure. Near the South Pole is yellowish. It
seems that it is covered with a little deep dust veil.

Mars Images in fair seeing conditions.
A rift on NPH can be seen on B image.

[Paulo Casquinha Palmela,Portugal]
A good set of images was obtained on the morning of Oct. 11, through various
filters. These are presented as two LRGB sets in one document, and R(SG)B or
(IR)(SG)B sets in two more documents, one from an earlier period, and one from
later.
I was experimenting with the various R and IR filters I have, and these are all
labelled carefully, but in the end the results all proved actually very similar.
The further one goes into the IR, of course, the stiller the seeing gets, but
also, of course, the fainter the image gets, so one has to compensate by
increased gain or exposure, and these effects pretty much seem to cancel one
another out. If anything the Baader "IR" filter gives slightly less good results
than the others. This is not surprising as it is the only dyed glass filter; the
others are interference filters.
On Mars itself, the yellow bowl of Hellas on the limb remains bright, and the
fissure in the NPH is very clear.
