Wayne Jaeschkeが今日もTerminator Projectionを記録した。この画像は注目される
情報を持っている。Projectionの付け根が黒いリングに囲まれていることである。3月15
日・17日に見つかった暗いリングを伴った斑点と重なる。Christopher Goはヘラス
Hellas;295W,-50)の東側の黄色くなった部分を記録しているが、ここしばらくの間に
拡がっているように見える。今回の姿は、新しい活動かどうかは判らない。

Wayne Jaeschke recorded Terminator Projection today. This image has information
to attract attention. It is that the root of Projection is surrounded by black rings.
I overlap with the spot with a dark ring found for .17 days on March 15. This
overlaps with the spot with a dark ring found for .17 days on March 15. Christopher
Go records the part which became yellow of the east side of Hellas, but seems to
open for these past several days. I do not know whether this figure carries out a
new activity. (repoted by 14 observers)

I am processing between my sequences an found a bright spot near solis lacus...
Is this a bright part of surface or the beginn of an dust storm?
This night I could use 1/91 sec. Exposertime with the DMK 31AF03.AS. for
red and green. The blue one I took with 1/60 sec.
This is the first time that I tried so short Exposer times. 2 more
sequences are waiting for porceeding...

Please forgive the verbosity,but I wanted to take a look at my data from
last night and didn't have time to re-write the description,so this copied
straight-off my website.
Here is a quick process of the last image from the session last night,
showing Mars with the terminator projection. That's the term that Richard
McKim,Director of the BAA Mars Section,used in his report today. So,I
think that's the most appropriate term to describe this phenomena until we
learn more about its nature.
The seeing was very good at times last night,but I chose to process the
last image of the session first because that's when I was most likely to
capture the CM (central meridian - the coordinate system we use to identify
what part of mars is facing us) where the projection is located. The
projection is indeed still present and looks quite like a "nipple" in this
image.
I will update this with additional images from the session (including one
that I think was taken in near-perfect seeing) this evening. Given that we
have one more night of possible imaging in the forecast,my plan is to take
data first and process later. So,I may not get to do a complete update on
this phenomena until the clouds and rain arrive.
Note the inset shows the terminator projection enlarged 200%,relative to
the original image,and slightly enhanced.
Our epic stretch of great conditions will be coming to an end soon,but we
had another night of excellent seeing last night to catch the terminator
projection and the appearance of the cloudy Tharsis region.
This first image was taken early in the session,but the seeing was
near-perfect at the time. Other than the very rare "flutter",the image on
the monitor was something I won't forget. It shows the a very cloudy
Tharsis region with Olympus Mons just past the meridian.
This image was taken a bit later in very good seeing,when the terminator
projection was just peeking over the terminator.

I think there is something strange north of sinus meridiani and pandorae
fretum and northern area.
I captured something away the limb of the planet corresponding to bright
patch in yellow light surrounded on the disk to a yellow cloud occulting
the features.
This is probably a dust cloud storm that I didn't collect last time the
21st.
However on 21st there was not the pattern accessible as this night. This
night with a similar CM the patch is difficult to see at the first look.
Nevertheless,some drawings here in different colors of this yellow cloud.
I will try to-morrow to see if the limb will provide this strange anomaly
again as shown this night.
For your perusal.
This needs a narrow follow-up.

Seeing was a little better this evening but condition was still unstable. I used a Baader UV/IR blocking filter for these images.
Sytris Major is prominent. The Hellas region has very bright clouds. There are also bright clouds at Chaos. The North polar cap is getting small.

It was taken with a Takahashi Mewlon 180mm and a barlow 3X. With a DMK camera and RGB filters. The seeing was not bad visually,but with more turbulence at the camera..

Attached are two drawings of Mars I made at the University of Leicester's observatory. I was kindly assisted by Dr. Hugh Sasse and we hoped to see if the terminator projection imaged recently was still present. In the end,Mars sank into the low cloud and murk before we could examine the longitude where the cloud was reported. Seeing was never more than average,and we had times when it was rather poor- I suspect this may have been dome related rather than atmospheric!
Drawing 1,0006UT (IL),Solis Lacus now well on view and looks rather foreshortened at this tilt as one would imagine. There may have been a brighter region with Lacus but I am not certain of this). Some dark regions present in Erythraeum,Chryse bright,and Acidalium is non the proc. limb. There appears to be a large bright cloud (or perhaps many smaller clouds which in these conditions look like one cloud) over the Tharsis region. A faint 'dot' was visible ijn the clouds- presumably the top of Olympus Mons? NPC seems to be a little less bright?
Drawing 2: 0020UT (W#80A): Light blue filter presents a nice view- for some reason Acidalium seems darker in this light. View very similar to drawing 1,only a little later. I had the impression of an brighter equatorial cloud joining the clouds in the Tharsis region,but it was rather illusive.
By 0155UT,Mars began to sink into the low cloud which was now rolling in. We stopped Mars observations at 0158UT (CM: 108.2)- no sighn of any terminator projections but in these conditions,I would not have expected to see any!
