Hi all,
Testing
a new telescope last night i imaged the colourful double star Alpha Herculis
with an excellent result obtained. The colours of the components appear here
just as i saw them visually. I had not realised both stars themselves have
companions - though i may need a slight increase in aperture to catch those ;-)
The

Hi all,
Seeing
was just about good enough to put out a full data set, although the B was very
poor.
The main
albedo features around Valles Marineris (almost centre) and Solis Lacus (just
above centre) can be seen which indicates to me that there is not intense,
large scale dust activity in this region.
However,
I again have the perception of yellow-brown clouds or haze over a lot of the
terminator region as well as possibly extending across the southern regions
near the SPC.
Itfs
just a pity that the recent seeing conditions (for a lot of southern observers
it seems) have been poor. The session yesterday morning was a total write-off.

Dear
Makoto
I wish
to agree with Roger Venable. Your first message was clear, and like you, I
always have to ask imagers to adopt a consistent processing style. During the
2018 global storm (as in 2007 and 2001) too many observers increased the
contrast greatly. Some also thought the S. Polar cap must always be white, and
changed the colour balance, but reduced the scientific value of their work.
I found
the visual observations to be still important in determining exactly when the
2018 storm ended.
As
Roger says, there is the chance to make a more highly processed image, but the
original one should always be shown.
My best
wishes to you,

Sent from my iPad
On
Mr. Adachi --
Thank you for this message.
I found your previous message about the
color of the SPC to be clear, and a good message. Please do not be concerned about
it. It is true that, when there is dust obscuring albedo features, imagers tend
to process images by increasing the contrast so as to make Mars look
"normal". In doing so, they make their images look quite different
from visual observations. It is best for imagers to process their images
approximately the same, even when there is dust, so that we can tell more about
the dust in the atmosphere. After such normal processing, it is okay to also
process the same image with increased contrast to bring greater emphasis to
albedo features -- In such a case, two different processings of the same image
are appropriate. The key here is to always make a normal processing of every
image, for that is the most useful processing. So, I agree fully with
you.
I read your comments about images
often. Please continue the good work that you do.
-- Roger Venable

Hello Clyde Foster and Jim Melka, Hello
everyone.
Ifm
Makoto Adachi, Responsible Mars Data Archiving, ALPO-Japan.
On June 27th, I sent the following
email message.
iQuote from herej
Mars around this time is globally dusty. A dust storm occurred on June 22 near
Aurorae Sinus.
Look
at the image on June 22nd. The Marineris Gorge looks like a bright yellowish
band as it did in 2018.
This
shows the dust spread over the valley.
@The sunny part is recorded black like
the south side of the dust storm.
In
the contrast of the red image is strongly processed. In this
image,
the northern edge of Mare Cimmerium is dark. When it's faint
with dust,
it's natural to treat the contrast sparingly.
If you are shooting, please
be careful.
iUp to herej
I thought if the red color of Mr.
Clyde Foster's image would be well-balanced, it would be better to compare with
the visual observations, so I sent the email. But I seem to have said something
extra. sorry.
I confused you because I didn't put my signature when I sent it. I'm not
good at English so I always have a hard time. Therefore it seems to have made
many people feel uncomfortable, including Mr. Clyde Foster that I regret it.
I review and write daily
comments in the Mars report of ALPO Japan. I am sure that it is not written in
good English, but I would be happy if it could be useful for everyone who is
watching Mars. I review all your observations when making this comment.
I want the image for making a comment to be a well-balanced image so
that the colors and patterns are not too dark. Apart from that, we also need
something special for clouds and patterns only.
When the image is emphasized processed hard, Martian atmospheric information
is buried. Even if you send it with much effort, it may not be usable for
comments.
We look forward to your continued
observational reports.
I pray that the weather will be fine.

My
apologies in advance for the over processing of the RGB and somewhere along the
line I lost the plot with the colour balance. If I have the opportunity to
redo, I will.
That
aside, there is some crazy stuff happening out on Mars, which I felt warranted
sharing quickly. I believe I was able to capture the western regions of the
recent dust activity and note the following:
a) Olympus
Mons is the dark, reddish spot at lower right.
b) The
"anomaly" SW of Olympus Mons, that I have been noting recently, is
very evident.
c)
There is an amazing cluster of what looks like dust cloud "pillows"
extending across the broad region immediately south of (above) Olympus Mons.
d) Itfs not conclusive, but to my eye, it looks to me that
there is dust extending across the southern albedo regions.
e)
There may be a patch of dust extending onto the SPC

Another attempt at trying to detect the western extremities
of the dust storm in and around Valles Marineris, which is not quite in view
for me yet.
Nothing
obvious that I can note, although there is the perception that M Sirenum is low
contrast and hazy, I should get a better indication as Solis L and VM come into
view. Olympus Mons is at lower centre and Arsia Mons and Pavonis Mons can just
be detected. The feature that I have noted previously(most
noticeable in IR), SW of OM, is at approx 147 long and 5 deg N. This
corresponds to the Eumenides region (Lucus Planum on my National Geographic
