Hi everyone,
Last night the seeing looked very promising early on in the
session but unfortunately it did not last long enough to catch Mars at a higher
altitude.
Even so I think this is my best Mars image set to date.

Hi,
Thanks to Clyde
Foster and Efrain Rivera Morales for their excellent images of the Hellas
region. They provide evidence of strong straight-line winds producing waves of
dust off of the crater's floor. I think this may be the first time that ALPO
has recorded such events. This is exciting to me! The clincher is Clyde
Foster's May 9th image showing what was a wave of dust
hitting the 6-mile high crater wall. Before these pictures, we would
have said that this was a dust storm.
Please see The
Association of Lunar & Planetary Observers ALPO Home Then go to the Mars

Good seeing,

Hi all,
Two captures of Mars
from yesterday evening. Seeing conditions were still poor, but certainly
improved from the previous few evenings. I am not sure if I have noted the
hook like feature at the NPC before, extending south and then to the east. The
bright spot, particularly in red, immediately on the north side of Valles
Marineris also caught my attention. It was an evening spent between the
observatory and the TV, with the Champions League final on. Thank goodness for
PVR- I didn’t miss any of the action, albeit a bit delayed!

Interesting
article on the Mars Plume occurrence from 2012. Interestingly, their paper
concurs with the initial theory of Masatsugu Minami. Many of the astronomers I
discussed the theory with, at the time, discredited the idea (even though we
knew that there was a strong, fast CME hitting Mars at the time and the plume
was over the area of the planet with its highest crustal magnetism).

BAA MARS SECTION DUST
STORM ALERT
2016 May 26
Dear Observers:
Images taken by Efrain Morales Rivera (Puerto Rico) in the last few days (May
21-24) clearly show a changeable bright yellow streak of dust at the IAU
western (following) edge of Eysium. The bright cloud was very conspicuous in
red light and was not related to the usual orographic cloud activity over
Elysium Mons. The Director had observed the area on May 16 without seeing the
storm, while on May 23 the Elysium region was too near the morning terminator
for the correct longitude to have been visible to him.
Evidence for previous
telescopic dust storms in this area exists, but such events are very uncommon
for Elysium, and sometimes the area has simply been a secondary focus of
activity for another dust storm developing elsewhere, such as at the start of
the 2001 planet-encircling storm.
If you are able to do
so, please monitor the area and send me your reports. Secondary activity could
occur elsewhere at any time now, though an image by Clyde Foster centred at
longitude 101 degrees on May 24 shows that hemisphere to be free of dust.

Hi

I
stacked the images in AutoStackkert using drizzle. Then to Regi-Stack 6
with the
Wavelets
set at default Initial layer 2, wavelet linear.
The
sliders 1,2 and 3 set to 10, sliders 4,5 and 6 at 1. The images
were imported into

and a RGB combined.
Then,
I used Astra Image Richardson-Lucy
to
deconvolution with a mild Gaussian blur. Then, I resized and used dust
and scratches set
at
two. Imported into Pixinsight to smooth with TGV Denoise set at three. The
image was Despeckled

reduced in sized, contrast and brightness adjusted. Then noise
was reduced by using Topaz Denoise
set
at 6.
I
cannot reproduce the ? by reprocessing the image from my raw data. I
am suspicious that
the

this time because
the

Edit- I see that I was looking at Peter's May image comparing it
to Mike's April image.
Sorry for the mistake, but comparing the features themselves still
supports my skepticism.
I'm afraid I see this as processing artifact. Compared to Peter
Gorczynski's images of the same region
http://www.kwasan.kyoto-u.ac.jp/~cmo/cmons/2016/f_image.html
which was taken either just after Mikes image, or 24 hours later
(Mikes time seems to be wrong, based on the planets features). From what I can
gather of Mike Hood's image, the processing blends areas all over the globe in
such a way that it is creating odd linear features where there wasn't any
before.
Maybe he has something, but I am very skeptical.
I would like to see the raw stack (pre-sharpening) before jumping
to conclusions.

Hi

Your
April 19th images show what I think is an impact of a small asteroid or small
comet nucleus marked by the bright spot in the images. Then there is an ejecta
of material in the form of a backward looking question mark. The only other
explanation that I can think of would be an eruption of some sort. I think it
probably is an impact. I annotated your image with the previous dialog. See the

Do
you have any AVIs recorded before or after the image you processed? If so,

the computer screen when the avi's were recorded, and visually only the
northern albedo features were seen.
Good color balance
was difficult to achieve on the final image which is slightly too yellowish.
Olympus Mons near the

Dear Masatsugu,
In the
near future I will be working on a new Mars book (actually an update of
"The planet Mars"), with Jim Bell providing an authoritative account
of developments since I wrote the first edition (it was published before
Pathfinder arrived in 1996). No one is in a better position to do this
than Jim.
I sent
him tidings of the Edom flashes--or glint--and here's what he says:
"Thanks for sending the Edom glint information. It seems like
an interesting phenomenon, but is likely not related to surface composition or mineralogy
(there's really nothing unusual there, based on spacecraft measurements).
Rather, I bet it's physical properties, like slope or
exposure of some particularly slabby bedrock or something. It is
something that could be looked into using modern spacecraft data sets. We've
seen a pretty intense sub-solar (zero phase angle) glint in daily MOC and MARCI
global mapping images for decades, so it's not particularly unusual or
surprising to see the surface glint at low phase angle. Maybe that's just
the most extreme example. We should ping Bruce Cantor at MSSS and ask him
if he sees that glint in MOC or MARCI images when MGS or MRO flew over
Schiaparelli crater at the right geometry. Or maybe he or Phil James have already looked into this...?
-Jim"
I've
been having a great time roaming through the archives at Lowell, and have found
a lot of new material; I attach, for instance, a page of notes from the
Japanese phase, in which someone who was obviously very fluent in Japanese
(Yejiro?) wrote out a haiku and instructed Lowell as to its meaning. I
have similar notes in my diaries where you did the same for me.
Hope you
are able to observe Mars.

I
arrived in Flagstaff about a month ago--my wife Debb and I (and two dogs) left Minnesota,
traveled across the agricultural wastelands of Iowa, Nebraska, and Kansas
(including Larned, where Clyde Tombaugh took the >train, with only a one-way
ticket, to Flagstaff in 1929), Oklahoma, then the more interesting states of
New Mexico and Arizona. My wife had to return to Minnesota to tie some
things up, but I remain here.
I spent
a productive day in the Lowell archives--I have been working on Percival
Lowell's last year for an article or two; and found some very interesting

have not been uncovered before. I am sending, as an example of what I
found, two drawings of Mars from March 14, 1916. He was seeing very fine

diabolical seeing conditions when there have been gaps in the cloud. I spent a

reasonable. Am busy working on the processing. In the meantime, I have done a
comparison of the new Hubble image with the closest I could get, with one of my
better images of the apparition, albeit 10 days prior to the Hubble image, so
cloud detail is not comparable.

Dear Richard and Masami,
Sending you here a Mars image from May 5, the best one I have yet
acquired this season.
It is nothing to write home about and should of course not be
compared to what others are getting this year, as the elevation and observing
conditions are exceptionally difficult. But at least there's some very
recognizable surface details, a bright Hellas and a southerly SPH (?) skirting
the slightly off-pole position is visible.
Mars was only at 12 degrees altitude and the seeing was a
horrible, fast undulating 2/10. An ADC combined with individual processing of
each color channel brought out what was there.
Hoping to get another couples of chance with Mars before this
apparition is past, bright summer skies are approaching fast.

Dear Damian
Some very nice work here. Of course, these are similar source materials to the
images that Johan Warell and I had digitally composited in colour for the first
time (and indeed derotated) for our paper three years ago in the BAA Journal
(volume 123 part 3 pages 137-142 (2013)). We used images from 1941 to 1956.
There is certainly scope for further work in this field as you have shown here.
In our case we were sent copies of the scanned film originals. There must be
many more sources of this sort of material, particularly if one were to be
content with R(G)B type composites. The late Dr Dollfus used the method to get
some less grainy Jupiter photos from the 1890s. Slipher's tricolour work goes
back many decades, yet he rarely made colour composites himself, owing no doubt
to the large amount of labour needed at that time: if I recall correctly he
only published composites in colour of his Mars images from the 1954
opposition. Slipher's best Mars images are from 1939 and 1954, both occasions
where he travelled south.
