previously from the 19th but with a similar longitude on show. Again you can

My ideas of notes would suit better the post-apparition
notes, I think, from what you say - they're not generalist, even if I like to
call data from other periods for comparison purposes.
I'm going to propose a different thing for a more rapid
publication : recently I have been experimentating the LRGB method for imaging
Mars along with RGB, and I will write something on my experience. I think it
would be a good idea to have technical articles about Mars observations as
well.

So here is a list of future ISMO notes on the 2012 apparitions I'm thinking

-
Trend of the Tharsis clouds during the sol (from morning hazes to evening
orographics)
-
The cloudless northern hemisphere during 2012 apparition (2010 as well here)

A note to watch if we have detected the frostening of Argyre (when and how)

Dear Friends and Colleagues,
Yesterday and early this morning, Cassini completed, in
rapid
succession,
flybys of three Saturnian moons: a very
close encounter
with
Enceladus, and reasonably close flybys of one of the co-orbital
moons,
Janus, and its medium-sized moon, Dione. Though we've been in
orbit
around Saturn for nearly 8 years now, we still continue to image
these
moons for mapping purposes and, in the case of Enceladus, to learn
as
much as we can about its famous jets and the subterranean,
organic-rich,
salty, liquid water chamber from which we believe they erupt.
Check out our raw, unprocessed images from all three flybys

Some

Some excellent seeing occurred here on this
night (a full set of images will follow in the days ahead) but i wanted to send
these first as there is much of note, especially in the high quality B filter
image i was able to obtain.
Interesting to note the orographic clouds flanking the
volcanoes notably become weaker and fainter the further south in latitude you
look with Arsia Mons having only a very small and weak cloud flanking it. Also
interesting to note all the orographics flank the western sides of the
volcanoes with the Ascraeus cloud being far and away the brightest and largest.
Chasma Borealis is nicely seen in the NPC with fragmented outliers.

Except for a few floaters and retina blemishes my eyes are
operating great, or as deigned. The
right eye is still a little fuzzy but it seems to be clearing up as time flies
by. Last night while observing Mars I
put in a 10-mm EP in my focuser (with a 3× built in Barlow) and 1” extension
giving 940×. Seeing was okay with that, so I used an 8-mm for 1180× and the
extra globs on my retina got in the way creating some artifacts, often seen on
CCD/webcam images, so I backed off. So,
my maximum magnification will be 940×; however, 780× is just right for seeing
from 6 to 10. I only used the 8-mm so to
se mere detail in the NPC but the wind started interfering so I forgot that
idea.
After observing Mars using setting circles I pointed the
16” over at comet “Garradd” and by a stroke of luck it was in the field of a
26-mm EP that rendering it at 311×. Wow,
am I good or what? Anyway, after
putting in an old Lumicon Deep Sky filter in the 35-mm EP the comet came in
with a little more field. Using color
filters I determined where the dust and gas tails were. Neat comet looks like a fluffy ball cut by a
wide ‘V” tail(s). Bugs went to sleep so
a light breeze made observing grandeur oculus pro oculo.
Glad old Parker talked me into going back to observing in
real telescopes instead of virtual ones.

This
article from the ESA mentions the observation of auroral activity at
approximately
the same location of my observations of the Mars phenomena -
190E
and 43S.
"SPICAM
detected light emissions in the southern hemisphere on Mars, during
night-time
observations in the region corresponding to 177? East and 52?
South.
The total size of the emission region is about 30 km across, possibly
about
8 km high."
Further,
I have mentioned this possibility to a researcher at the Space

nights and I'm anxiously waiting for that one excellent night here before Mars
gets too much smaller.

Hi; here my Mars from this morning. Seeing was tricky,
very short moments with 6/10, but long times only 3-4/10. A lot of colour
sequences went wrong, but at least I could capture a whole sequence under
stable conditions at 4-5/10...

Dear Minami-san,
I
think there is a great deal of consistency between this theory and the
observations from the time period.
Attached
is a map I created showing the estimated location of the observed
cloud, based on my own and Don Parker's images.
Please note the location of the observation is only approximate, due to
the difficulties of measuring phenomena so close to the limb of the planet, due
to sharpening and other factors that can alter the limb during image
processing. However, we think this is
close and the measurement was provided by Damian Peach of 190.5 degrees by 43.5
degrees south. I note that the location
of the observation corresponds to one of the strongest areas of crustal
magnetism on Mars!
Further,
here is a link to the projected CME path of an M7-class flare emitted by giant
sunspot AR1429 on about March 13, possibly suggesting that the "peak"
observations noted by Don Parker and myself were the result of the recent, or
concurrent passage of a large CME and high solar wind activity that Mars would
have been experiencing.
http://iswa.gsfc.nasa.gov/downloads/20120313_185500_anim.tim-den.gif
If
we are lucky enough to have another CME that will affect Mars in the
near-future, perhaps we can provide an observation alert to amateurs and
professionals to obtain data and see if we notice a increase in visibility of
the phenomena at a time consistent with the passage of a CME or increase in
solar wind at the location.
I
am very interested to learn more of your theory as well as your analysis of the
information I have provided.
With best regards,

Hi Masatsugu, It's been a long time! I hope very much to

Fortunately, business has been very good. Staying up late at night is a real

I would have a very difficult time accepting lightning as
a cause, simply
because
of the prolonged time of "the event".
The atmosphere of Mars
simply
lacks the density for prolonged activity of this nature;
furthermore,
lightning near the polar areas would be far less sustainable
over
long durations than near the poles in sparse atmospheric conditions.
What
appears to be expansion of this "plume" also is evident in images over
a
two-three day period also indicative of scattering of a possible dust
debris
cloud; separation of the RGB components of some of the fine images
thus
obtained by other observers who have posted also reveal a reflectivity
consistent
with the Martian dust, and not that of atmospheric phenomena,
which
is currently quite active on the planet.

I suspect this is a rare trick of lighting, not a cloud. I
measured the position of the
feature
in WinJUPOS, and (if I did the measurements correctly) it appears to correspond
to
the highlands that surround the large Martian
craters
area
in question gets sunlight before the surrounding region at only this time of
year.
Additionally,
its appearance is exaggerated due to sharpening; the area of our planetary
images
most distorted by sharpening is the limb.
The
trick of lighting also explains its appearance in all wavelengths from near-IR
to
Blue.
I
could be wrong, so feel free to poke holes in my hypothesis.

This "cloud" on the morning
limb is truly extraordinary. Evening
limb
orographics are never this high. This feature reminds me of the
SL-9
impact plumes that were carried over the limb of Jupiter in July of
1994.
Moreover, it is prominent on the red as well as the blue
channel.
At the risk of sounding daft, perhaps it is of impact and
not
meteorological origin.
I agree with Roger Venable that one must
take the terminator into
account
when determining the height of this cloud. However Mars is
98.4%
illuminated now, so the terminator effect is minimal -- the
cloud
still has dramatic altitude. Furthermore I have never seen a
cloud
like this even when the Tharsis orographics are on the evening
terminator
during perihelic apparitions.
Who said that Mars is boring this year??

Dear
Masatsugu:
A
number of American amateurs have imaged a remarkable feature on Mars
during
the past two nights (including our esteemed Don Parker) in the
form
of a remarkable cloud projecting from the morning limb at a high
(60
degree?) southern latitude. Remarkably, it has grown in size over
the
last 24 hours.
As
Don Parker and I communicated by telephone less than an hour ago,
even
orographic clouds on the evening terminator are not this high.
Moreover,
the feature reflects appreciably in long wavelengths as well
as
short wavelengths and appears to have a dusty component that is
very
difficult to reconcile with the location and season.
When
I first saw the images thought of the famous 1892 observation by
Andrew
Ellicott Douglass of a prominent cloud projecting from and
deforming
the morning limb, as well as the Antoniadi observations of
the
peculiar greyish clouds that he attributed to volcanic ash. But
soon
the images of the 1994 SL-9 impact plumes rotating over the
morning
limb of Jupiter also came to mind. Given the altitude,
location,
and spectral character of these features, I suspect that they
may
not have a meteorological origin.
Images
by Wayne Jaeschke on the first night can be found at:
http://exosky.net/exosky/?p=1606
Parker's
preliminary image from last night is attached. I am struck by
the
extraordinary altitude of this feature, as well as its apparent
detachment
from the morning limb.

Hi, As planetary imagers and observers and Mars close to
opposition you might be interested in the write up of my investigations into
the 'edge rind' effect on Mars.
My conclusion seems to be it is an optical
diffraction effect - but see what you think. See

Received: Mon 19 Mar 2012 04:20 JST
Dear Masatsugu,
I
have two notes to propose to ISMO in a short delay :
1)
One about the trend of the Tharsis orographic clouds. Adding SAF and
CMO
images, I have a full set of detailed images showing how
the
other grow from local
that
the clouds show a strong westward trailing effect (that you must
have
seen on some images).
Interestingly
enough, this trailing effect looks to be a feature of
northern
spring to mid-summer only : to my surprise, looking at MGS
images,
I found that the effect disappear from around Ls 140° where the
orographic
clouds looks roundish (did you know it ?)
2)
The other about the very weak amount of white clouds in the higher
northern
latitudes. This one would be a basic note talking about the
water
vapor cycle and the general circulation on Mars (Hadley cell
during
northern spring/summer).
I
hope that this will be fine to you.

Dears,
Under acceptable seeing, Mars with my Dobson, showing many
clouds, on all volcanoes of Tharsis, Olympus Mons, Alba Patera, on the limbs
and slightly visible maybe part of the equatorial belt?
http://astrosurf.com/delcroix/images/planches/m20120312-MDe.jpg
I
like the elongated cloud over Olympus Mons, and the RGB has a kind of slight
"spheric" effect, maybe due given by the clouds on the limb and on
the volcanoes? These clouds are detailed in green, and really prominent in
blue.
Here is the RGB magnified by 125%

Dear Masatsugu, I have read Jeff's words
several times, and I even called him this morning and asked him about what he
meant. We had a very pleasant and friendly chat, as I had expected that we
would. Here is my understanding of what he wrote.
First he expressed his opinion that the
Rima Tenuis is not (or at least not always) an illusion or a result of some
amateur's mistake. He thinks that people have been seeing something real, which
is most likely dust stretching across the polar cap. Jeff agrees that the Rima
Tenuis does not exist as a topographical feature like a valley. ( I would have
guessed that, instead of a depression, the RT would have been a strip of higher
ground, where presumably the white would have sublimed earlier.) I agree heartily
with Jeff that people have been seeing something real. The interpretation of
the observation ( as a topographical feature) has been wrong. Jeff thinks
people are observing dust. I do too.
Jeff also wrote the following:
"Because some historical figures...little or nothing in the world of
science." I think he was saying that telescopic observation cannot answer
some questions. Perhaps he was also thinking of the low regard that some
professionals have for amateurs, especially Mars observers. Jeff did not mean
any disrespect for any observers, and he was not saying that we should not
observe. He was saying that there are realistic limits to what we can see. It
is also the case that, even if we see something significant, we might not be
able to explain it or to get the professional community to give us the credit
we deserve.
Back in the '80s I was one of the most
active Jupiter observers, and there was little professional interest in
Jupiter. When Shoemaker/Levy 9 rammed into Jupiter there was a lot of professional
interest, and very few people cared what I had observed. I just had to accept
that a big fish in small pond could be just bait when thrown in the ocean.
Jeff is a good guy who means us well. He
is a friend.
If I did not communicate clearly, please
let me know and give me a chance to try again.
I will try to write more later.
Sincerely,
P.S.
Perhaps you will like the following from my A Brief Flurry of Momentary Stays:

All,
Can we defer to a Martian? Oh yes, it's
just rumor that Dan (Mr. Mars) Troiani was born on that Angry Red Planet. In
fairness to his recovery of the RT (or is it a "recovery"?), let's
backtrack to
He has his 10" f/6, not quite two years old and the only scope he had ever owned,
sitting in front of his house and he sketches Mars at not quite 9" of arc
(and at 283x) and records the NPC with a "Y"-shaped feature running
down from longitude 333 degrees toward the pole (south up orientation). He next
dutifully sends the sketch to Chick Capen at
Chick informs Dan that he had detected
the RT, seen before in 1888, 1901, 1903 and 1918 and given its name by
Antoniadi (note the rhythm with aphelic apparitions, as it was in '79-'80) and
which had eluded him despite an over twenty year search sometimes with McDonald
Observatory equipment. Even the Viking II Orbiter, poised above the cap one
Martian year earlier, had not picked it up.
When I first met Chick (on the day, as it
turned out, Ronald Reagan beat Jimmy Carter) and informed him I had made Dan's
mirror, I got an extra special tour of the
The next four aphelic apparitions RT
would show up again and each time Dan had the first sketch of it. Dan is no
starnger to picking out the difficult. On October 24, '79 (another four o'clock
in the morning job) he caught what was described in a subsequent edition of the
ALPO Journal of the first disturbance in the Jovian STZ since 1944 and Voyager
II had passed the planet not that much earlier and had failed to notice it.
Speaking of Dan and spacecraft, his
drawing in mid-July, '94 of Jupiter revealed the "D" impactor of the
S/L-9 comet crash using just his 8" f/6,
possibly the only other sighting besides an image from HST.
I think Chick would tend to side with him
on this one, Jeff - but as always good to hear from you and that marvelous
wisdom you impart!
Yes, I still think Dan's a Martian,

Dear
all,
Less
than three months to the transit of Venus, and there are a lot of interesting
things going on already.
Venus Transit app
The
free phone app that has been announced for months has now finally been
released, both for the iPhone and for Android. On the day of the transit you
can use the app to measure the times of contact. By submitting these times to
our database, the distance to the sun can be computed, just like in the
eighteenth and nineteenth century. To practise, you can use the app's
simulator, showing the black drop at the interior contacts. Wonder what time
the transit will start from where you are? The app also computes the times of
contact for any location on earth.
The
app is a great way to get involved in the observation of the transit of Venus
on June 5 and 6. Instead of viewing on your own, you can now connect to
thousands of others watching the same spectacle. Instead of just looking at the
silhouette of Venus, you can now contribute valuable observations to the
astronomical community. Get the most out of the event, and become a part of
history at the same time!
Download the iPhone version from: http://itunes.apple.com/app/venustransit/id502494620?mt=8
Download
the Android version from: https://play.google.com/store/apps/details?id=awb.tov
Read
more about the app: http://transitofvenus.nl/wp/getting-involved/phone-app/
Partner search tool
The
transit of Venus can be used to measure the distance to the sun. Usually this
is done by pairing two observations of the transit made from two locations
distant from each other. If you are using the phone app, you don't have to
bother searching for partners: the app computes the solar distance
automatically using all submitted data. But especially for classrooms it's
interesting to work together with an actual observing partner hundreds of miles
away: students can team up in small observing groups and enter a competition in
finding the most accurate solar distance, or they can join the Astronomers
Without Borders programme with lots of preparatory activities? if one thinks
about it, a collaboration of this kind has endless possibilities, even for
individuals.
To search for a suitable partner, we have
developed a partner search tool, that will help you to get in touch with other
schools, groups or individuals. To populate the search tool, we would like to
ask you to register first at
http://transitofvenus.nl/wp/2012/03/06/register-for-partner-search-tool/.
Once there is a substantial number of registrants, the search tool will be
released at
http://transitofvenus.nl/wp/getting-involved/measure-the-suns-distance/.
New books
In
the next few weeks a couple of new books on the transit of Venus will be published:
Andrea
Wulf, Chasing Venus ? The Race to Measure the Heavens (May 2012, see:
http://www.andreawulf.com/)
Mark
Anderson, The Day the World Discovered the Sun (May 2012, see
http://www.amazon.com/Day-World-Discovered-Sun-Extraordinary/dp/0306820382)
Eros Parallax Project
The
Eros Parallax Project, run in late January and early February, was a great
success. Nearly 60 pictures were added to our online depository at http://www.flickr.com/photos/transitofvenus2012/
and even more people submitted their measurements of Eros' celestial
coordinates (see http://transitofvenus.nl/rest/eros/ for the results). Right
now, the data is being processed and analysed, an we hope to publish the final
results of the Eros Parallax Project very soon. It is exciting to see how, with
today's new technologies available to everyone, amateur astronomers can
actually measure the universe together? something that was unthinkable only a
decade ago.
I invite you to follow us on Twitter or
to join our group on Facebook to keep in touch with other transit enthusiasts.
This is also the place to look for announcements of events, talks and
exhibitions about the transit of Venus. If this email was forwarded to you, and

Simple
truth of the RT is that it was easily seen by many observers, but no one could
define what it was; even though HST and space craft images shows nothing there
except occasional dust streaks. IMHO,
and this came about 30 years ago, is that the Rima Tenuis does not exist and
that what we have seen is dust streaks crossing from ~330 to ~140 degrees
Areographic longitudes of the NPC. To me
it is the only plausible explanation given the MGS imaging, HST and or other
spaceship data. Because some historical
figures, and not so historical observers, see something on Mars in a telescope
means little or nothing in the world of science. I know that is hard to accept, but we have to
move away from conjecture and deductive mythology from ancient times; my
philosophy-101.
Sorry to bust any one’s bubble; but this hobby
of observing Mars must modernize and as my old friend, Chick Capen, use to
say when we discovered something of
substance, “this is real science.” Here
is one suggestion: using a good tool, WinJUPOS, to measure the NPC and all it’s
streaks or rifts one can easily see that the current images do not indicate RT
on any of them.

Hi
Damian,
Are you asking about images that show the
Rima Tenuis or the rift formed by Chasma Boreale?
The
image Christopher Go just took on March 6, 2012 appears to show the NPC Chasma
Boreale rift, east of the central meridian. Christopher’s image also appears to
show a smaller entrant into the cap in the vicinity of Abalos Undae, near 75-80
degrees W longitude, just to the left (west) of Chasma Boreale.
http://www.christone.net/astro/mars/index.html
Evidence in this next image is a bit weak
since it was taken at the wrong central meridian to get a clear view of the
Chasma Boreale area but the very faint rift crossing the cap seems to be in the
correct location. The MARCI image for Feb 22 shows some dust in Acidalium and
up to the cap but it also shows Chasma Boreale clearly.
http://www.damianpeach.com/mars1112/2012_02_22rgbseq.jpg
You should get a much better view with an
image taken closer to a CM of 60-90 degrees or so.
About a year ago I was looking at several
drawings that showed the Rima Tenuis. For the few drawings I checked there were
no spacecraft orbiting Mars at the time so I didn’t learn anything. There are
probably more drawings of RT than what I found but I didn’t put any more effort
into the search since dust flows across the cap are the only possible
explanation I am aware of.

Dear
Reiichi,
Thanks for your comments on the colors of
my RGB. This is not only because of my "DNA of visual observer" as
you say ;). As an analyst, I just believe that the interpretation of color
images is always facilitated if the processing keeps a "natural" or
"realistic" aspect. Otherwise the data is less reliable.
I did not even notice that bright reddish
patch next to Elysium! I have been
looking for data and found the solution on the Rosetta image in joint file to
this e-mail : it is a ground albedo feature, reddish in color, and the MOLA
data shows that the shape is like that because this is the western flank of the
Elysium slope...
So
your color analysis of images was just right: we do see it bright (and very
bright) in IR and R so the red color is implied (SBd image from feb. 23 is also very nice).
The existence of an opposition effect
looks also fine to me. This would explain how bright is Elysium currently in
near IR while the orographic cloud is not supposed to be visible in this band!
Re:
PS: I do not think however that we see the Bright Elysium in the sense that we
wrote in CMO 388: the summit is much too small for my spatial resolution, and
much too covered by clouds currently. But, the whole extended mountain looks
bright, yes definitely...

Dear Christophe, Your complete set of RGB, R,
G, B, IR, V and UV images is always very informative. And your RGBs are
impressive, most natural…they look exactly like what I see with my 30cm SCT…I
believe your sense of color balance to be an expression of your “DNA of Visual
Observer”.
On your RGB image on 04 Mar 2012 23:30GMT
ω=229°W ι=03° “the summit cloud of Elysium Mons” is clearly shown as
an well isolated bright whitish spot; it deserves to be called “white cloud” as
it is explicit even on IR as well as on R, G and B. I also noticed on the RGB
image, fairly strong reddish tint of the diagonal elongated bright patch just
off to the west of EM
summit cloud, which looks like a distant candle flame blowing westward. Similar
tints are also seen on other imagers' images as MLw's on 01 Mar 23:52 GMT, MDc's
on the same day 23:43 GMT, PEd's on
the same night 22:56 GMT, as well as on yours on 02 Mar 23:28 GMT and on 29 Feb
(EM summit cloud seems thinner on 29th, inconspicuous on IR), etc. MLw commented in his LtE on 06 Mar as
“Interesting colour variations in the Elysium cloud…”. But I think the
elongated diagonal reddish bright patch was not a cloud but an albedo feature,
because on your 04 Mar image set it is bright on R and IR, dimmer on G and
seems inconspicuous on B. Its location and shape suggest it to be the lighter
area adjoining inside the northwestern side of the classical pentagonal Elysium
which has been conspicuous in this Apparition (see attached MRO MARCI image,
the yellow arrow).
But what on Mars was the color? Was it a kind
of the opposition effect? Or just my illusion?
Good Seeing and Transparency!

Hi Gary, A very informative and

I'd be interested to hear further from
some of the veteran observers such as Masatsugu, Don, Richard etc who must have
seen or imaged this feature.
Are there actually any photos/images from
the last 20yrs which show the feature clearly? Don has been taking CCD images
which would reveal the feature since the early 90s and HST has imagery going
back to then. Is this rift just a visual feature or are there clear photos or
images of it from past apparitions? When was it last reported by more than one

Hi
Jim,
I thought that the MOLA topographic data
pretty much proved that there is no physical valley in the North Polar Cap in
the region of Rima Tenuis. MOLA vertical resolution is good to approximately 1
foot (30 cm) and shows no major entrant into the cap at a longitude of 320
degrees W. The polar dune field surrounds the residual NPC and is what creates
the classical dark ring known as the
By far the largest entrant into the
residual NPC is Chasma Boreale and dust has been seen within or near the
entrance of Chasma Boreale with some regularity in spacecraft imagery, I think.
At night katabatic winds will carry cold polar air downslope and out through
the entrance of the canyon and south of the cap. During the day some winds may
at times blow up the canyon. Chasma Boreale terminates about halfway across the
polar cap. A curious fact is that if you were to extend the arc of Chasma
Boreale past its terminus to the other side of the cap, the arc exits the cap
at a longitude of about 320 degrees W, the longitude of Rima Tenuis. I don’t
know if there is any connection between RT and the Chasma Boreale (I am not
saying there is) but it is at least a curious coincidence. I don’t know of any
other feature that would influence a preferential dust flow across the cap in
the region of the RT.
Don & Sean’s image on Feb 22 shows
the Chasma Boreale on the west side of Acidalium but the entrance of the rift
at the edge of the cap is obscured by dust. Their image along with a few other
peoples images seem to show a rift running almost all the way across the cap.
Chasma Boreale only goes about half way across the cap even as far out as Ls
150 degrees. It doesn’t get any longer, it just widens and becomes more
obvious. So, without invoking dust as a possible explanation to extend the
length beyond the physical rift, I got nothing for an explanation. The MARCI
image for Feb 22 shows dust from northern Acidalium, into Baltia and up onto
the cap but dust does not appear to be extending beyond the length of the
physical rift.
Just to be clear, the Chasma Boreale rift
is not in the vicinity of the
It would be interesting to hear other

Hi guys, The question about RT is whether
it corresponds to a real Chasm. I thought the consensus in the 2009-2010
apparition was that there was no chasm. If that is still the case, then RT
isn't a rift, but could either be a wall of airborne dust or a line of dark
sand dunes. My last blog for the Mars Alerts and observations page shows a dark
circular ring on the NPC. There is no sign of a linear feature in December.

Attached is an image from 1st March.
Seeing was good for my location, reduced transparency.

Image re-sized 1.25x
