Hello,

Mars from 20th March in moderate seeing showing a clearer view to that sent out previously from the 19th but with a similar longitude on show. Again you can see the location of the three Tharsis volcanoes and Olympus Mons seen as holes in the morning mists.

Hi all, Seeing was just fair for the 31th.

The bright Hellas is coming into view. I have made a small comparison

map with data from late february, the last period when we saw the region

from Europe. The season was Ls 76 and the basin was much less bright then.

Looking at images I find difficult to decide whether there is frost or no

Under correct conditions, I did my first trial LRGB on Mars with mitigated results as I could not get the correct color, and there are some differences (shape of Hellas ice, East of Acidia Planitia rendering, ...) which leads me to be careful about interpreting it.

The blue layer shows diffuse ECB, which is not really seen on the RGB.

Dear Masatsugu, ..

You once asked me to write something about the bright Olympus in 2005. I did never wrote anything because finally, I just found myself to deny the "frost hypothesis". This morning I found MGS data taken on 6th November 2005 that of course show no frost and so I thought that it was interesting to write just a short note. Please find attached a short note. I have also found images that completely confirm the old note I wrote on CMO #325 about the October dust storm from the same year. I will also write something here just to show how good the amateur data can be. Of course I still keep all the other ideas I have already evocated.

Subject: Retardation of the protrusion from the CME passing

Sent: 01 April 2012 at 08:09 JST

Dear Masami,

It seems the golden time of the protrusion must come two days or three days after the passing of the CME storm on Mars.

In Waynes case the CME came to the planet on 17 March at about 00:00 and was gone away already on 18 March at 12:00, and hence on 20 March around at 06:00 it is far from the planet. So you should take this retardation into account and should alter the Time Table for the possibility of the next protrusion: The protrusion must be something that should make compensation for a loss which occurred during the CME storm.

With best wishes

Dear Masami san, I was just speaking about the event occurred last 21st at the north mars area. I am sorry for the disturbance. I feel something was reported obviously on 22nd and aleatory last 23rd from me. This could bring something for the understanding of the phenomena revealed by the US observers for a side limb of Mars reported. Personally this was at the opposite limb of Mars the night after.

To be frank I attributed this to a storm activity (a yellow cloud because brighter under this color) and not to an aurorae activity. However, the 22nd night report remains obvious. Now I understand that this way of report undertaken visually becomes so obsolete, and more and more, that this cannot be considered. I think the notes mentioned on the sketch add something more than the sketch itself. Sorry for the disturbance. Feels that you will not bother of me now with my dozen of color filters.

we can derive the following as a Time Table of the expectation when we may catch the projection phenomenon. The CME itself is considered to reach the Mars orbit on around 4 Apr or 5 Apr. Note so that we should be on the watch for the magnetic area of Electris - Eridania Ausonia - Hellas region at dawn.

Dear Masatsugu,

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.

Best wishes,

PS: So here is a list of future ISMO notes on the 2012 apparitions I'm thinking about, but I don't know what kind of topics you have already considered -

- 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)

- Brightening of some Martian relief because of the opposition effect (Tharsis/Elysium)

- of course a note on the frostening of Hellas, this one should have a strong comparative dimension (with 2010, 1997, 1999)

Received: Thu 29 Mar 2012 10:11 JST

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 here:

http://www.ciclops.org/view_event/169/Enceladus_Janus_and_Dione_Rev_163_Raw_Preview?js=1

And for my take on just why Enceladus is /the/ place, in all the solar

system, most deserving of immediate flagship-scale investigation, with a

spacecraft properly equipped to address questions about possible life,

here's an interview I gave, published today on the NASA website, for

NASA Science News:

Some preliminary images from March 14th (currently wading through a huge backlog of imagery.)

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.

Mr. Minami,

I wanted to bring this to your attention:

http://www.esa.int/esaCP/SEMLQ71DU8E_index_0.html

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

Science Institute and am hopeful that we can obtain resources from NASA

(preferably the Hubble, but that will depend on the availability of other

resources) to image Mars at a time when a large CME is going to impact the

planet.

I hope you find it helpful.

I hope we get some more clear skies here. I'm still struggling with the seeing on most nights and I'm anxiously waiting for that one excellent night here before Mars gets too much smaller.

Best wishes,

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...

Greetings,

Ive had a few attempts to observe Mars recently where I had to abort the session because the seeing wasnt good enough for me to clearly see sufficient detail on that little disk. I returned home from a two night star party our astronomy club held in Venus, Florida this weekend. Friday night was a great night for deep sky observing. I sketched Comet Garradd and M95 with its supernova and enjoyed great low power views of galaxies, nebulae and star clusters, including the fabulous Omega Centauri globular. The seeing, however, was so poor that the only feature I could sometimes clearly see on Mars was the north polar cap. The sky wasnt so transparent on Saturday night, but the seeing was better, despite the windy conditions. The sky was hazy, with lots of clouds off to the east, west and north, but I was able to observe Mars in a large sucker hole around the zenith. I was able to see coarse detail only during moments when the wind died down and I alternated views at 224x and 311x. I was unable to use my 400x eyepiece and that kept the image scale smaller than I would have liked. To improve the image for scanning into my computer, I made the drawing darker with more contrast than it actually looked in the eyepiece. I think I overdid it in this case and will back off a bit the next time. The separate tonal drawing has been uploaded to the New Images file. This is the most difficult Mars apparition I have experienced.

Regards,

Jay ALBERT (Lake Worth, FL)

I guess capturing Wayne's Icy Cloud is not for here, no special features, just clouds and haze. The bright cloud (spot) looks like a reflection of the Sun on a Martian Cloud. On the RGB image you can see a layer of thin haze covering the East side. Also include a Red and IR742 images to compare.

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,

Wayne JAESCHKE (West Chester, PA)

Hi Masatsugu, It's been a long time! I hope very much to get out and acquire some images of Mars this apparition. I recently moved and had to leave my observatory behind until I find a place to set it up again. Fortunately, business has been very good. Staying up late at night is a real challenge after long hours at work! But with all the exciting Mars images I've seen this year, it will be hard to sleep no matter how exhausted I am.

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 Newton and Copernicus. Thus the

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.

Dears,

FYI, as mentioned by Christophe Pellier, the zone were the cloud

detected by Wayne on March 20th was well observed by several French

observers (and I am sure by other European observers) a few days before,

showing in simultaneous observations what Christophe pointed to us

already at that time as a suspected high altitude cloud.

Here is the observation I made on March 12th (8 days before Wayne's),

where I measured the feature around 194 longitude / 45 latitude (in

Terra Cimmeria?) :

I also measured Wayne's excellent image 8 days later, where the feature

is bigger, at ~193 longitude / 42 latitude :

On Don Parker's image the day after, the feature looks way bigger and

elongated, over the same zone:

It might be the real thing. I imaged two side by side brilliant white clouds

on seeing the images, that it looked like clouds that would be

produced from an icy comet impact. I'll put something together for JALPO.

Hi All,

When I first started processing these images, I was ready to smash

my telescope because of the terminator "defect!". But thanks to

Wayne's great work my scope was spared.

http://www.kwasan.kyoto-u.ac.jp/~cmo/cmons/2011/120321/DPk21Mar12.jpg

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?? :-)

Subject: Impact plume on Mars?

Received: Thu 22 Mar 2012 07:33 JST

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.

 

More news to follow soon.

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

Comments most welcome.

Subject: Proposals of notes for ISMO

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 Olympus and

the other grow from local noon to the evening. The particularity being

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.

Best wishes

Here are some images from March 8th. I observed visually for a time at 400x and was struck by how brilliant the Olympus orographic cloud was - easily the brightest thing on the disk, far brighter than the NPC. This aspect really shows up nicely in the image with the dark summit punctuating the cloud.

The amount and the variety of clouds found on the Tharsis hemisphere is just amazing! This set is taking at the time when the orographic cloud over Olympus is just beginning to form. They are already formed over Arsia/Pavonis/Ascraeus.

I didnt record some fleeting, uncertain glimpses of spots on the disk in blue light because I was much too unsure of what I saw in the poor seeing as the clouds rolled in.

Dear Mr. Minami

I attach Mars image set on 13 March 2012. Seeing was little good while my physical condition is good.

Hi Guys Here in the UK we had early excellent seeing for 41 deg alt. I had just long enough to capture one LRGB set before clouds ruined what could have been a legendary evening. Olympus and Tharsis calderas are shown as is Valles Marineris coming onto the disc .

Masatsugu MINAMI-sama: The sky was more stable than yesterday, but at the Mars time cloud floated so that the images look not satisfactory.

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%

Bons cieux!

Hi Chirstophe & all, Actually in my own images for which i was lucky to get a bit better quality than Jean-Jacques on last night (see attached), I would actually say that the cap right on North pole is very white, but the streak southern is more yellowish, don't you think?

Very nice Jean-Jacques.

On your two last sets of images, mine of the 11th and Silvia K. on the 9th, the north polar region looks really yellowish

The transparency was poor and the wind was sometimes annoying.

Important humidity. T = +7C

Hi all, Is this brightness of the clouds an opposition effect? Clouds much

brighter than the ice at northpole?

http://www.kwasan.kyoto-u.ac.jp/~cmo/cmons/2011/120309/SKw09Mar12.png

My conditions have been extreme suboptimal. I had to capture the images

through a thin cloudlayer. :-((...
