Dears,
Mars which turns out ok in infrared, with a bright albedo zone in
Elysium Planitia:

Same infrared colorized (keeping 50% of color luminance) :

Color version has a worse resolution but shows clearly boreal polar veil, and morning clouds on the terminator :

Hi all,

Missing out somewhat on all the fun in Valles Marineris, although I was able to catch a glimpse of it in IR742 in daylight and at low altitude as it rotated towards the limb. And I've been told often enough that if there is action, keep an eye on the rest of the planet as well for potential secondary outbreaks. Difficult to say whether the subtle markings over Tharsis are the normal albedo features, or dust. Comparison with the recent, wonderful, global maps from Pic du Midi and Andrea Vanoni should confirm.

Best regards, Clyde

Hi all,

Here is a set from the 9th, taken between many passages of clouds. Seeing went from fair to good but I had to pack under a slight rain.

These images are my first try to the processing method using a real PSF of a star, with the Astrosurface software. It does bring an improvement.

Hello,in the first part of November we had very poor conditions with instability and/or clouds .

Last night I captured Mars very high in the sky in unstable conditions but the altitude helped me produce a decent result. The SPC remnant still exist in the southern mid-summer. Lot of clouds are present visible in the blue channel.

Hi all,

With the latest fascinating dust developments in Valles Marineris (Great work by Ethan, Seb, Niall and Chris that I have seen so far), I had a crack at Mars in daylight conditions and at low altitude to try and catch the western extremities of VM.

Unsurprisingly, the IR is best, and might have caught the brightening right against the limb. Hoping to get some better views over the coming days, as long as it hangs around for me!

Best regards, Clyde

Please find attached my latest Mars image from last night.

I can see two bright patches linearly extending almost sideway, one across Aurorae Sinus and the other one over to Melas Lacus.

I wish the Mars were bit closer. I am looking forward to see images from other observes with a large telescope.

Received: 11 November 2020 at 02:44 JST

 

Hi,
I'm sending again my spectral data, because I made one error that has been corrected.

Since I'm using a double slit (one narrow, one large), the instrumental response when using one slit or the other changes ; the narrow slit being noticeably redder than the large one.

 

I have been applying a coefficient to the narrow slit spectrum of Mars so that it match the profile it would have had through the large one.

 

Another change that I made, is that I got aware that it is more simple, and more accurate, to retrieve the reflectance spectrum of Mars simply by dividing its accurately corrected color spectrum, by the theoretical spectrum of the Sun itself. This avoids the errors generated by the use of a star that does not exactly matches the Sun's own spectrum.

 

Please replace data :)

The morning hazes are quite conspicuous and a dust front is passing over Mare Acidalium - this is the second season of cross-equatorial dust storms, although this year looks quite.

Dear ALL,

Though being a bit late, I am showing here two sets of Mars images. For the 26 October session, the seeing was no good but not quite hopeless. But on 06 November, the red planet was a blurred fireball bouncing around the field of view, no SPC nor any dark features visually! I dared to observe Mars in a faint hope of capturing the sequel of the tiny dust observed at Juventae Fons on the previous day by overseas observers (Shigeru Kurisu et al. in Japan just managed to record the dust near the evening limb on 05 November though!) in vain.

 

Stay Safe,

Hi all,

My main focus on Saturday evening was Jupiter and the Juno PJ30 track, but I did manage to swing across for a quick look at Mars. The IR and R show some details in the Elysium region at lower centre.

Hi all,

To change a bit with Mars images, here are some spectra of the planet taken last week, with an Alpy 600. The spectrograph is used with ASI183MM Pro, guiding module, and a photometric slit 23/230µm.

 

Graph presented are:


1) The color spectrum of the planet. This depicts the direct spectrum that we are imaging ; this is a solar spectrum reflected by the planet's proprerties, and partially absorbed by our own atmosphere.

 



2) The reflectance spectrum of the planet. This describes the properties of the planet alone, without the Sun contribution.

 



3) A comparison with the Sun spectrum and identified features. The planet is showing basically two larges absorption bands, one in the blue/green, and another in the near IR.

 



4) Separated spectra of the some of the filters usually used to image the planet.

 



5) A synthetic colorized spectrum along with real images, for illustration.

How hard it is to image the planet in UV!

 


 

Best wishes,

Christophe

Greetings everyone,
Attached to this email please find my photograph of Mars taken on the 2nd. November 2020 from my home. The image was taken at
18:03 UT.

I took the images as usual with my 6 inch SOLIGOR MT-750 reflector. The images were shot afocal through a 15 mm Plössl eyepiece using a FUJIFILM JX600. I also used a 2x Barlow lens. Image stacking was done with REGISTAX. Further processing was done with IRIS and also ImageJ software. The eather conditions were only good for around 15 minutes. I managed to take this photograph during this time.

Sytris Major Planum is clearly visible along with Hellas Planitia just above it. The South Polar Cap can be seen also quite well. There is some cloud coverage just above Utopia Planitia in this image.

Best regards,

Hi all,

Many sessions backlogged, but i had to process this one first :-)

Finally some very good seeing at times for this session using the 1 metre telescope in Chile.

I especially love the aspect of the Tharsis volcanoes here poking through the morning mists at right.

Arsia Mons looks decidedly peculiar in appearance. Valles Marineris is well resolved along its length.

The SPC rift is also nicely resolved.

Hello I took many images tonight looking for the cloud streak shadow referred to as AMEC.

I was only positive of imaging the shadows of the volcanoes themselves. I did not notice any elongated streak.. I have added an anamated gif taken with baader IR filter showing the shadows of the volcanoes.

 

 

Could the streak be the shadow of the volcano passing over or though early morning mists.

Something like a crepuscular rays at sunrise? other than the actual shadow of a cloud?

Comments:
An image of cloud filled Mars (including cloud projections) from Oct 31. I used the Baader B filter this time for added cloud data.
Seeing was decent for this season, especially visually. 

This is around my 21st observation this apparition, hoping not last one as the season is only half over, but winter seeing conditions look bleak.
