Hi all,

We had some good seeing on the morning of the 27th. A detailed view of the planet despite the small apparent diameter.

Quite remarkable just how much the region centred on Margaritifer Sinus has changed as a result of the 2018 global storm.

Hi,

Clyde Foster has sent me images of Mars on Feb. 21, 26 and 27.

After seeing the 27th image I finally realized that all three likely show regional dust clouds in and around Hellas. It was the "finger"of dust on the Northern edge of the SPC in the 2020-02-27 image that got me looking more closely at the three images.

I posted a composite of the three images in an album I created titled "Dust storm alerts" on the Mars Observers web site. I've attached the composite image below. These clouds may be an indication that the SPC that is now visible has started to sublimate. Sublimation has been known to generate high-velocity Winds. Congrats to Clyde Foster for the detailed images.

 


Good seeing,

Jim MELKA (Chesterfield, MO)

Hi all,

Whilst most of this morning's session, where I had some nice seeing conditions, was spent on trying to cover the GRS region of Jupiter comprehensively, I did swing across to catch a quick set of Mars data.

There is quite a concentrated cloud over Elysium at lower left. Syrtis Major is at centre right and there is some detail visible across the planet. As with yesterday, Hellas does not stand out. There appears to be some structure in the southern polar clouds.

Hi all,

It was nice to be met by clear skies this morning after a lengthy period of cloudy weather. Some reasonable seeing conditions came with it.

A well-defined Syrtis Major is at centre right, and it is interesting that Hellas appears to be almost clear of cloud and frost and is not clearly defined. There is substantial cloud over Elysium, which is on the evening terminator at lower left. I also think I may have captured the small North Polar Cap at bottom.

Unfortunately there is a severe edge artefact over the bright sunlit limb (can be processed out, but felt that I should present the results "as-is").

Hi all,

Mars has been passing by the two famous nebulae in Sagittarius during recent days.

Here is the view captured this morning. Wonderful to see the planet against such a rich backdrop!

Hi all,

I just managed a single capture of each channel before clouds closed over this morning.

It appears that Hellas is already losing its winter coat. There appears to be a few scattered clouds, but most notable is a bright cloud on the southern edge of S Meridiani at upper right. Syrtis Major centre left.

Hi Clyde,

Thanks for the De and Ds. It's late summer in No. Hemisphere and most of the NPC has sublimed and I suspect we're seeing is desert where there used to be ice. The positive Ds means there is plenty of sunlight to illuminate the NPR.

Good seeing,

Image set from this morning with S Meridiani central. I note that the north polar region is quite bright and appears to have a reddish tinge. Possibly an indication of some dust?

Hi all,

I was up a bit late this morning (hey, its Valentinefs day....) and only managed one data set before rapidly moving on to Jupiter.

Reasonably happy with the result despite some edge artefact on the bright limb. Very similar view to yesterday, with frosty Argyre I at top centre and some equatorial cloud.

Hi all,

Returning from a 6 day breakaway, I was met with a rather busy Mars this morning (I see it is just over 5" now). Niliacus Lacus and M Acidalium(below) are at lower centre. Mare Erythraeum extends across the upper region of the planet with a frosty Argyre I at upper centre. Nilokeras is to the right of Niliakus Lacus, with Lunae Lacus to its upper right. Aurorae Sinus can be seen. The Indus extension appears to be prominent. S Meridiani is at centre left. Some scattered clouds can be made out.

Hi all, here's an image of Mars from this morning in reasonable seeing.

Sinus Meridiani is the prominent horizontal feature just below centre, with the large crater Schiparelli showing as a small brighter notch on its northern extent.

To the upper right we see Syrtis Major setting close to the limb, partially covered by a region of late afternoon cloud.

Hi all,

Persistent cloud remains over Olympus Mons (lower right of centre) and the central Tharsis Montes. There is significant late afternoon equatorial cloud over the Xanthe region as well as cloud over Tempe (lower left). I believe Vallis Marineris can just be made out to the upper right of the Xanthe cloud. Solis Lacus is coming into view at upper left.

 

In the B image an interesting string of clouds can be seen extending from the centre to the North Polar region at the bottom.

Hi all,

A rush to beat incoming cloud, and I only managed one capture for each channel, but fortunately they were all reasonable.

I'm getting my share of Olympus Mons at the start of the apparition, and the bright cloud remains over the mountain. There is also cloud over the Tharsis Mons and a prominent equatorial cloud on the evening terminator.

Hi all,

Image set from this morning

Bright, prominent afternoon cloud is seen over Olympus Mons, lower left of centre. Cloud can also be seen over the other three Tharsis Volcanoes, Ascraeus, Pavonis and Arsia to the upper left of Olympus Mons. Further cloud is visible on the sunlit limb and south polar region (upper right). I believe the very small North Polar Cap may just be detected in the G image.

 

I have started using an adjusted template format, that will allow me cover most of the apparition as Mars grows (This will make further analysis, or possible composite images easier to handle). At the moment, it may appear a bit oversized with Mars so small, but please bear with me.
