Hi All,

 

I was up yesterday early in the bitter cold, and ignored Saturn, as I wanted to throw the kitchen sink at Mars.   The region called the Mountains of Mitchell, or Novus Mons, that starts to separate from the SPC, around Solar Longitude 260 degrees (we are now at 263 degrees)  was roughly face on.   I hoped to pick it up as a separate patch of white from the SPC.  Unfortunately, I was unsuccessful - seeing was not ideal and there was a 25 minute interlude of fog that came and went, blowing a hole in the session.

 

Here are the results. Maybe another crack at it tomorrow.

Mark

Yes, I think picking them up this early with Mars size etc is pretty demanding Mark...winding the clock back 12 years and talking about this SPC aspect reminds me of Chasma Boreale on the Northern Polar cap, when it was in the spotlight...

That's interesting - were you or others able to image it then?

A follow up image from this morning - still not visible to my eye, though quite good seeing. I won't be able to have another go till the weekend, by which time the relevant face is slipping away.

What percentage of images is this - you could try a much smaller fraction (even at the risk of getting a slightly grainy image) to sharpen things up. I usually use my 3% or 9% stacks, but sometimes the 1% is noticeably sharper.

5% Nick. I might give 1 and 3% a try. I have 8 x 3 min colour videos to combine in WJ to take care of noise. Thanks for the suggestion.

By the way, Richard McKim thinks the Mtns of Mitchell/Novus Mons feature may have evaporated now, perhaps a few days before it came into view for me.

Go here https://alpo-astrono...ing_Mars_3.html and scroll down to "MARTIAN SOUTH POLAR CAP PERIPHERY" for the details of the Mountain of Mitchel.

Looking at your ALPO-Japan posts Mark, it appears you caught the 'Mountains of Mitchell' break in the SPC back on April 15 and 17. Clyde Foster has some images of it around the same timeframe.

...if you're referring to me Mark and Chasma/Rima Boreale/Borealis then "yes" - others did so also...here's an old archived thread where I posted some images https://www.cloudyni...anali-on-mars/  and also the link to them (first, then those right near the bottom) in this page of our website:  https://momilika.net...ages/Mars.htm  

 

There's a Viking image of it on the page Jeff linked to also...

Thanks for all the extra likes and interesting follow-up comments.  Sorry for the silence - fairly intense family activities here as we move a relative into a retirement village.

 

But yes, I can see what you mean John about my ALPO images. And my reading of Jeff's site  indicates to me that I had somewhat misunderstood the timing of changes to the Mountains of Mitchell region. I will read and absorb the materials and if I can I will post some updates ASAP.

 

More soon I hope

 

Mark
