Seeing was a little above average, but not quite as good as the previous week.   In these images you can see Olympus Mons setting at upper right and Elysium Mons rising at upper left (in the north-up images).  In Tharsis, Ascraeus Mons is visible, and Pavonis just barely, but Arsia is covered by the usual thin clouds.  There are some interesting dark features peeking out from under the north polar cloud hood, but I'm not sure what they area.  Mars has been pretty much dust-free this apparition, hasn't it?  Is that normal for this time of year?

Fantastic detail!  Thanks for the capture info.

 

I believe the features on the NNE limb in the 10/23 0255UT view are the outskirts of Alba Mons.

 

In your 10/22 0518UT view, the dark lineation along the limb may be Arcadia Planitia and the Propontis hills, with Erebus Montes inset from the northern limb, just west of the central meridian.

 

Those are my best bets.

Excellent Kevin bow.gif  Both sets are great but the images on the 23rd have the edge waytogo.gif
