Hello all

here is Mars from last night.
Seeing started out terrible but slowly improved over an hour and a half. It might have been local conditions becuase the day was quite warm and night quite cold so I suspect it was just to do with temperature gradients of the mirror, or perhaps the ground etc.

Anyway, eventually I was able to get some good detail.

Elysium was bright but not exactly cloud-covered. Instead it presented two distinct streaks with a somewhat yellow hue. Possibly dust?
Phlegra, Trivium Charontis and Cerberus create a sweeping diagonal boundary to the edge of Elysium, they are on the Central Meridian.

Olympus Mons was sporting a large white cloud which produced a significant bulge in the sunset limb mist.

Mist was noted on both evening and morning limbs which was pale blue compared to the brilliant white polar cap and the yellow streaks of Elysium.

I noted a dark collar around the polar cap which was darker towards Utopia. I also noted ice outside the collar over the central meridian.

Mare Cimmerium was the darkest region on the disk, Tritonis sinus especially so.

Good observing report and a very nice and detailed sketch. The yellow hue over Elysium was probably dust. Nice on observing the cloud over Olympus Mons. Thanks for posting the sketch and report.

Chris,

A beautiful and accurate observation and report over this longitude of Mars that contains fewer albedo features. The yellowish streaks over Elysium may be dust and we need to monitor this in the future. I agree with the color of the desert regions and dark albedo features. Thank you for sharing it with us all.

Regards,
Carlos

Very nice work Chris. A lot of subtle blendings bring the whole piece to a fine point. I'm glad that 12" is working the magic for you. The isolated Maria in the vast deserts has been well portrayed by a lot of folks this apparition and you do it well here too.

Very nice work Sir!

Pete
