Here's an image from last night captured in average seeing and variable transparency. What's interesting is that there appears to be a new outbreak in the northwest of this image, between Xanthe and Tharsis.

 

UT 07:22

I also see it as a bright region in Tony's image from an hour earlier:

My image was captured with a Nexstar Evolution 9.25 + 2x Barlow & ADC. ASI224MC camera.

Nice image! I think I see those bright areas in my image from the 22nd as well.

Nice result, Ray. Thanks for pointing out the same feature in my pictures. I noted the bright area but had not the chance to double check whether it was an albedo feature. I posted another IR pic at 05:14 UT where the feature has rotated into view.

Thanks, John. I think you're right, but they're a bit north and east of where they are in mine.

Looks like a sizable dust cloud to be south of Lunae Lacus covering part of the Ganges.  Nice image.

You're right. I had imaged on Nov 21 0917 UT and it wasn't present,  but it's clear in my image from Nov 23 0905 UT. I  Here's the image comparing the two that I just posted.

Here's a nice animation of a dust storm in the same general region as seen by Mars Express in 2011 - https://www.planetar...empe-terra-mars

 

Ray - you have a very keen eye for spotting an outbreak!

Thanks, gregg. I guess I spend enough time on processing that I notice when something looks different. Here's my comparison of Nov 20 with Nov 24:

As well as the bright spots, a couple of the darker spots where the dust originated look softer in yesterday's image. (South of Tempe? Nilokeras? I'm not so good with albedo names.)

Nice observation. I took a shot last night and something look off when I did the initial processing, suspected a dust storm. Different region, though.
