Why doesn't that filter affect the other spots allso? All the smaller spots are brighter in the higher resolution.
Could the elevation angle of the Sunlight (seems lower in the low-res picture) be part of the explanation (illumination and reflection of brighter slopes, like on lonely mountain)?

There are lots of factors that are causing differences between those images. Different capture angles will receive differing amounts and positions of reflected light, different solar incidence will change the amount and position of reflected light, different exposure lengths will record the area differently, image compression can play a role, and finally image processing such as the histogram stretch and other filters can greatly change the appearance of the data.

Here's a rough modification of the higher resolution capture to appear more like the previous one.



I could say I'm hopeful that the area at the far right in the survey orbit image is evidence for the 'haze' that disappears in the HAMO image but I think what we are seeing is more related to Dawn being closer and better able to resolve the spots than anything else. Most likely, any images featuring the supposed 'haze' have not been released, unfortunately...

It looks very much like the longer-exposure image was used for the smaller spots (as it was for most of the new image). Only the largest spots were replaced with the short-exposure image. They may have simply selected by hand which parts of the long-exposure image to replace with the short-exposure image, or perhaps used some semi-automatic selection method.

We really can't say much from this new image and have to wait until we see the original two frames.

As I said in the caption to the Comparative images of the two timeframes:

And looking closely at the floor of Occator in the HAMO image, I can say that there has been no obvious changes in the 9June to 21Aug time period, although this has been a very active area.

Imaging map:

This linear structure from that image seems to have a depression along part of its ridge line. It appears to be due to subsidence of whatever material formed the dike in the first place.

In the context of SO34 (http://photojournal.jpl.nasa.gov/catalog/PIA19603), it is a part of a ridge, but it even looks as if it could be the central peak of a much wider/less obvious crater. You will have to rotate HAMO16 90 deg counterclockwise to get the same perspective.

ZLD: could you please add SO34 to your awesome map?



EDIT: I almost forgot, this is also visible in a different lightning in SO43 (http://photojournal.jpl.nasa.gov/catalog/PIA19616). The flowage features from the crater on the right ridge are more obvious here.

In your enlarged version, it looks very obvious that there are boulders on the floor of the young, intriguing crater; but in the original image, it just barely looks that way. Hm.

bsharp: I'll try to include this in today's map. The Dawn releases have pretty commonly been occuring between 11h00 and 12h00 CST.

Habukaz: As for the magically appearing boulders, I wouldn't rule out the possibility of noise but most of the released HAMO images seem to be, for whatever reason, just slightly out of focus to begin with so who knows.

I just had a look at the TIFF file, and it seems that JPEG was the culprit. For such fine details, even light JPEG compression can make a big difference, apparently. Lesson learnt.

Pretty sure now that the boulders are real. I hadn't noticed boulders earlier, though I had only been looking at the JPEGs. I can see boulder-like structures in HAMO #6 as well now.

There is so much happening in HO16. An apparent slumpage feature to the west, a mantling terrain flowage feature to the east and on the upper side, a conical hill with a central pit.

And we are getting the "Meh" HAMOs from last month. Think of what the reaallly good stuff shows!!!!

No kidding Bill. I think at this point, while the brights spots are tantalizing, Haulani is currently more intriguing to me. Really looking forward to that HAMO image. I will again hope that's what we'll be getting today but I'm not going to hold my breath (not interested in asphyxiating myself really).

Also, the conical hill you noted in your image Bill, there are several others in the area and to me it would seem that they may be related to ancient central crater peaks that have lingered longer than the crater rims.

Spectacular slump feature in HAMO17:

Now that we've seen an appreciable number of slumped soil in HAMO, this one seems particularly smooth, with an obvious exception that it was already unique. It seems almost like it just melted away like a lava flow rather than the other seemingly stepped mass wasting at other sites.
