Got a tip on this one from Landru79. Thanks again!

Today's offering, HO-33, is just a little crumb stuck up way north with nothing noteworthy (except for a slumpage half in the shadows). Couldn't even find related SO- or HO- images for it. But again Team, thanks for sharing!

Here's a rough colorization of HAMO 33 from today:



As I understand it, IR and red have been combined and added to the blue channel and then the green is some sort of albedo map according to the color map description here. I've been working on synthesizing a proper green channel from a known blue and red channel for a few months trying to get it as close to correct as possible and this process was used in the image above. Dark pinks are still rendered too orange in the process but it seems mostly reliable in broad use.

Haven't seen this mentioned: There's gonna be a live stream tonight (9 Oct/0200 GMT, 8 Oct/1900 PDT) titled "Unveiling Ceres".

EDIT: Starting now.

The cat-scratches and *poof* from that prominent crateroid are curious.

The terrain folding is pretty interesting. Definitely was interested in seeing this in HAMO. Looks like something flowed across the ground and buckled as it began to stall.

Thanks for pointing that out, I had missed NASA's announcement of the discovery of water on Mars Vesta. (around one hour in)

Summary, please, for those who don't do livestream?

HAMO-34
-- rough remap to orthographic projection to remove camera tilt
-- North UP

This series of images may trend northward between craters Urvara and Yalode and into the fractured continental terrain south of Occator. The montage will be updated as new images come in. Currently the five images in the montage are HAMO-19, -20, -21, -22 and -34.

Newbie composition/location. I hope no disturb

Hamo 35 ¿close shot on "Zadeni"?

HO-36 is situated midway between HO-4 and HO-5. Has a nice flowage in the SE corner.

Presented simply as a purty picher:

Good morning,
someone made a realistic color image of as Ceres appears to the human eye?..Many ThanKS

Today's HAMO-37 is Oxo crater with a different lighting angle ( HO-5, HO-29, HO-37 series ).

Overdue update here.

Edit: Just realized that when I enabled all the layers, I overlapped some labels. I'll correct this tomorrow.

Thanks much for the effort. It is nice to have an updated index map for the raws.

This initial image is a 2x-enlarged enhanced image of the northern portion of HAMO-39 and is shown without the usual descriptive annotations. It is an oblique image and has been rotated and cropped to give a better perspective view.

This spot has to be "Where's Waldo" of Cerean locales. The more you look, the more you see.

--Bill

The current HAMO public image, HO-40, is noteworthy for... nothing. After the formation of the unnamed 100Km crater in the center and subsequent impact cratering this area has lain virtually undisturbed for aeons-- no hydrothermal activity, no tectonic activity and, with the exception of the mass-wasting event from the creation of a 25Km crater on the NW rim, no major slumpages.

This spot is a prime example of an undisturbed area and contrasts very well with the other images in the series across crater Toharu. Good work, Dawn Team.

Polygonal craters are a very important structural clue.




I've ended up using a old database template I used to use for joint and fault orientation. Doesn't do much, but it keeps the data in neat rows and columns and outputs rose diagrams.

--Bill

I know they are releasing 1 image a day--thus the map coverage is filling up very slowly. Anyone know about how many images they actually take per day? By the end of HAMO aren't they supposed to have about 5-10 images deep coverage of every spot on the globe? So does that mean that they are taking 10 - 30 images /day?

Pictures per day is probably a variable, since they are in a nineteen hour orbit. Besides, they store up everything for days and then transmit it all between mapping cycles, so for a couple of days in a row they don't take any pictures.

In any case, they have recently promised on the mission status page that the upcoming issue of the DAWN Journal will have a detailed recap of HAMO, so you will probably get some good answers in a few days.

The only missed pictures were a few from the third mapping cycle. Except for those, I expect every piece of visible real estate got scrutinized at least six times, with some overlap.

HAMO is about to be over. All the picture taking is done and everything transmitted to earth.

In a little over five hours from now, ion engine two will fire up and DAWN will begin its decent to LAMO.

Crater Victa--subject of HAMO-44-- now we can see why this 28 Km crater received it's own name.

The new Occator mosaic looks cleaner than the previous release:
Click to view attachment
However, it's still a merge of long- and short-exposure images, so interpret with caution...

Edit: Oops, sorry for posting to the wrong thread.

And it's still bleached out in the bright areas. We really need to see these locations with a much shorter exposure even if it means the surrounding dirt appears completely black. We're half way to the outer solar system but still snow blind.

It's snow-white and will look wrong if placed in Zone V, or even Zone VII.

It's quite a bit cleaner - great catch!

In fact it's so much cleaner that I'm going to scrap my previous big binary hypothesis and trench for the lessor spot and go with a single large impact for the main spot and lots of secondaries / or a large impact with a shotgun of associated moonlets/fragments.

Specifically I blew up and sharpened the image (I know artifacts are introduced - but it highlights the key features for visualization). Craters and associated ejecta circles are highlighted in various colors. The purple and orange one's centers are a bit sketchy but it conveys the idea. The green one looks like a separate later dark body impact - though it could be pre existing terrain bordering on a fault line.

now the agonizing seven week wait to LAMO to get the picts we've been waiting for - go Dawn go !

The DAWN Journal for October is now out with a complete overview of HAMO at Ceres. They took over 6700 pictures since the start of science operations August 17th. So from there to about October 21st they were averaging about a hundred pictures per day.
The most surprising thing for me was they were able to use some readings from the GRaND instrument to deduce what might be the presence of a magnetic field, although that is far from certain.

And the October Dawn Journal has many new feature names on it's cylindrical projection map. I've updated my Index map, which is good through HAMO-49.

From one of the AGU abstracts:

https://agu.confex.com/agu/fm15/meetingapp.cgi/Paper/74163

Whoa. I missed that abstract. "...ammoniated phyllosilicates mixed with other clays, Mg-carbonates..." is the eyebrow-raiser. But not totally unexpected-- some thought is that Ceres originated in the Oort neighborhood and moved downtown, so it could well be a clinker. And we see similarities in surface features on Ceres and Charon.

--Bill

Ammoniated phyllosilicates.... now that is different.

Plus, the thought of Ceres (and Jupiter trojans) being TNOs is quite intriguing, i.e. we wouldn't have to wait 50 years to sample one.

After 23 years this hypothesis looks to have found a prove.

Hats off and a case of beer to the people who wrote that paper. Amazing.

That was made from Earth observations, not the HAMO observations, so it's in the wrong topic ?

I don't think so. We're just filling in some historical background for the Dawn observation to show that it wasn't wholly unexpected.

Didn't mention it last time but I've since added all of the most recent official nomenclature to the map. I increased transparency in order of lesser importance / size -- ~25% for the smallest, least important vs 75-100% for largest / most important.

Some interesting bright exposures on the central peak in HAMO 50.

Unfortunately the geometry of the shot isn't ideal to really see the steep slopes in question.
