Image artifacts? How can artifacts have a shape of a round sphere and keep rotating around the Sun for over 3 months? Oh wait, i get it, it's NASA...

gee, thanks for coming in late and not reading the thread, DreamerOracle and Cybernet.
Could you tell us what you understand by these words:
- low resolution
- over-enhanced
- jpeg artefact
- 'beacon mode'
- HEP
- cosmic ray strike
Then could you tell us this - HAVE YOU EXAMINED THE FINAL FULL RESOLUTION IMAGES, and COMPARED THEM TO THESE LOW RESOLUTION 'BEACON MODE' ONES, so you can easily see how the cosmic ray/HEP strikes cause the exaggerated artefacts in the initial low-res thumbnails?
The hi-res ones normally come in within a week or two. You''ll know when they are here, because the 'beacon' ones are removed. (Yes, that's right, they'll VANISH!!!, so you better keep copies of these and then you can later claim that NASA are hiding stuff... )
You can see all this explained, including examples, in quite painful but simple detail, earlier in the thread.
But don't let that stop you guys posting redundantly...

The SPHERE if you've looked at it ISN't pixelated.
Its within the corona
and even has a spherical shading from its intense proximity to the sun.
You need to check it, play with it if you like but that SPHERE won't vanish.
Just because you can explain a possibility for some of the specks and spots it doesn't mean you've debunked it. Its a SPHERE.

Well, this is going to be rather embarrassing for you...
May I suggest you read what follows VERY carefully before you make another gaffe like this one..
First up, you'll note that I TOLD YOU that the low resolution images would disappear. And guess what, they HAVE - gee maybe I knew what i was talking about... Anyway, that means that the high-resolution images are now up. Just return to the site and find the matching image, according to the date and time tag on the LOW-RESOLUTION BEACON-MODE one you initially posted.
Now compare the images. First up, you will notice the new one is VERY OBVIOUSLY MUCH HIGHER RESOLUTION, unless you have severe vision problems.
Secondly, you can now look at the HEP/cosmic ray strikes and see them for what they are.. NOT 'spheres'.
The SPHERE if you've looked at it ISN't pixelated.
I see no sphere, just a few pixels with sharpening and jpeg artefacts around them, just like the rest of the image. And if you look at the high-res images, you can see exactly where the artefacts come from. It's not rocket science..(oh wait, I guess it is..)
Its within the corona
What a ludicrous assertion - is this a 3D image for you? You CANNOT POSSIBLY DETERMINE THE DISTANCE FROM THE CAMERA. As you will see from the HIGH-RESOLUTION image, it is in fact a tiny spot caused by a particle/ray strike on the sensor. Very common.
and even has a spherical shading from its intense proximity to the sun.
You seriously see a 'sphere' there, do you? Forgive me for not using you for any future forensic image analysis...
You need to check it, play with it if you like but that SPHERE won't vanish.
As I demonstrated earlier in the thread, with just a few simple steps YOU TOO could duplicate the artefacting in the low-resolution images, simply by using the high-resolution REAL image, reducing its size, and sharpening it. Which is exactly what the beacon-mode image is.
Would you like me to link you to the posts, seeing you are too lazy to actually read the thread???
Just because you can explain a possibility for some of the specks and spots it doesn't mean you've debunked it. Its a SPHERE.
Just because *you* desperately want it to be an alien spacecraft or some other exotic phenomena, doesn't excuse your lack of knowledge of this spacecraft's operation, along with a lack of knowledge of digital imaging.
By the way, in your initial image you screwed up the linking, so I cannot guess what image that was. However, for future reference, you can try this.. When NASA posts the initial low-res beacon images, the link looks like this:
stereo-ssc.nascom.nasa.gov/browse/2010/04/18/behind/euvi/195/2048/20100418_173530_n7euB_195.jpg
(that was one of the pics posted by cybernet and has now gone)
But the high resolution version that replaced it is right there in the same directory:
stereo-ssc.nascom.nasa.gov/browse/2010/04/18/behind/euvi/195/2048/20100418_173530_n4euB_195.jpg
Soory for the non-link - ATS's url function choked on it for some reason - copy and paste it if you wish to try it. And note the tiny change in the filename to denote high-resolution - all you have to do is replace the "...n7euB..." bit, with "...n4euB..." instead. 7 means low-res-beacon-mode-temporary image, 4 means high-resolution-final image. (Or you can always just use the search function to look the image up again.)
Go on, test this all out. Check the very latest (beacon-mode) images - save them (so you will have all the numbers required to get the later images), then wait for a while. When the link no longer works, replace the 7 with a 4, and then compare the two images at full resolution.
You'll get the hang of it, and you'll see results like this comparison I showed earlier:
Try the same techniques on *your* images.
And for the sake of completeness, here's NASA's notes on the topic:
stereo.gsfc.nasa.gov...
If you have any MORE questions about how the Stereo spacecraft works, or digital imaging, or cosmic rays and HEP's, feel free to ask.
And maybe next time, try doing your homework FIRST.
