Anomalous SOHO images Jan 2004 and Jan 2005

[Lianachan]

Found this story (http://www.unknowncountry.com/news/?id=4354), concerning the appearance of two strange looking anomalies, a year apart, on images apparently from SOHO. I can't find any mention of these on the SOHO site, however. I was wondering if there was any discussion here about last January's image, and what the general opinion on it was. If this second image, or the whole thing, is new to anybody then what do you think accounts for them?

Those are...

Odd...

I actually don't see anything wrong with the first picture. I'm not entirely sure what that webesque line is in the second one, though.

I don't know what "webesque" is, but if you are referring to the dot with the horizontal line in the upper right quadrant, it's probably a planet. There have been similar photos in the past - when for example Venus gets in the frame, it's so bright that it overwhelms the detectors and you get that little line feature.

Picture 2:

I see a dot which appears to be overbright (I saw similar artifacts on recent heatshield photos by Opportunity) and 2 redish lines departing from it. So the white part is "something" too bright (a planet or something, I wouldn't know, i'm not into these pictures). I have no idea what the lines are.

I see nothing wrong with the (BEAUTIFUL) first picture. There is a whte dot on top, but as it is just a hite dot I have very little to say about it.

Nothing new (http://www.badastronomy.com/bad/misc/planetx/soho.html), despite what the fringe claims.

Okay, just discussing the second image then...

If that were a planet, wouldn't it be in more that one frame? They are taken only ~24 minutes apart I believe.

Yes. There's a page posted listing transits (http://ares.nrl.navy.mil/sungrazer/transits.html), and nothing appears to be passing by during that time. Here are examples of planetary transits: Venus (http://sohowww.nascom.nasa.gov/pickoftheweek/old/10jun2004); Jupiter and Mars (http://sohowww.nascom.nasa.gov/pickoftheweek/old/23sep2004).

Mr. Strieber is on yet another wild goose chase. Much ado about nothing.

Excellent, thanks. I realised they had to be problems with the imaging, but wasn't sure of the mechanism by which they were created. I'd never read that part of the site before!

In that second image (http://sohowww.nascom.nasa.gov/data/realtime/javagif/gifs/20050102_1230_c2.gif), what could be so big and move fast enough to not be in the previous image (http://sohowww.nascom.nasa.gov/data/realtime/javagif/gifs/20050102_1206_c2.gif) or the next image (http://sohowww.nascom.nasa.gov/data/realtime/javagif/gifs/20050102_1254_c2.gif)? And what do you suppose those two lines are?

Deathrays obviously. They must have thought we lived on the sun and not little obscure blue/green rock third out. Haha, we luck out again.

Since there's nothing of the sort in the previous/next frames, there's no need to presume that there's any large, fast-moving object present. Perhaps videos from Jan. 2nd might help better illustrate:

LASCO C2 (http://lasco-www.nrl.navy.mil/daily_mpg/050102_c2.mpg)
LASCO C3 (http://lasco-www.nrl.navy.mil/daily_mpg/050102_c3.mpg)

And what do you suppose those two lines are?

My guess would be some sort of artifact, although they're not entirely inconsistent with debris streaks that have shown up from time to time in the past.

Regardless, certainly doesn't appear to be anything of consequence.

There's no planet in that spot (thanks, Celestia.exe and the date/time stamp on the photo).

Not being in the next/prev frame, and being overexposed and sharp-edged rather than a shadow or crescent, I'd say it's a cosmic ray. There are a lot of white specks in the picture--this one just happens to look like something.

If there was an object there, it would be brighter than the sun's corona, enough to overexpose and bloom.

jan 04 is beautiful. It has replaced titan as my desktop background :)

Not really, no.
