Hi All,

Just wondering what you think these are?

They could be image artifacts.

I guess we'll have to wait until (if) NASA explain...

Could it bee a software glitch, a buffer problem, there seems to be a dark patch right next to a bright patch, looks odd. Like light was taken from a section of an image and put over pixels right next to it. My bet goes on a software glitch in the system somewhere.

If you click "caption" against any image in

stereo-ssc.nascom.nasa.gov/browse/2010/0...ahead/euvi/195/2048/

You'll find "Because of the high amount of compression used for the space weather beacon,
the image quality is far lower than in the final science product."

Now, "Lower quality" can be read "higher noise" - that noise can look like anything.

Look at a jpeg of the moon or something with compression turned up and I'd expect to see some detail that isn't really there.

Did Stereo ever capture a real transit?
Might be intresting to compare.
Image artifacts are my guess.
But how cool would it be to have
Aliens living in planet sized spheres in the Suns Corona!?
What a holliday destination!

Good question Frank - made me do a quick search

The Moon

Mercury (though not across the disc)

Copy your links (which are different from what is displayed) and replace n7 with n4.

Looks like they updated the page today.

Can't say that I remember enough of the images (except artifacts) to compare but the images now look cleaner and the caption (via the link I posted) no longer makes reference to reduced quality due to data compression.

Fresh video



Any ideas?

Looks BIG compared to the sun!

If its a satelitte closer to the earth, would it have 'wings' that small?

my money is on an earth satellite, Mercury would be a similar-ish size on the disk of the sun.
As for the wings (I presume you mean solar panels), some satellites have the solar panels on its walls,

Looks like a tumbing satellite to me.

I timed the transit and found the duration to be 29s.
The Sun's angular diameter is about 30"

I used a CD to draw a circle and I played and paused the video and plotted a course.

Length of transit 10.7cm
Equatorial diameter of disc = 12cm
This was drawn parallel to line of transit.

Angular speed was then calculated to be 0.92 arcsecs per second.
A sidereal second is 86164/86400 = 0.9973 seconds of wallclock time.

Rough enough calcs but my money is on it being a geostationary satellite.

At first glance, I thought the video was showing a massive white circle moving across the sun :blush:

Thinking about my post more.

For the object to be geostationary - and cross the disc of the Sun - the image capture would have had to be at or near one of the equinoxes (me thinks). I have no information on date of capture so can't progress that line of thought.

I think it's time for me to climb out of the rabbit hole...
