If it's more like a disk than a ring that is rotating togther with the star-sphere...that's an icon depicting the Arecibo radio telescope. It's shown at the position right above the (fixed) dish in the star sphere.
If it's really a ring (hollow) ... I absolutely have no clue, tho.
It is a fairly thick hollow ring (looks somewhat like a washer). It only appears occasionally, then quickly disappears. When I see it next, I will try to fix the location and time.
This is very strange. I picked it up again last night. It appears to be a mark of the zenith position of the sky over a certain spot on Earth, about 18 to 20 degrees north latitude and UTC+3 hours (somewhere in Arabia). It slowly precessed eastward as time went on. I saw this on the computer that was running a lot of Arecibo Binary Pulsar searches. My other one was running all Global Correlation searches and the ring did not appear on that.
There is supposed to be an orange reticule (two concentric rings and a cross) marking the sky position currently analysed, nmaybe what you see is a display error while drawing the reticule. It would be interesting to note whether the reticlue is displayed at the time you see the "mystery" ring
Every once in a while I see a large white ring appear on the StarSphere Screensaver. I was curious as to what that represents.
Thanks,
JD
Hi JD,
your not alone in seeing that white disk, i have seen it on two occasions in the last few days, it seems to stay there for part of, or a single rotation of the star sphere then dissapear as the sphere rotates, i ignored it because i thought it was part of the normal graphics, now you got me wondering, lol.
Bikeman, yes in my case, the orange reticule was displayed at the same time in another part of the Star Sphere!
Just a thought, if images can be posted here???, and, if this white disk appears again on my computer, then i will grab a screen shot of it and post it, you guy`s in the know might better explain what it is if you can see it for yourselves.
I have confirmed that it only appears when the StarSphere is showing the Arecibo Power Spectrum graph in the upper right-hand corner. It is not actually a ring at this point, but an almost totally filled-in circle with a small hole in the center and three spokes emanating from the center of the circle. I am not sure what kind of symbol that represents, but obviously some programmer got creative with displaying it. It would be interesting to know which location on Earth this is centered on.
I'm not aware of any deliberate code which ought produce that. The screensaver is OpenGL based, which is a generalised rendering machine, so it might be an artifact of a given implementation.
[Aside]Hmmmm .... about 18 to 20 degrees north latitude is in the ecliptic plane for a northern summer. Mars is nearby at the moment. Mercury is about to transit the Sun. Who can say ? Keep a careful eye on the screen and have a baseball bat ready in any case ..... if you survive, let us know. :-) :-)[/Aside]
Cheers, Mike.

I'd put this down as a rendering issue with the Aricebo symbol. Without looking at the code, I reckon it's an ordering issue - the sequencing of drawing with respect to some transform ( ? scaling ).
Cheers, Mike.

White Ring on Screensaver

Aahh. I think this is an attempt at rendering the Aricebo symbol ( which is like a Mercedes Benz emblem ).
