with a not very well fused nadir (i.e., not separately patched) (and other slightly mis-stitched areas elsewhere. I think this is before I recalibrated my Samyang 8mm so that it could actually focus properly). [Ian Tindale, Feb 19 2016]

       My wife and I saw the ISS go by yesterday evening — the second time I’ve seen it.   

       One question — which direction on a space station is “atop”?
Ian Tindale, Feb 19 2016
  

       On the ISS, the top and bottom are referred to as "zenith" and "nadir", with the "nadir" direction being pointed toward Earth at all times, and that's the side with the multi- windowed cupola on it.

       ^ Correct   

       // My wife and I saw the ISS go by yesterday evening //   

       Were you in a parking orbit, then ?   

       // the "nadir" direction being pointed toward Earth at all times //   

       The irony of that statement is breathtaking...

       That’s interesting. When I shoot the components that will become a full 360°x180° panoramic photo, the nadir is the bit where you end up photographing your feet, or the tripod, so you have to step aside and do a “nadir shot” and often artificially patch it in.

       // a full 360°x180° //   

       64,800 degrees ? That's one really smart photo ...

       It’s pretty hot.
Ian Tindale, Feb 19 2016
  

       Or a hot one. Never predicted Ian as a supermodel. Sorry Ian...

       If this would work, it is a brilliant idea.   

       If not, please disregard the foregoing.

       It does seem like the total number of degrees or degrees^2 would be 360*^2 or 129,600.

       If it was an ISIS weathervane would it feature a headless chicken? (Probably not in good taste)

       I'm not entirely certain, but if the solar wind were "blowing" hard enough to affect this device, the astronauts and cosmonauts within would have received a fatal dose of radiation.
tatterdemalion, Feb 20 2016
  

       [WcW] - you're on the right track: it's actually 129,600 / pi square degrees in a sphere; or about 41,253 deg^2.
lurch, Feb 20 2016
  

       // a fatal dose of radiation. //   

       Not necessarily. The "solar wind" which gives rise to auroral phenomena consists mostly of charged particles, not energetic photons, and can be blocked effectively by a very modest thickness of metal.   

       The danger arises more from "cosmic rays" which are ionizing and highly penetrating photons.

       It'll need some sort of scrolling read-out so the cock can doodle too.   

       // which direction on a space station is “atop”?// No gravity: it's all "atop".
