Geomagnetic Storm In Progress 110

Posted by Soulskill from the sky-is-falling dept.
shogun writes "The National Oceanic and Atmospheric Administration reports a strong geomagnetic storm is in progress. The shuttle, ISS and GPS systems may be affected." They think this storm was caused by a weak solar flare on April 3rd. As you may expect, this has caused some unusually impressive northern lights since it started. What you may not expect is a photograph from Japanese astronaut Soichi Noguchi aboard the International Space Station showing the aurora from orbit. He apparently tweets a lot of pictures from space. He and his crewmates have taken over 100,000 pictures since coming aboard the ISS.

    From this you can see that the green glow is low and the red glow above it and diffuse. Without the obscuration you could get a better idea of the pattern of the intersection of the magnetically guided particle stream(s) with the atmosphere.

        The EXIF on that photo says 13 seconds at ISO 200 and f/2.8 with a Nikon D2Xs. Even though that camera is a 2006 model, I'd think it would have been able to take acceptable ISO800 photos which could chop that exposure down to about 3 seconds or so. I'm going to assume that the camera was modified to remove the Near IR/IR filter, but if not, that would definitely help the reds come through better.
