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.

    NOAA's Space Weather Prediction Center [noaa.gov] has a bunch of data on the storm, including the estimated 3-hour Planetary Kp-index [noaa.gov], and a bunch of other data [noaa.gov] and alerts [noaa.gov].

    A readable description of the relationship between geomagnetic events and aurora can be found here [noaa.gov].

  • But I'd love to see it without the vehicle obscuring it. It would help to get a better visual grasp of the structure of the aurora itself.

    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.

          No, not really. Its a giant ball of fusion, photons, plasma and gases that is 99.8% of the solar system's mass that is doing all kinds of crap under the surface that we can't see. Hell we don't really know what is going on down there under the surface.

          Why can't this giant ball of fusion have a medium sized solar flare this week without it being beyond the realm of possibility?

          What else would this be other than a solar flare?

          • by unity100 (970058)

            because it is TOO big to be that irregular. imagine, a huge ball of fusion, will stay silent for close to a decade, then just pop a single strong flare once, suddenly, 'hailing' a new era of activity.

            this is sun, a ball of fusion as you noted. not earth with its tectonic plates and a handful of existing outlets for magma trying to find its way out.

                  That is after all, what is being measured here. The prefix 'geo-' in geomagnetic storm the article is talking about means 'Earth'. That is where the field is coming from, the Earth. The sun is simply throwing charged particles into that field, again from the Earth, at a rate that hasnt been seen since 2006. This is producing storm level flux for the first time in a few years in the Earths' magnetic field

Why do some disaster areas result in looting and rioting and others remain calm? You can't really compare disasters but a global strike like this would be easier to compare. Would there be riots all over? None at all? Only in certain economic areas? Or (oh boy I am going to get it for this one) does it depend on race? Culture? Local leadership?
