Got the time to elaborate on that some, Dr. S.?

Got the time to elaborate on that some, Dr. S.? The Earth's magnetic north pole is drifting from northern Canada towards Siberia with a presently accelerating rate — 10 km per year at the beginning of the 20th century, up to 40 km per year in 2003, and since then has only accelerated." |

If such is the case why is that phenomenon not reflected in the Auroral Oval which is nice and round ? See for your self. www.swpc.noaa.gov/pmap/pmapN.html |

Good look at your link shows that the Aurora is strongest not where the NP is suppose to be, but at a sector just above 60N and is inclined towards 180 longitude since 260E Canada and 110E Siberia, are separated by 150 degrees, and opposite side by 210 degrees, at the ionosphere height fields merge into a torus rather than a bar shape, hence shape of the Aurora. The aurorae is strongest in an oval around the magnetic dipole [somewhere north of Ellesmere Island] as it should be. Bob is correct. |

Vuks image, Looks very much like an " Electric Quadrupole." I didn't say, "Magnetic Quadrupole," I said Electric. My family background does not include solar/astro physicists or engineers but Millwrights. I just want to diagnose and fix this. lol You are too easy to fool. [or you don't think much for yourself]. In your electric quadrupole there is one maximum [red] in the north and one minimum in the north [blue], but that is not what the geomagnetic field looks like; for that there are two maxima in the north. |

Mind you it's been a while since I studied this stuff and haven't used it much since but I'd say that Maxwell's Equations are taking a little bit of a beating. |

And here is polar view of the big ball of ‘wobbly jelly’  Hi vukcevic Where is hidden Dr Svalgaard on his thread ? There is no date on this map. Which date ? Impossible to find the website where it comes from. This link isn't correctly written you made a bad "cut and paste" www.eri.u-tokyo.ac.jp/kokusai/eng....ure20100506.pdf |

Doctor Svalgaard, Why does the occurrence of solar flares always seem so surprising? Aren't there any reliable precursors? For example, back in 1975, Lang noted "dramatic" changes in the polarization of solar radiation at radar wavelengths (3cm and 11cm) an hour or so before a flare. Kenneth R. Lang, 'High Resolution Polarimetry of the Sun at 3.7 and 11.1 cm Wavelengths', Solar Physics, vol. 52, Apr. 1977, p. 63-68. www.springerlink.com/content/w43237361118280x/fulltext.pdfIs this phenomenology still being studied today? Did these variations turn out to be false alarms? I'm also curious why there seems to be no high-resolution imagery ('passive radar maps') of the solar disk at these wavelengths. All the interest seems to lie in the EUV and x-ray spectrum. Even back in the 70's Lang and others were able to resolve these 'radar' features down to a few seconds of arc, sufficient for resolving sunspots. [Maybe such imagery exists. I don't recall seeing any] Terrestrial radar maps (active) have been exploiting this kind of polarimetry for classifying surface features with great success. Why wouldn't this reveal useful information about the sun? I think it would be interesting to observe such a map right now, with the SFI at 86, and one large spot starting to crawl off the Western limb, to see where all the solar activity is coming from. Is 11117 doing all of the 'heavy lifting' of the SFI right now? |
