here it seems that protons temperature K follows speed and ap index Of course it does as the solar wind is basically due to the expansion of a hot corona: the hotter, the faster. So causality is: hot corona => fast solar wind => more agitated geomagnetic field You may also note another relationship: a fast solar wind is a less dense solar wind, that is the density is low when the speed is high. This also has a simple explanation, as a parcel of the solar wind covers a larger volume when it flows faster, hence giving a lower density. |

Bernoulli was right again?
We need a solar wind wing. Make the wind faster over just one side.

Yes, except that the solar wind is MUCH more variable than the Earth's atmosphere. |

The variation of the magnetic field. What makes the magnetic field vary? The solar dynamo What makes the dynamo work? Circulation of solar plasma Why does it circulate? Because of solar rotation and subtle temperature differences How does that work? 'it is turtles all the way down' en.wikipedia.org/wiki/Turtles_all_the_way_down |

I thought about that for a long time according what a physicist explained to me ! I told to my mind that perhaps "electrons" that turn around protons are the explanation. But I don't see the choice for "electrons" on DMNI2 to check it ! |

The field of Helioseismology is a promising tool for this and we shall in due time learn what is needed to guide the theory. |

The electrons are an effect and not a cause. |

Paper is in the works. This always takes time. The essence of L&P is that the dynamo is still working as usual [as it also did during the Maunder Minimum], but that the generated magnetic field does not concentrate enough to form visible spots. So L&P is not claiming that the dynamo shuts down. |

For what it's worth; strange but true: A turtle is also central to an Iroquois Creation story. The story appears in a publication by the Bureau of American Ethnology, around 1900. No, Pooh is not that old. ;D |

Leif does the USAF, or anyone else for that matter, compile records on the rate at which new regions are numbered versus when they fade and dissappear ? What I'm think of is a Net Formation of spot regions. When more form than those that disappear the number is positive. When the disappear faster than they form it's negative. Such an indicator would give us some clues about where we stand in the Cycle although this figure would have to be averaged to provide a degree of reliability.
