    Protons and electrons, cations and anions, current, ….the solar battery it is not being charged properly, have to revise the alternator.

    The same rate of decline as seen in the Livingston & Penn magnetic rate decline perhaps ? And a related cause ?

    Just the general weakness of the sun in the current cycle. We should be at the max of solar cycle 24, but there is continued weakening of many parameters. Is this the start of a Dalton minimum? We are already over due for declining temps from the Milankovich cycles, so looks like cooler temps ahead despite CO2.

    … so looks like cooler temps ahead despite CO2.

    Translated: “… so looks like nothing is in the way of cooler temps.”

    I need leif.

    I have difference
    (Swepam / ACE) date
    and
    (OmniWeb)
    27 days Averange
    Why?

    Hi Michele,
    I have emailed Leif for an opinion. I will let you know the reply here.

    Here is Leif’s reply:

    The ACE spacecraft is ailing [and failing]. The density data are not
    reliable. You may also note a strong [artificial] variation with
    almost a 6 month period [not quite 6 months, a little bit faster like
    5.9 months]. Probable related to the halo orbit that the space craft
    is in.

    Michele,
    Some confirmation of Leif’s information here:

    Thanks Roger and Leif for info now,
    I read paper

    You might find insight in this http://www.leif.org/research/Svalgaard_ISSI_Proposal_Base.pdf because it outlines thinking today.

    Michele, we know that the solar polar magnetic field has weakened over the past few years…

    We also know that Earth magnetic field has been weakening over the last century…
    http://www.geomag.bgs.ac.uk/images/dipole_mo.jpg

    Currently mainstream science conjectures that both sun and Earth polar fields are produced by an internal dynamo(s), so it looks like this could be a problem coming from outside the solar-system?

    The recently observed weaker solar wind is an indication that the sun is producing less photon charge to drive as many protons to escape velocity, I think this is a first symptom of a long-term reduction in solar activity and over the next few years we will observe a gradual but sustained fall in TSI. In short, there is a good chance another Maunder Minimum is on its way.

    1410-1500 cold – Low Solar Activity(LSA?)-(Sporer minimum)
    1510-1600 warm – High Solar Activity(HSA?)
    1610-1700 cold – (LSA) (Maunder minimum)
    1710-1800 warm – (HSA)
    1810-1900 cold – (LSA) (Dalton minimum)
    1910-2000 warm – (HSA)
    2010-2100 (cold???) – (LSA???) – (The Eddy Minimum)

    @ Rog & Tim

    Approximately, 1990
    Jump ascendant solar wind flow pressure
    What has changed ?
    It looks like a switch…
