Scientists Stumped By Sun’s Asymmetrically Reversing Magnetic Field

April 27, 2012


The Sun’s magnetic field is reversing, South becoming North, as it does approximately every 11 years on a cycle, but this time, something even stranger is going on: The North is moving much faster than the South, and space scientists aren’t sure why.

“Right now, there’s an imbalance between the north and the south poles,” Jonathan Cirtain, NASA’s project scientist for a Japanese solar mission called Hinode, in a recent article on NASA’s website. “The north is already in transition, well ahead of the south pole, and we don’t understand why.”

Further, the asymmetrically reversing solar magnetic field could have an effect on Earth, resulting in increased solar flares and the accompanying bursts of radioactive particles called “coronal mass ejections,” or CMEs, that can hit Earth and cause brilliant Northern Lights displays and problematic geomagnetic solar storms, according to NASA scientists.

“This usually leads to a double peak in the sunspot number and CME rate as a function of time,” Nat Gopalswamy, a solar scientist NASA’s Goddard Space Flight Center in Greenbelt, Md., in an email to TPM.

Gopalswamy and his team studied the Sun’s shifting magnetic field frommicrowave signatures obtained by Japanese radio telescopes and reported their findings in a paper in the Astrophysical Journal on April 9.

Gopalswamy explained that while the Sun’s shifting magnetic poles were first discovered in 1955, the rate at which the North and South wasn’t found to be mismatched until the last few solar cycles.

To be clear, the magnetic field doesn’t just flip, but rather, the Sun essentially sheds its current magnetic field and regrows a new one every 11 years. Currently, the Northern portion of the Sun is further along on this process than its Southern counterpart.

Further, the Sun’s oddly shifting magnetic field affects the Solar System, though it isn’t yet known just how.

“Whether the north pole of the Sun has north or south polarity decides the entry point of galactic cosmic rays into the heliosphere,” Gopalswamy told TPM.

The heliosphere is an enormous magnetic bubble made up of the continual regular ejection of charged particles from the Sun. It stretches beyond Pluto.

    The entire solar sysem is being deluged with neutrinos. This deluge is not only heating the gas of Fluff of which our solar system, possibly one of many, is embedded; it is expanding and therefore compressing our heliosphere. The neutrino deluge is also heating the cores of the planetary bodies. This heat is held captive as it cannot expand while the heliosphere is undergoing this ‘shrinking’ down closer to the sun. An analogy would be the lid on a heated pressure cooker. Further out the heliosphere no longer exists as it has been contracted toward the sun due to compression. This is why the heated cores of planetary bodies can radiate the heat upwards and produce such things a oases and liquid where formerly there was none. All this temporary compression will vanish when 2013 arrives.

    Is a body of antimatter briefly broaching the ORT shell shedding massive neutrinos before being repelled? OR is the Milky Way a giant capacitor storing charge up to saturation and then will discharge in an energy pulse currently misinterperted as a run away black hole? OR is it both?

    this could be part of the prosess that a black hole puts its victims through before swollowing them when there north and south met the star begins to be divoured loosing its stucture and anything less could just be a warning, this ones wierd
