Sun will 'flip upside down' within weeks, says Nasa

[Sunny-side-up]

Turned on the computer and first item I see is this Independent News Paper item.
So have a Sunny-one-on-me:o

The Sun is set to “flip upside down” within weeks as its magnetic field reverses polarity in an event that will send ripple effects throughout the solar system.

Although it may sound like a catastrophic occurrence, there’s no need to run for cover. The sun switches its polarity, flipping its magnetic north and south, once every eleven years through an internal mechanism about which little is understood.

The swap could however cause intergalactic weather fronts such as geomagnetic storms, which can interfere with satellites and cause radio blackouts.

what happen if the Sun flip? what impact or effect does it have on Planet Earth?

Hmmmm might this be the reason (or excuse) for recent "concerns" about the grid going out (legit or contrived)?

[Cognitive Dissident]

Very interesting. But if it is an 11 year cycle, we would've known about this for a while. I thought the mechanism was so unclear in couldn't be predicted to within a few weeks?

Anyway, for sure the Sun should have a lot more attention.

Ison, I think is hype, but will keep an open mind.

We now all to well here in Avalon that even innocent and maybe insignificant phenomenon, like Ison needs an Awake-Eye on it or TPW will try to use it for their dirty little game if the timing suites them!
Look for a probable and be there first is the game nowadays.

Hello Sunny-side-up.....here's a video i came across recently that's got some interesting info. in it so thought i'd share :)

(An 'electrical sheet' that flows out from the Sun's equator which is better at repelling incoming cosmic rays during a magnetic reversal ? I don't know why but i would have thought it was the other way around ! Oh how i wish i was cleverer :p )

Atleast the sunny side will still be up... sorry couldnt resist ;)

The solar cycle is imperfectly interlocked with Jupiter's orbital period of 11.86 years, so there is no precise dating to work to.

Eleven years is a long time when you have have the mainstream media behaving as if we were all born yesterday. Talking of yesterday, there was an item on the primetime evening news to watch out, I kid you not, for one or two snowflakes, something that can't have happened as early as late November for what, at least two or three years.

Solar cycle


The solar cycle was discovered in 1843 by Samuel Heinrich Schwabe, who after 17 years of observations noticed a periodic variation in the average number of sunspots seen from year to year on the solar disk. Rudolf Wolf compiled and studied these and other observations, reconstructing the cycle back to 1745, eventually pushing these reconstructions to the earliest observations of sunspots by Galileo and contemporaries in the early seventeenth century. Starting with Wolf, solar astronomers have found it useful to define a standard sunspot number index, which continues to be used today.
Until recently it was thought that there were 28 cycles in the 309 years between 1699 and 2008, giving an average length of 11.04 years, but recent research has showed that the longest of these (1784–1799) seems actually to have been two cycles,[1][2] so that the average length is only around 10.66 years. Cycles as short as 9 years and as long as 14 years have been observed, and in the double cycle of 1784-1799 one of the two component cycles had to be less than 8 years in length. Significant variations in amplitude also occur. Solar maximum and solar minimum refer respectively to epochs of maximum and minimum sunspot counts. Individual sunspot cycles are partitioned from one minimum to the next.
Following the numbering scheme established by Wolf, the 1755–1766 cycle is traditionally numbered "1". The period between 1645 and 1715, a time during which very few sunspots were observed, is a real feature, as opposed to an artifact due to missing data.[3] This epoch is now known as the Maunder minimum, after Edward Walter Maunder, who extensively researched this peculiar event, first noted by Gustav Spörer. In the second half of the nineteenth century it was also noted (independently) by Richard Carrington and by Spörer that as the cycle progresses, sunspots appear first at mid-latitudes, and then closer and closer to the equator until solar minimum is reached. This pattern is best visualized in the form of the so-called butterfly diagram, first constructed by the husband-wife team of E. Walter and Annie Maunder in the early twentieth century (see graph below). Images of the Sun are divided into latitudinal strips, and the monthly-averaged fractional surface of sunspots calculated. This is plotted vertically as a color-coded bar, and the process is repeated month after month to produce this time-latitude diagram.

The physical basis of the solar cycle was elucidated in the early twentieth century by George Ellery Hale and collaborators, who in 1908 showed that sunspots were strongly magnetized (this was the first detection of magnetic fields outside the Earth), and in 1919 went on to show that the magnetic polarity of sunspot pairs:
Is always the same in a given solar hemisphere throughout a given sunspot cycle;
Is opposite across hemispheres throughout a cycle;
Reverses itself in both hemispheres from one sunspot cycle to the next.
Hale's observations revealed that the solar cycle is a magnetic cycle with an average duration of 22 years. However, because very nearly all manifestations of the solar cycle are insensitive to magnetic polarity, it remains common usage to speak of the "11-year solar cycle".
Half a century later, the father-and-son team of Harold Babcock and Horace Babcock showed that the solar surface is magnetized even outside of sunspots; that this weaker magnetic field is to first order a dipole; and that this dipole also undergoes polarity reversals with the same period as the sunspot cycle (see graph below). These various observations established that the solar cycle is a spatiotemporal magnetic process unfolding over the Sun as a whole.



So it's actually 22 year magnetic cycle ..



Did they forget to evolve major conspiracy theory about it this year ?

So it's actually 22 year magnetic cycle ..

Yes, approximately. But when looking at the solar cycles in any graphical form it's obvious the 11/22 year cycles are quite variable.

The 20th century solar cycle average has been about 10.5 years, so I suspect Jupiter's orbital period of 11.86 years, although an interesting coincidence, is probably a red herring!
