Something big is happening on the sun. The sun's global magnetic field is about to flip, a sign that Solar Max has arrived.

How come I haven't heard of this before? I mean this sounds pretty important. Also does this happen to all stars? and does it happen to planets such as our own? Imagine if every 10000 years on earth we had to change where the signs are on our compasses haha

VERY CONFUSED-she sometimes says the field reverses at maximum, and sometimes that it occurs at the minimum (producing pairs of whole cycles in alternate polarity)...

Scientists predicted that this year sun activity will be increased greatly. Michio Kaku said that people better be ready by improving their power boxes and electricity controlling stations. Quite a few of those boxes will blow up this year. And a lot of people will lose electricity until things are repaired from that EM blast from sun.

If you don't know this solar cycle is lackluster so far, last cycle featured 4 flares above X10 (2 of them created days worth news in main stream media... as thye happened in one day), but record of this cycle is X6.9 which happened in 2011 and only top 6 flares so far crossed X2. Number of sunspots is more then a half smaller then last cycle. Some people believe we might approaching another Maunder Minimum which been observed in 17 and 18 cencury

We have a lot of people with less than a 6th grade scientific literacy, and when one understands science the whole world opens up like a lotus flower blooming. I have no idea what the world must seem like to them but I can imagine it must be scary and many escape through drugs. The people who generate fake controversy are mostly religious, they also have a dark age view of the world and live in perpetual doomsday fear.

No, the trajectory of the comet ISON will not be affected by this. Magnetic fields have only an effect on charged particles and comets are made out of neutral particles. So the comet's trajectory won't be changed. Maybe the size and/or brightness of the comet's tail might be slightly affected by a change in solar wind intensity/velocity, although I don't really know that.

that's an excellent question, in my book the old cycle # 24 finished on the 17th may 2013, cycle #25 starts on the 28th july 2014 with a reverse polarity, the sun is now at solar minimum and the planets around the solar system should show signs of cooling, keep your eye on the north west passage, it's earth's canary in the coal mine for climate.

My understanding is Yes they will flip. North will become South and South will be North. It happens on a regular basis. I am not positive but I think it is something like every 3 - 400,000 years or so. Please correct me if I'm way off the mark.

1.044291492 10+26 Volts is Sun electrostatic potential.And out of these constants can be calculated precisely radius of electrons: re = 2.820947793 10-15 m area = 9.999999116 m² D = 5.641895587 10-15 m O = 1.772453773 10-14 m fres. = 1.691397895 Hz Which means that the Coulomb constant look like this: re/8.979355709 * 10 +9 = π 10-10 1e = 0.01044291492 / (8.987551787 * 10-16) = 1.161930885 10-19

@TheMatrixDNA
@TheMatrixDNA 11 лет назад
Theoretical models by Matrix/DNA Theory suggests a different explanation for this flip. This magnetic pole shift happen in the Sun by the same mechanism discovered by physicist and Nobel Prize winner Hideki Ywkawa which produces proton changes into a neutron and vice versa, in the atomic nucleus. Each magnetic field has a conical shape and the two are coupled in the region of the solar core. The reversal of the poles is an evolutionary process from the atomic nuclear reversal between protons and

Yes, Phil. You're spot on friend. Wallace Thornhill and Don Scott have more comprehension of how the solar system and the Cosmos work than any two fellas on the planet. They would of course have chuckled, as I'm sure you did, at the newbie errors in logic that riddle this and other NASA science-as-newscast videos. But at least they are able to bring themselves now to use that verbotten "E" word : ELECTRICITY, even if they do have the entire thing backwards. This is clear progress

@sssdeecee
@sssdeecee 11 лет назад
Sorry... I just realized that I improperly worded my previous reply. Increased solar activity (and resulting auroras) are NOT likely caused by the magnetic field reversal. The reversal simply signals the peak of activity which is during a time of maximum solar activity.
@ShadowriverUB
@ShadowriverUB 11 лет назад
You don't get it :p what they observed since 1976 fit to solar cycle which been observed based on sunspot activity half of 18 century and even earlier but back then there was Maunder Minimum that disturbed solar cycles processes on sun. If it fits to solar cycles and those solar cycles been repeated for so many times it easy to assume it happens with each solar cycle.Not to mention sunspot/active region polarization also is flipped every cycle but on minimum not maximum,been observed earlier too
@rdmajumdar
@rdmajumdar 11 лет назад
Did anyone else notice the gradual decay in the maximum absolute amplitude of the polar field in that Solar Polar Field Strength vs time plot? The first negative maxima is higher than the second positive maxima which is higher than the second negative maxima. What's up with that?

It fits to solar cycles which was observed 23 times (+1 we currently in), polar flip might even cause of cycle as main reason of sunspot showing up is magnetic fields going crazy.

magnetic flip obviously means, that electrons within the suns magnetosphere will change their direction, Same as on the earth, the Northern Pole is currently the + or "gravity" pole attrackting solar electrons (measurable esp. after SEP events, The Southern pole contains more energetic electrons (-) attrackting solar protons. My theory: The Sun`s Center of gravity is NOT located right in its middle. and shifts all 11y to the South/ North, Then electrons will also change their direction

My recent visit to my doctor who is a Dermatologist was alarming. She warned me not to not have my skin come into direct contact with Sunlight? I chuckled, and took her warning lightly, then she got furious. She told me that her warning wasn't meant to be humorous. Why, asked. The incidences of skin cancer has soared and she didn't want me to be her next case! Wear a hat, sunglasses, long sleeved shirts, long pants and wear sunblock. Our atmosphere has changed sunlight is now dangerous?
