Sunspots are generated by strong and dense magnetic fields, and these magnetic fields are caused by flowing plasma that gets tangled and moves through the photosphere. [1] However, it is not actually sunspot activity that effects the Earth’s power grid and satellite communications, [2] but rather the solar flares and coronal mass ejections (CMEs) that can be caused by sunspots that cause problems. [3]
Solar flares are eruptions of energy from the sun’s surface. Quickly reaching temperatures of 10 to 20 million Kelvin, these flares can rise thousands of kilometres above the chromosphere, and can release energies of up to 6 x 1025 joules (equivalent to “the energy of a few million volcanic eruptions on the earth”) [4]. Solar flares have three classifications: X, M, and C-class. X-class solar flares are the largest of the three, and also have the largest impact on Earth, causing long-lasting radiation storms in the upper atmosphere, and causing radio blackouts. M-class solar flares are less powerful than X-class, however they can still cause the occasional radiation storm, and brief radio blackouts in the polar regions. C-class are the smallest of them, and barely have any impact on Earth. [5]

Solar flares give off large amounts of energy and radiation, and these are absorbed by the atmosphere in an attempt to reduce their effects on Earth. However, the increase of heat and energy result in the growth of Earth’s ionosphere. Because this is the section of the atmosphere in which man-made waves travel, radio communications can be disrupted by the unpredictable expansion. Satellites are also affected, because they go from travelling through a vacuum to travelling through the enlarged upper atmosphere. This leads to an increase in friction, a negative acceleration of the satellite, and the satellite returning to Earth sooner that intended.
The Aurora Australis is created by solar winds—continuously emitted stream of charged particles originating from the face of the sun. With periods of high solar activity, sunspots
The foremost differentiation between solar flares and coronal mass ejections (CMEs) is the scale on which they transpire. Solar flares are rather little and local, occuring in the low solar atmosphere, near sunspots, where magnetic field lines are concentrated. CMEs on the other hand are huge. They can even be bigger than the sun itself!
However, this has not happened and it’s starting to make secular scientist themselves admit that our sun is special and unique in design, because it does not emit these monster super flares like the ones produced by Proxima Centauri. The question is, could our sun send out such a flare powerful enough to even melt the ice on Jupiter’s moon’s, destroy earth’s ozone layer and even obliterate all our satellites? Well the answer is yes. Scientist have studied other sun like stars in our galaxy and discovered that they produce these super flares about once a century. But, they have no explanations as to why our sun does not produce such solar
Despite the amounts of incoming radiation, very little actually reaches the Earth’s surface. One layer of protection the Earth provides is in the form of a magnetic field that deflects charged particles from reaching the Earth’s surface. This magnetic field is generated by a combination of the liquids within the Earth’s core and the interplanetary magnetic field generated by the Sun. This field reaches out thousands of miles from Earth, so when solar wind travels through space and encounters Earth’s
Sunspots are dark spots on the Sun caused its magnetic field. The spots are dark because they are cooler than the area of the Sun that surrounds them and are often as big as the Earth.
Sunspots aren’t that complicated they’re really just dark spots on the sun’s surface. Now these sunspots have a strong magnetic field and always in motion. The sunspots take around 27 days or so to rotate, but we can only see, so much from the Earth’s surface, but for now 27 days would be our best answer. Now you probably haven’t heard about solar maximum or minimum, but they are also related to the topic of sunspots. They really just mean if their is no sunspots, solar minimum, and if their is the most we could possibly see, solar maximum, and both would be seen from earth, not space. Their is this thing where the sun envelops the Earth with energy, such as light and these elecrtically charged magnetic fields, or particles. This is what people call solar weather and after the earth is bathed with the forms of energy, their is only an effect that affects us durring an auroral event. If solar weather hits during an auroral event power grids may get
A hypnotizing video released by NASA yesterday shows stunning imagery of a plasma bursting from the Sun. The solar flare was so strong that it caused radio blackouts all across the earth. Did the space agency just stumble upon the gates of Heaven?
In 1945, Joseph Henry and Stephen Alexander, professors from Princeton University, discovered that sunspots emitted less radiation than surrounding areas of the sun. This is because the Sun’s outer shell, the photosphere, behaves as plasma, which is a very good conductor of electricity, and interacts with the magnetic fields of sunspots. The plasma slows down and cools to 1000 K less than the surrounding photosphere which makes it look darker than the surrounding areas. These areas were concentrated magnetic fields appear, are usually part of a loop, as sunspots generally present in pairs which line up parallel to the equator, showing a magnetic polarity. The sunspots in each hemisphere have the opposite polarity to the other. Over the 11 year cycle, the whole polarity reverses as the new set of sunspots form away from the Sun’s equator. Therefore, a complete 22 year cycle returns the polarity to its original
The great red spot on Jupiter has been going on for over 300 years. The winds on the red spot go as fast as 225 miles per hour counter clockwise. The great red spot is twice the size of Earth. The Great Red Spot sometimes grows but then shrinks. It is very unstable, actually, everything on Jupiter is unstable but this giant hurricane is the most unstable thing in the universe other than Sun. this storm has the power to tear apart all of the planets except Jupiter in our solar system even Saturn. This storm lets out a lot of magnetic energy when it collides with the other winds on Jupiter and radio
As the plasma rotates with the sun’s convection zone, consolidation of the magnetic flux tubes occurs such that their field strength is stronger. As the outer layers of the sun rotate faster near the equator than they do near the poles (“differential rotation”), as much as 1.3 times more than the rotation at 30° latitude (see figure 4, part 2, not to scale), the magnetic field becomes distorted forming lines of concentrated magnetic intensity (see figure 4, part 3). This activity causes enough turbulence to ‘buckle’ the magnetic field such that it bends out forming a loop above the photosphere, and as these regions rise through the solar atmosphere, the convective flow of energy is partially blocked, cooling the region and thus reducing its brightness, causing the darkness associated with sunspots (see figure 4, part
The number of sunspots on the surface and their size changes over time, in a cycle of approx. eleven years. Intense sunspot activity, which results in a high exchange of energy from the sun to the Earth, is associated with geomagnetic storms, which disrupt communications and power transmissions.
Solar flares, Sun spots, and Radiation are all vital parts of the sun cycle. Sunspots create solar flare which gives off radiation, without one another the sun could explode because of energy build up.
“All of them? I don’t know, but I would think so. What concerns me is the geomagnetic storms we’ve been having. The result of the solar wind gusts. We've got data from magnetometers—the elevated Kp Index. Jolts going off the charts. There's just no doubt any longer about a relationship between what we see happening on Earth and the solar wind. BUT then—you see—we also got solar wind coming from where our sun is most definitely NOT! You're the one who should be able to spot the source, Arnold. You're the whiz kid working with radiation emissions. Tell me what's going on here!”
The solar wind containing these hot gases races toward the edges of the solar system, and smash in to the magnetosphere. The magnetosphere protects the earth by deflecting most of the solar wind around the planet. Trillions of these charged particles mange to get through and project from the North and South poles. Energy released in this fashion excites atoms of nitrogen and oxygen, which in turn emit pulses of colored light. These formations are called an aurora. The aurora borealis, which are visible in Alaska, are a result of this sort of space storm.
Have you ever heard of a solar flare? A solar flare exists after a sunspot has existed for a long time and the magnetic lines of force usually become jumbled. As a result of this jumbling, magnetic energy is stored in the Corona (region of atmosphere above the chromosphere). The energy may be released in a spectacular discharge, which is a solar flare. A solar flare can be as wide as 367,000 miles and as high 500,000 miles out into space. A solar flare is nothing more than helium erupting from the sun like a volcano.
