Sunspots are believed to be the sites where solar flares are generated. Sunspots are known to be "storms" on the sun's surface, but they are not yet fully understood.
add The surface of our Sun is about 5800 deg C and above, and naturally most of the material is highly ionized. Thus large electrical currents may be generated, and these in turn cause the magnetic field loops seen as solar activity. These magnetic loops can accelerate the charged ions from the Sun, hence the name Solar Flare..

How are sunspots related to prominence and solar flares?
The sun don't really need sunspots cause sunspots are related to several features on the sun's surface but prominences and solar flares need sunspots.Sunspots are the places where the magnetic field lines of the Sun poke out of the Sun to form loops.Where they poke out they are seens as prominences against the edge of the Sun's visible disk during an eclipse of the Sun.The looped magnetic field lines contain energy and are unstable, When they break and reconnect they release this energy suddenly and cause solar flares.
Do solar flares from the sun cause auroras near earths poles?
Magnetic storms unleashed by solar flares can cause auroras, but all solar flares don't cause auroras.
What can cause auroras near earth poles?
Solar winds are the out-of-this-world event that cause auroras to appear on earth. Auroras can happen near both the north and the south poles.
What causes solar flares prominences and sunspots?
Although the cause of flares is not completely understood, they are known to be associated with the magnetic field of the Sun. One favored explanation is that they occur when magnetic fields in the Sun pointing in opposite directions interact strongly with each other. Such a situation can be brought about by the churning motion of solar material near the surface, and is more likely during periods of the active sun. Thus, there typically is a correlation between the frequency of flares and the number of sunspots.
Where do solar eclipses happen the most?
near the equator
What are small bursts of fire near sunspots called?
Small bursts of fire near sunspots are called solar flares. Solar flares eject clouds of electrons, ions, and atoms through the corona of the sun into space. These ejections reach the earth a day or two later.

What are bursts of solar energy that occur over or near a sunspot?
Solar flares are brief outbursts that appear as a bright region above a sunspot cluster. Solar flares emit enormous quantities of energy in the form of ultraviolet, radio, and X-ray radiation.
What do solar radiation consist of?
Solar flares mainly consist of helium and hydrogen ... these two gases are the energy suppliers in solar flares .... when solar flares fall on the surface of the earth then due to friction the atomic bond becomes unstable and the gases FUSE and explosion occurs.. usually solar flares have 10 raise to the power 32 ergs of energy ..
What will happen on November 3?
a solar eclipse will happen near Africa
Where do solar eclipses happen the most?
near the equator
What are solar winds and how do they affect your solar system?
TA solar flare is a large explosion in the Sun's atmosphere that can release as much as 6 × 1025 joules of energy[1] (about a sixth of the total energy output of the Sun each second). The term is also used to refer to similar phenomena in other stars, where the term stellar flare applies.Solar flares affect all layers of the solar atmosphere (photosphere, chromosphere, and corona), heating plasma to tens of millions of kelvins and accelerating electrons, protons, and heavier ions to near the speed of light. They produce radiation across the electromagnetic spectrum at all wavelengths, from radio waves to gamma rays. Most flares occur in active regions around sunspots, where intense magnetic fields penetrate the photosphere to link the corona to the solar interior. Flares are powered by the sudden (timescales of minutes to tens of minutes) release of magnetic energy stored in the corona. If a solar flare is exceptionally powerful, it can cause coronal mass ejections.X-rays and UV radiation emitted by solar flares can affect Earth's ionosphere and disrupt long-range radio communications. Direct radio emission at decimetric wavelengths may disturb operation of radars and other devices operating at these frequencies.Solar flares were first observed on the Sun by Richard Christopher Carrington and independently by Richard Hodgson in 1859 as localized visible brightenings of small areas within a sunspot group. Stellar flares have also been observed on a variety of other stars.The frequency of occurrence of solar flares varies, from several per day when the Sun is particularly "active" to less than one each week when the Sun is "quiet". Large flares are less frequent than smaller ones. Solar activity varies with an 11-year cycle (the solar cycle). At the peak of the cycle there are typically more sunspots on the Sun, and hence more solar flares.
What are the features found on the surface of the sun?
The most discernable features on the Sun are sunspots; areas that are a little cooler, and therefore a little darker, than the rest of the Sun around them. We know that sunspots are formed by intense magnetic regions, and that large solar flares and prominences are associated with sunspots. There's a cycle of increasing and decreasing numbers of sunspots that runs about 11 years in length, although this can vary by a couple of years. Slower cycles seem to be correlated with fewer sunspots, and faster cycles with more sunspots, but scientists don't have a detailed explanation for why the cycle exists, or why it is 11 years (more or less) in length. We are currently (in 2014) at or near the maximum of the sunspot cycle. You can see the daily view of the Sun and yesterday's sunspot number at the SpaceWeather website, www.spaceweather.com.
