Sunspots and Sun Storms - Essay ExampleSunspots occur in groups and appear and disappear at certain(p) times. The sun could have hundreds of them sometimes and at other times only have a few. A sunspot potentiometer last between one and a hundred days. When they appear as a group, the sunspots can last approximately 50 days. Comp ard to the average surface temperature of the sun 6000 Celsius, the sunspots be about 1500 Celsius and can last from a few hours to a few months. In diameter, the sunspots can be as gigantic as 80,000 km and as they move across the suns surface, they expand and contract. They can be explained as regions on the sun with strong magnetic field strengths that appear often in pairs that are aligned in an east to west direction and are thousands of times stronger if compared to the magnetic field of Earth. This implies that the locomote magnetic tubes flux that breaks past the suns surface form the sunspots. In a dissembling of the initial condition shows tha t there is a horizontal uniform layer of the magnetic field, in a stably stratified fluid, that is subject to a small perturbation.One of the factors that cause sunspots is intense magnetic field such that sunspots occur in pairs and the magnetic field comes from one and enters into another one. The magnetic fields that are inside the sunspots are 1000 times stronger compared to those surrounding the undisturbed areas.The magnetic layer is unstable callable to its buoyant nature, so out of its layers, the magnetic flux can rise. The center of a sunspot, mainly the minatory spot is called the umbra the magnetic fields are highest in this area. The striated area around the umbra, which is less dark, is called the penumbra. As seen from earth, it takes the sunspots 27 days to make a complete rotation, since they rotate with the solar surface. Near the Suns, equator sunspots rotate at a faster rate than those near the solar poles.
