Sunspots are magnetic regions on the Sun with magnetic field strengths thousands of times stronger than the Earth's magnetic field. Sunspots usually come in groups with two sets of spots. One set will have positive or north magnetic field while the other set will have negative or south magnetic field. The field is strongest in the darker parts of the sunspots - the umbra. The field is weaker and more horizontal in the lighter part - the penumbra. Click on image for larger version.
Best Answer: Sunspots don't really do anything. They are magnetic storms on the Sun, cooler areas on the Sun's surface. They have absolutely no effect of the Earth's weather.Solar flares related to them do affect the visibility of aurora and, in extreme cases, interfere with telecommunications.unspots are actually the harbingers of magnetic activity on the Sun which can accelerate particles near the Sun to high energies, and eject them during flare events and Coronal Mass Ejections.
