The outward flow of solar particles and magnetic fields from the sun. Typically, solar wind velocities are near 785,000 miles per hour or approximately 350 kilometers per second. The apparent void between Sun and Earth is actually a maelstrom of solar wind and storm, with interludes of calm, and always bathed in the harsh glow of ultraviolet and x-rays. Solar Sunspots Area seen as a dark spots on the surface of the sun. Sunspots are concentrations of the magnetic flows through the sun's surface.
Sunspots typically occur in clusters or groups.
They appear dark because they are cooler than the surrounding sun surface. In a matter of minutes, a large flare releases a million times more energy than the largest earthquakes. The Sun goes through cycles of high and low activity that repeats approximately every 11 years. The most recent solar maximum occurred in July 1989. The most recent solar minimum occurred in September 1986.
