Such links are provided consistent with the stated purpose of this DoD Web site. ``Space weather'' refers to the state of the magnetosphere and ionosphere which is determined by the solar wind. Under disturbed conditions, satellite- and ground-based technological systems, e.g., communications networks, electric power grids, and satellites, can suffer deleterious effects. Such systems are particularly vulnerable during severe geomagnetic storms . Large storms are relatively infrequent, but when they occur, they can stress the susceptible systems for prolonged periods of time over large geographic areas. Secure operation of systems can still be maintained and hazards can be minimized if the occurrence, duration, and severity of impending storms can be accurately predicted in a timely manner. Thus, space weather forecasting is important for protecting national assets in both the commercial and military sectors. This task is being carried out by the

103. Auroras: What Makes Them Happen?
     What makes aurora?  
     http://www.exploratorium.edu/learning_studio/auroras/happen.html
     
     Extractions: Before we can understand auroras, we need a few facts about the space around our Earth. There are many things in this space that we can't see. One thing is the air we breathe, our atmosphere. It is really a mixture of several gases, mostly nitrogen and oxygen, with traces of hydrogen, helium and various compounds. A Field of Earth Another thing we can't see is a magnetic field that surrounds the Earth. If you've ever played with a bar magnet and iron filings you've seen the curved patterns the filings form in the magnetic field. The next picture shows how the magnetic field around the earth's core is like the field of a bar magnet. The Earth's "magnet" is deep in the core. Since we can't see the magnetic field, we draw lines to represent it. The field lines go into and out of the Earth around the Earth's magnetic poles . Where the lines are closest together the field is strongest. Where they are furthest apart it is weakest. Can you tell where the magnetic field is the strongest? Where is it weakest?
