High Frequency Active Auroral Research Program (HAARP)
http://www.haarp.alaska.edu/cgi-bin/magnetometer/gak-mag.cgiThe High Frequency Active Auroral Research Program (HAARP) is an ionospheric research program jointly funded by the US Air Force, the US Navy, the University of Alaska and the Defense Advanced Research Projects Agency (DARPA).Geomagnetic storminess is usually indicated in oscillatory variations in the earth's magnetic field. Additional detail concerning the nature and severity of the ionospheric disturbance can be found through analysis of the three components of the field. Data from a chain of magnetometers are also available.

A magnetosphere is formed when a stream of charged particles, such as the solar wind, interacts with and is deflected by the intrinsic magnetic field of a planet or similar body. Earth is surrounded by a magnetosphere, as are the other planets with intrinsic magnetic fields: Mercury, Jupiter, Saturn…
The Kiruna magnetogram provides realtime data of the local Earth magnetic field at ground level. Strong deviations in the data, primarily the black line could signal the development of geomagnetic activity. The curves on this plot show deflections from an average. The average is derived from the monthly means of the five most quiet days.
