International Monitor for Auroral Geomagnetic Effects (IMAGE) consists of 41 magnetometer stations maintained by 8 institutes from Finland, Germany, Norway, Poland, Russia and Sweden.
The prime objective of IMAGE is to study auroral electrojets and moving two-dimensional current systems. The long profile covering geographic latitudes from 51 to 79 degrees is especially favourable for electrojet studies. Together with other ground-based recordings (by radars, riometers, all-sky cameras) and satellite observations, IMAGE is an essential part of the investigations of high-latitude magnetospheric-ionospheric physics.
Building from its predecessor, the EISCAT magnetometer cross that started in 1982, IMAGE also provides high-quality data useful for studies of geomagnetic induction and long-term geomagnetic activity in the auroral region.
