These animations show the height-integrated Pedersen conductivity as intensities of yellow color. The red polyline over Scandinavia is the IMAGE magnetometer chain. The coordinates are magnetic dipole coordinates. The data has been gathered from the GUMICS ("Grand Unified Magnetosphere-Ionosphere Coupling Simulation") code. In the run we may see two auroral breakups with preceeding auroral fadings, as well as a double oval situation between the breakups. The model is fully self-consistent in the sense that no observational data input is required. PJ 2.12.1994
