Short summary
Remote sensing of the polar aurora and ionospheric convection is used to characterize the interaction between the solar wind and the Earth magnetosphere during steady magnetospheric convection (SMC) intervals and compare them with other previously studied geomagnetic conditions. It is found that the Earth magnetosphere may exhibit four different coupling modes ordered by increasing open magnetic flux and magnetic reconnection rate: quiet times, SMC, substorm and sawtooth events.
