The magnetosphere is the interface between the interplanetary environment and the upper Earth's atmosphere. It is a vast region evolving under the control of the Earth's magnetic field. The magnetosphere is filled with a collision-free plasma, continuously out of thermodynamic equilibrium, turbulent, unstable, which undergoes almost daily global reconfigurations. The magnetosphere has only one visual manifestation, but of great aesthetic quality: the polar aurora.

Observational constraints on geomagnetic field changes from interannual to millenial periods are reviewed, and the current resolution of field models (covering archeological to satellite eras) is discussed. With the perspective of data assimilation, emphasis is put on uncertainties entaching Gauss coefficients, and on the statistical properties of ground-based records. These latter potentially call for leaving behind the notion of geomagnetic jerks. The accuracy at which we recover interannual changes also requires considering with caution the apparent periodicity seen in the secular acceleration from satellite data. I then address the interpretation of recorded magnetic fluctuations in terms of core dynamics, highlighting the need for models that allow (or pre-suppose) a magnetic energy orders of magnitudes larger than the kinetic energy at large length-scales, a target for future numerical simulations of the geodynamo. I finally recall the first attempts at implementing geomagnetic data assimilation algorithms.
