VARIATIONS ^*: 22/Dec/2024

^*The graphs correspond to minute mean values. INTERMAGNET distinguishes at least three progressive types of data: Variations are provisional data corrected by approximated constant baselines; Quasi-definitive data have been revised and corrected by means of preliminary baselines (they may still be subject to small changes); Definitive data have been reviewed and properly corrected by means of definitive baselines. Data of the most definitive type available depending on the selected day are depicted in each case.
