Real time

Follow the geomagnetic development in real time! (NB! Absolute values are shown in the graphs. The data is not yet processed and may contain man-made signals. Real values in processed data (latest processed data 2022-10-31 23:59:59). Solar quiet curves shows the normal or quiet state for the magnetic field when not disturbed by solar storms. The development of quiet curves from 1978 can be seen here: Quiet curves 1978-).
