Results of processing of the data of geomagnetic field and cosmic rays for the period 4 to 6 September 2012. Athens station: (A) cosmic ray time series, (B) smoothed component of cosmic ray time series (black) and its approximation by neuron network, (C) neuron network error, (D) H-component of the magnetic field of the Earth at Nea-Makri station (Greece), (E) assessment of geomagnetic disturbance intensity, (F) allocation of the periods of weak and strong geomagnetic disturbances, (G) allocation of the periods of strong geomagnetic disturbances, and (H) solar wind speed.
