Processing results of the geomagnetic and ionospheric data for 29 September–5 October 2013: a H-component of the Earth’s magnetic field, b assessment of the geomagnetic disturbance intensities, c identification of the periods of weak and strong geomagnetic disturbances, d identification of the periods of strong geomagnetic disturbances, e solar wind speed, f observed f _o F2, g absolute smoothed component model errors, h absolute detailing component model errors, i estimation of the anomaly intensity, and j detected anomalies for a threshold coefficient U of 2.5 and a moving time window length Φ of 336 h. Graphs g and h show the standard deviations of the component model errors (dashed lines)
