Results of the ionospheric data processing (Paratunka station, Kamchatka) for 22–31 August 1987: a observed (black line) and median of the f o F2 time series (gray line), b detected anomalies for a threshold coefficient U of 2.3 and a moving time window length Φ of 336 h, c estimation of the anomaly intensity, and d K-indices above three (Paratunka station)
