چکیده

This paper discusses the estimation of zonal geomagnetic indices two super activities 2015 in 24th solar cycle. It estimates (Dst, ap, AE) 17 March and 22 June storms with an artificial neural network model . The that happened are considered on wind parameters (B z , E, P, N, v, T) obtained from NASA coordinated data analysis web. Descriptive values variables indicated, binary correlations shown covariance matrix hierarchical cluster presented by dendrogram. In paper, physical principles govern model. utilizes as inputs outputs causality principle shapes models cause-effect relationship. Back propagation algorithm is specified Levenberg–Marquardt (trainlm) 30 numbers used network. Dst, AE reliable accuracy. activity can support interplanetary studies.
