Observing of polar cap dynamic by Greenland chain of magnetic stations

Observing technique of location high latitude zones of geomagnetic activity: polar cap, auroral oval and subauroral zone is demonstrated by the data from Greenland chain of magnetic observatories. Thebelonging of a particular observatory to the one of the indicated three zones is determined on the basis of self-training artificial neural network of Kohonen layer type. Amplitude-frequency specters of the geomagnetic data analysis during some quiet and disturbed days in 1998 serve as input data for calculation. To estimate the accuracy of our classification of zones of geomagnetic activity a special technique was designed – the results of classification were compared with a model of the boundary of the polar aurora oval, which is based on the analysis of satellite data from space crafts DMSP on distribution of particles. The correspondence of classification outcomes to this model is up to 60%. The outcomes of our research testify to the possibility of the using of the data from the Greenland chain of magnetic stations to control the temporary dynamics of location of the three areas of high latitude space in real time
