Abstract : Research on the distance-variability of the magnetic field components within the auroral zone was conducted with a Briunelli magnetic variation recorder at Nagurskaya Bay (Franz Josef Land). The magnetic field variation was recorded on film, continuously from the 13th of April to the 6th of May and was compared with the magnetograms of the Tikhaya Bay magnetic observatory, a distance of 108 km from Nagurskaya. For a quantitative comparison of the mobile recorder traces and the magnetograms of the constantly operating observatory, momentary values of the departures of H and Z from the quiet field were used at moments when the field assumed characteristic extreme (maximum or minimum) values. These extremes were taken in sequence, just as they occurred in the mobile recorder data, and practically all of them coincided in time with the extremes at Tikhaya Bay. From the corresponding pairs of departures from the quiet field values the calculated correlation coefficients are given in tabular form. The able also shows the ratios of the correlation coefficients to the dispersion; these ratios are an indication of the reliability of the computed correlation coefficients.
