Biotropic geomagnetic pulsations Pc1 resulting from the magnetic storm of March 17, 2015

Resumo

Data obtained by a Hall sensor–based magnetic field detector have been used to record the spectral components of the geomagnetic field. An analysis of specific features of the spectral characteristics of geomagnetic fluctuations has indicated that the pulsations identified in the vicinity of the strong magnetic storm of March 17, 2015, are “pearl”-type fluctuations, i.e., biotropic geomagnetic Pc1 pulsations.
