Title: Long period geomagnetic field fluctuations at Terra Nova Bay (Antarctica)
Authors: Villante, U.*
Lepidi, S.*
Francia, P.*
Meloni, A.*
Palangio, P.*
Keywords: magnetic pulsations
Antarctica
Issue Date: 15-Jun-1997
Publisher: AGU
Title of journal: Geophysical Research Letters
Series/Report no.: 12 / 24 (1997)
Abstract: A statistical analysis of the power spectra (0.7 - 5 mHz) of the geomagnetic field components H and D recorded at Terra Nova Bay (Antarctica) during three austral summers close to the maximum of solar activity reveals power enhancements in the H componenta t = 3.3, 3.9 and 4.5 mHz, which become more evident during daytime intervals. During intervals characterized by higher solar wind speeds these spectral features more clearly emerge and are also accompanied by other enhancements at lower frequencies (= 1.2, 1.9 and 2.7 mHz). The observed frequencies are close to the ones detected both at auroral and low latitudes.
