A comparison between Pc5 geomagnetic field variations at different high latitude stations
Abstract
In this work we present a statistical analysis of geomagnetic field fluctuations in the Pc5 frequency band at Terra Nova Bay (Antarctica) and Cambridge Bay (Canada). The location of the two stations is particularly interesting in that they have exactly the same magnetic local time (MLT=UT-8hr) and almost opposite corrected geomagnetic latitude (-80.0^o and 77.4^o, respectively). The analysis is extended also to the stations Scott Base and Dumont D& acute; Urville (Antarctica), located at the same geomagnetic latitude as Terra Nova Bay but at different magnetic local time (MLT=UT-7hr and MLT=UT-13hr). In particular, the study is focused on the coherence between the signals observed at the different stations and on its local time and seasonal dependence.
