Abstract
During the 1986-87 austral summer a geomagnetic observatory was installed at the Italian Antarctic Base
Mario Zucchelli Station (TNB, geographic coordinates:74.7S, 164.1E; corrected geomagnetic coordinates:
80.0S, 307.7E; magnetic local time MLT=UT-8). In the first years the measurements of the geomagnetic field
were carried out only during summer expeditions. Since 1991 the recording was implemented with an
automatic acquisition system operating through the year. More recently,after two short test surveys, from
October 2004 a geomagnetic French-Italian observatory was installed on the Antarctic plateau (Dome C,
DMC), very close to the geomagnetic pole (geographic coordinates: 75.1S, 123.4E; corrected geomagnetic
coordinates:88.8S, 55.6E; magnetic local time MLT=UT-1). In this work we present some results obtained
from TNB observations coming from almost twenty years of observations and also the preliminary results
obtained from the analysis of the first year of data from DMC.
