AA* indices of values greater than 60 10-9 Tesla are considered in order to characterize geomagnetic storms since the available series of these indices comprise the years from 1868 to 1998 (the longest existing interval of geomagnetic activity). By ap...

The thinning of the stratosphere ozone layer in the Antarctic region is studied by considering ground-based observations at Belgrano Station (78.0ºS; 38.8ºW). Gumbel's first distribution of extreme values is used to evaluate the highest depletion of t...

Auroral observations of equatorward extent of the rayed auroral displays are researched. Ground-based observations at Belgrano Station (78.0º S; 38.8º W) during the southern winter months of 1981 are considered. Four hourly sequences of geomagnetic in...

Our research was based on different kinds of auroral observatons at Belgrano Station (78.0°s, 38.8°w). we have studied 145 dark days, from March to September, 1971. We have obtained about 45% nights without identified auroral displays, because periods wi...
