Dependence of the velocity changes of secular variations on the position of observatory and time
According to the data of world observatories net secular variations of geomagnetic fields from internal and outer sources have been studied. Averaged 3-year data have been used for this purpose.

Twenty years of geomagnetic field observations at Mario Zucchelli Station (Antarctica) [PDF]
During the 1986-87 austral summer a geomagnetic observatory was installed at Terra Nova Bay. During the first years both geomagnetic field time variation monitoring and absolute measurements were carried out only during summer.

Изменения геомагнитного поля Антарктики за последнее столетие
Определены особенности изменения геомагнитного поля в Антарктике в XX столетии по данным расчетов по модели IGRF (International Geomagnetic Reference Field) и наблюдений на обсерваториях. Получено, что в Южном полушарии полный вектор геомагнитного поля F

Why the sunspot cycle is double peaked [PDF]
Many sunspot cycles are double peaked. In 1967 Gnevyshev suggested that actually all cycles have two peaks generated by different physical mechanisms, but sometimes the gap between them is too short for the maxima to be distinguished in indices of the ...
