An analysis of geomagnetic field variations (3 min-2 h) at a low-latitude observatory (L=1.6)

An analysis of the geomagnetic field variations between 3 min and 2 h at L'Aquila (<i>L</i>=1.6) shows that the power level in the low-frequency range (i.e. for periods longer than approximately 10 min) at solar maximum (1989/90) is much higher than at solar minimum (1985/86). C...
