A statistical analysis of the power spectra of the geomagnetic field components H and D for periods ranging between 3 min and 1 h was conducted at a lowlatitude observatory (L’Aquila, ̧"1.6) at the minimum and maximum of the solar cycle. For both components, during daytime intervals, we found evidence of power enhancements at frequencies predicted for global modes of the Earth’s magnetosphere and occasionally observed at auroral latitudes in the F-region drift velocities (approximately at 1.3… CONTINUE READING
