Abstract

A long term analysis of the power of geomagnetic variations in the micropulsations band at L'Aquila (Italy) revealed a weekly variation represented by an increased level of power in the working days with respect to Sundays. The maximum increase, by a factor of ~1.2, occurs during morning hours in the 100-500 Hz band. A daily-light-saving time effect has been also identified. Some implications on a wider scientific context are discussed.
