Beschreibung:
Some anomalies in geomagnetic variations observed in Italy from 1957 on, are referred about. The main phenomenon, observed at Ponza Island (Central-Southern Italy), is characterized by an almost absolute parallelism between ΔZ and ΔH variations, during disturbances shorter than two hours. In its larger evidence, this phenomenon is limited at Ponza Island and it attenuates rapidly when approaching the opposite Italian coast: it vanishes almost completely at L'Aquila Observatory (Central Italy) and Mt. Capellino (Genoa). Instead, an effect of antiparallelism was observed at Frontone (North Italy) while operating a temporary station installed there in the occasion of the Solar Eclipse of February 1961. A further investigation has been performed recently on Sq variations. © 1964, Society of Geomagnetism and Earth, Planetary and Space Sciences. All rights reserved.
