Preliminary Measurements of Schumann’s Resonances (SR) in the Greek

Schumann’s Resonance (SR) measurements have been collected in the wider area of Ioannina by an equipment, designed and built in the laboratory of electronics and telecommunication of the University of Ioannina. Remarkable differences among measurements received in various epochs have been detected. At first, SR intensities taken around the Summer solstice are weaker than those taken around the Winter one, while SR intensities close to the Spring equinox are higher than those close to the Autumn equinox, on the average. Another obvious remark is a specific correlation between the SR intensity and the geomagnetic index Dst. Negative values of this index, which imply a disturb geomagnetic environment, correlate better with low SR intensity values. In the opposite, positive Dst values correspond to higher SR intensities. In general, the relative position of the Sun in relation to the earth as well as the solar/geomagnetic activity seems to affect the SR signals profile.
