On June 21, 2023, the first MARGE station was installed in Montegiove, Umbria region (42°55'51.95" N, 12° 9'11.60" E). We used “search-coil” magnetometers and buried electrodes for the estimate of the ambient electric field (see the typical site configuration here), for a “high-frequency short-term campaign”. After 11 days, on July 3, 2023, instruments were removed and the acquisition campaign was concluded. Please visit the Multimedia page of this site for more information.
