Description
In the context of the study of the conditions of the Earth's magnetosphere and space weather, we present the magnetometer installed at the INAF-Turin Astrophysical Observatory (Italy), included in the SWELTO (Space Weather Laboratory of Turin) project. A fluxgate magnetometer, after testing and calibration, has been positioned in the Turin Observatory (45°02'27"N, 7°45'48"E), and in November 2024 started to acquire data which can be viewed in quasi realtime on the SWELTO portal (https://swelto.oato.inaf.it/geomag_oato.html). The acquired data, in the form of voltage measurements, are converted and then calibrated by subtracting the quiet reference curve based on the quietest days of the month preceding the one being analyzed. This allows for an accurate identification and analysis of major geomagnetic disturbances. The instrument provides not only the three components of the Earth Magnetic Field, but also the local value of the so-called "Dst-index", that is compared to the global "Dst-index" provided by the World Data Center for Geomagnetism - Kyoto, finding a very good agreement for all the observed events. Here we summarize the calibration and the analysis of almost two years of magnetometer data (from end of 2024 to mid 2026), with a focus on known events that occurred during this period of Solar Maximum.
