Yearbook magnetic results 2015 Geomagnetic observatory of Castello Tesino

Abstract

Castello Tesino observatory is one of the three geomagnetic observatories in Italy operated and maintained by the Istituto Nazionale di Geofisica e Vulcanologia. The observatory is located near the homonymous town, 55 km East from the city of Trento (Northern Italy). The observatory co-ordinates are: Geographic latitude Geographic longitude Corrected geom. latitude Corrected geom. longitude Height above mean sea level Magnetic local time midnight 46° 03 N 11° 39 E 40° 47 N 86° 23 E 1175 m 22:31 UT The corrected geomagnetic co-ordinates and the magnetic local time midnight in UT are computed using a routine available at http://modelweb.gsfc.nasa.gov and assuming the North geomagnetic pole at 82°20 N, 276°38 E. Castello Tesino Observatory has been working almost continuously since 1964 and it is considered the main Northern Italy magnetic observatory. Data from this observatory are used to study the temporal trend of the geomagnetic field in Northern Italy and to reduce magnetic field data obtained during magnetic surveys to the same period (http://roma2.rm.ingv.it/it/risorse/rete_magnetica_italiana/36/cartografia_magnetica_nazionale). The staff that collaborates to the maintenance of the observatory and in the production of Castello Tesino data set and yearbooks is: Benedetti G. absolute measurements, plots and instrument maintenance; Biasini F. absolute measurements and observatory buildings maintenance; Di Ponzio A. data processing; Fattore F. absolute measurements; Miconi M. absolute measurements; Spadoni S. data processing, data storage and data base services; Zirizzotti A. instrument maintenance This yearbook presents the results of the magnetic measurements carried out at this observatory during 2015.
