ABSTRACT

The article provides information about the Yangibazar geomagnetic observatory, managed by the Institute of Seismology of the Academy of Sciences of the Republic of Uzbekistan. The results of the study of magnetic field variations at the Yangibazar magnetic-ionospheric observatory and comparison of the average annual values of the magnetic field absolute magnitude with the main magnetic field of the Earth are demonstrated. A comparison is made between the diurnal variation of the geomagnetic field for four days on June 21–24, 2021 at the Yangibazar observatory and the diurnal variation for the same period at the nearby stations and observatories Alma-Ata (Kazakhstan) and Gyulagarak (Armenia), the absolute values of the magnetic field elements recorded at the observatory in the period 2010–2021 were also studied. The conclusion is made about the expediency of deploying high-precision geomagnetic measurements that meet the international standard on the basis of the Yangibazar observatory.
