Abstract:
A brief excursion into the history of magnetic measurements at the observatories of the IKIR FEB RAS, which begins with the International Geophysical Year (1957-1958) and subsequent decisions of the Government of the USSR and the Presidium of the Academy of Sciences of the USSR, adopted in 1960-1962, is presented. Achievements are considered: (1) successful monitoring of the magnetic field according to IAGA standards (registration of variations on a photographic tape, absolute observations, preparation of hourly values of the total field intesity components H,D,Z); (2) the transition in the early 2000s from analog to digital equipment, which ended with the certification of three observatories Magadan, Paratunka and Khabarovsk by the international INTERMAGNET network (variation measurements with a frequency of 1 Hz, absolute observations in manual mode, preparation of minute values of the magnetic field components); (3) reprocessing of archives of analog magnetograms and digital data available since the early 1990s. The analysis of the existing problems (personnel, financial, technogenic load, the need to modernize infrastructure and equipment) is made.
