RUSSIAN JOURNAL OF EARTH SCIENCES, VOL. 19, ES1005, doi:10.2205/2019ES000650, 2019 ![]() Figure 1. Modelled path of the magnetic poles; yellow squares indicate observed locations, https://maps.ngdc.noaa.gov/viewers/historical_declination/. The gUFM model was used for 1590–1890, the IGRF model was used for 1900–2020, a smooth transition was imposed for 1890–1900 to connect the models. The modelled path often significantly deviates from the observed locations, and thus should be viewed only as a rough approximation of the real path. The 1859 turn in the path coincided with the Carrington solar storm of 1859/9/1-2; the 1730 turn in the path coincided with the Boston solar storm of 1730/10/22. The paths of both poles made significant turns in 1753–1755. Copyright 2019 by the Geophysical Center RAS. Generated from LaTeX source by ELXpaper, v.2.0 software package. |
