Peculiarities of the Solar-Wind/Magnetosphere Coupling in the Era of Solar Grand Minimum

Based on the data of the solar wind (SW) measurements of the OMNI base for the period 1976-2019, the behavior of SW types as well as plasma and interplanetary magnetic field (IMF) parameters for 21-24 solar cycles (SCs) is studied. It is shown that with the beginning of the Era of Solar Grand Minimum (SC 23), the proportion of magnetic storms initiated by CIR increased. In addition, a change in the nature of SW interaction with the magnetosphere could occur due to a decrease in the density, temperature, and IMF of the solar wind.
