A major trend in the solar magnetic field that began at the end of solar cycle 22 continues to be observed. The main characteristics of the solar magnetic field and the associated heliospheric field are crucial to the modulation of cosmic rays. Long-

For the first time, based on the experimental data of AMS-02, a three-parameter spectrum of variations of ga - lactic cosmic rays was obtained in the range of rigidity 1- 20 GV, to which neutron monitors are most sensitive. It was found that during t

The irregularity of the solar activities based on sunspot numbers (SSNs) and areas (SSAs) over the solar disk has been considered. More activities phenomena occurred in one of the solar hemispheres than the other at the same time, which they are refe
