Abstract

Cosmic ray modulation is a complex process, which includes different physical phenomena in the solar-terrestrial space. At the Cosmophysical Observatory of Mikheil Nodia Institute of Geophysics a constant registration of the neutron component of cosmic rays has been conducted for decades. The article considers 5 cases of Forbush decrease revealed as a result of observing, processing and analyzing the data obtained in 2014-2018 at the observatory. The data of the above period were compared to the data of the stations in Moscow and Irkutsk, which according to the observation data proved the existence of Forbush effect. In our opinion during the above period certain solar flares really took place. Therefore, each separate Forbush effect requires scientific studies for further analysis.
