| Abstract: | We studied the Forbush decreases of cosmic rays intensity during the Solar Cycle 24 using the Moscow Neutron Monitor. Forbush decreases (FDs) are sudden, short-term reductions in cosmic ray intensity observed on Earth, commonly triggered by solar events such as Coronal Mass Ejections (CMEs), solar flare (SFs) and Interplanetary Magnetic Fields (IMFs). We will explore the effects of major causes of Forbush decreases such as solar coronal mass injection, solar flares and Interplanetary Magnetic Field (IMF) to understand how the Fds in cosmic ray intensity are caused by them. This paper explores the effect of solar CME, SF and IMF on Forbush decreases as well as their interaction and investigates the underlying mechanisms responsible for the modulation of cosmic ray intensity during these events.In this study report, we have gathered a total of 56 Forbush decreases of magnitude ≥3% from the Moscow Neutron Monitor during Solar Cycle 24. This study uses observational data from Moscow neutron monitors, Omniweb, National Oceanic and Atmospheric Administration (NOAA) and the Solar and Heliospheric Observatory (SOHO) to examine how the IMF, solar flares, and CMEs impact FDs during SC 24. 94% of Fds are linked to solar flares, and the majorities are linked to halo CME and partial halo CME, according to our observations. The magnitude of Fds and the speed of CME were shown to be positively correlated, with a coefficient of 0.28. Also, all the Forbush decreases are associated with IMF. We observe a positive correlation between the magnitude of Fds and the peak value of IMF, with a correlation coefficient of 0.24. We found a positive correlation between the magnitude of Fds and the magnitude of IMF, with a correlation coefficient of 0.25. We concluded that the CME associated with IMF and SF are responsible for the Forbush decreases. |
