Abstract :
Theoretically, Forbush effect is highly connected to solar activity. Persistent presence of solar wind, magnetic storms and any types of solar flares with or without coronal mass ejections cause the occurrence of Forbush effect as cosmic ray’s flux. In this work by using some data from OMNIWEB and Izmiran observatory, we explore the relation between Forbush effect, solar wind and local parameters during one of the most massive coronal mass ejections of the century and define a new quantity which is in strong correlation with Forbush effect magnitude.
