Abstract

In this paper we have studied a significant relation between Cosmic Ray Intensity (CRI) and Solar activity parameter. The study is extended to solar cycle 23-24. In the present work, yearly average of Sunspot number (SSN), Total solar irradiance (TSI) and magnetic field (B) have been used to correlate with yearly average cosmic ray intensity. Comparison has been drawn between the successive solar cycles and it has been noticed that for two solar cycles the cosmic ray intensity is anti correlated with sunspot number, Total solar irradiance and magnetic field. We find the correlation coefficient of cosmic ray intensity with sunspot number as well as Total solar irradiance which are relatively large and anti correlated during solar cycle 23-24. However the magnetic field shows a positive correlation with Total solar irradiance and sunspot number and correlation coefficient for sunspot number and Total solar irradiance is R= 0.80 for solar cycle 23-24. While as interplanetary magnetic field is significantly correlated with sunspot number and value of correlation coefficient is 0.61.
