Cosmic ray intensity for minimum phase of 24 solar cycle

In this paper, we study the cosmic ray intensity behavior over the declining phase of the solar cycle 24, with the ground based ATHN neutron monitor (NM). For this purpose, we have considered the three parameters solar flare index (SFI), sunspot number (SSN) and magnitude of the magnetic field vector B. During the declining phase of cycle 24 the results shows that the cosmic ray intensity has moderate anticorrelation with the parameters SFI, SSN and field vector B having correlation coefficient -0.44, -0.43 and -0.51 respectively. From 2014 to 2019 sunspot numbers are going to be decreased, the maximum sunspot number was found in April 2014. Further we analyzed the sunspot number variation with solar flare index and magnetic field vector magnitude B and found that the sunspot number was directly related with these parameters, the correlative results showed that the SSN have strong positive correlation with SFI and field vector B with coefficient 0.72 and 0.62 of these two. Conclusively the cosmic ray intensity variation is not responsible for the variation in the considered parameters but sunspot number cycle does effect on different solar and interplanetary conditions.
