Modulation of Cosmic Ray Intensity along with Interplanetary Causes and Solar Activity Parameters during Solar Cycle 24
Abstract: Modulated of cosmic rays and their propagation in the heliosphere by the effect of the large-scale structure of the interplanetary medium. Its comparison of the variations of cosmic Neutron monitor intensity with variation of sunspot number, geomagnetic indices, solar wind velocity (V), interplanetary magnetic field (B), near the Earth for the period solar cycle 24 .it has been accessible as a likely correlation among them. we calculated the yearly average cosmic ray counts detected with Oulu NM. It is significantly undesirable correlation have been detected between interplanetary magnetic field (B), and cosmic ray intensity earlier the solar cycle 24. The sunspot number and solar wind velocity has a noble positive relationship with cosmic ray intensity during solar cycle 21, but it indications weak association before through solar cycle 24. The interplanetary magnetic field, B displays a weak negative association with cosmic rays for the solar cycle, while B shows a noble anti-correlation for the before during solar cycle 24 through cosmic ray intensity. The cosmic ray intensity displays decent positive correlation through interplanetary causes time, and geomagnetic indices (Dst) index forgoing the solar cycle 24 , whereas shows weak correlation for formerly the cycle 24.
