Abstract: Cosmic rays are high energy charged particles. The modulation of cosmic rays intensity (CRI) is related to solar activity. Sunspot number (SSN) are the signature of solar activity. We have done analysis to find the relationship of Cosmic ray intensity with solar activity for solar cycle23 and the ascending face of 24 solar cycle. The correlation coefficient (r) between CRI and SSN are found high and negative (r=-0.78) which varies randomly from one year to another Equally importance, X-rays and UV radiation emitted by solar flares. The frequency of solar flares is directly related to sunspot numbers. Thus the present analysis will help to correlate X Rays classification with cosmic ray intensity and solar activity.
Keywords: Cosmic ray modulation, SSN, Solar activity, X-ray classification, Solar flares
