Abstract
Cosmic rays are high-energy particles originating from the stars in our galaxy and distant galaxies. These particles can infiltrate the Earth^s atmosphere and affect its magnetic field. Some previous studies showed that cosmic rays also influence aerosols and cloud formation. This study analyzes the relationship between solar flare activity and cosmic rays intensity. As mentioned earlier, we use the Pearson correlation coefficient to evaluate the correlation between the variables. We will use the solar flare data on C-, M-, and X-class flares and cosmic ray counts from 1996 to 2021, which coincides with the 23rd and 24th solar cycles. Our preliminary study showed that the number of X-class flares is highly anticorrelated to cosmic ray counts. In the meantime, we will also investigate the C- and M-class flares to better know the phenomenon^s details.
