About This Special Issue
General introduction: - On the basis of their origin Cosmic rays are classified as Galactic Cosmic Ray (GCR), Solar Cosmic Ray (SCR) and Anomalous Cosmic Ray (ACR). GCR originate far outside of our solar system and are the most energetic CR particles with energy extending up to 1021eV. SCR originate mostly from solar disc as well as flares. SCR particles have energies typically up to several hundred MeV/nucleon. ACR originates from the interstellar space beyond the heliopause. Short term decrease in cosmic ray intensity termed as Forbush Decrease (FD). Solar Flare is an explosion on the surface of the Sun that happens when energy stored in twisted magnetic fields (usually above Sunspot) is suddenly released. flares produced a burst of radiation across the electromagnetic spectrum, from radio waves to X-rays and Gamma rays. Daily variation is most significant type of variation in cosmic ray intensity which occurred due to extra terrestrial origin.

Aims and scope:- The solar flares around the sun and their association with Forbush decrease may be used to study the behavior of electromagnetic conditions prevailing over entire solar disc in better way. The cosmic ray modulation has added to our knowledge about the heliosphere. At present there is no definite theory relating the solar flare and Forbush decrease. However, a definite theory can be developed using various parameters over a long duration and performing comparative study between solar flare and Forbush decrease.
