Abstract :
Several solar activity phenomena occurring on the surface of the Sun, such as Sunspot number (SSN), Solar flare index (SFI), Solar flux (SF) etc. known as Solar activity. The Solar phenomena produced during 11- year cycle variation which is known as 11- year solar activity cycle. The Sunspot number (SSN), Solar flare index (SFI), grouped Solar flares (GSF) and Solar flux (SF) for the Solar cycle 21 to 24 have been analyzed. We have found that Sunspot number (SSN) and Solar flux (SF) are highly correlated in solar cycle 21 as compared to solar cycle 23. We have found that Sunspot number (SSN) and Solar flux are highly correlated in solar cycle 22 and are not highly correlated with solar cycle 24. Also we have found that Sunspot number (SSN) and (GSF) are highly correlated in Solar cycle 21 as compared to Solar cycle 22 and Solar cycle 23 and Solar flux (SF) are highly correlated in Solar cycle 21 as compared to Solar cycle 22 and Solar cycle 23. The maximum value of Sunspot number for Solar cycle 22 is greater than the maximum value of Sunspot number for Solar cycle 21, Solar cycle 23 and Solar cycle 24 and the maximum value of Grouped solar flare for Solar cycle 21 is greater than the maximum value of Solar flare for Solar cycle 22 and Solar cycle 23. The maximum value of solar flux for solar cycle 22 is greater than the maximum value of solar flux for solar cycle 21, 23 and 24

Key-Words / Index Term :
Sunspot number (SSN), Solar cycle (SC), Solar Flux (SF), Solar flare index (SFI) and Grouped Solar Flare (GSF)
