Statistical Analysis of the Monthly Activity of the Solar Flare

The study of solar flares (SF) is significant for a more understanding the nature and dynamics sun as well its impact on space weather. This paper will present new idea by studying monthly activity SFs collecting data SFs, flare index (FI), sunspots number (SSN) period from 1986 to 2019, which represents three cycles 22, 23 24. Extracting averages shows us that southern hemisphere active than northern hemisphere. Also, second half year first cycles. most months are March, (July or October) November, while February was least active. In addition, evidence cross-correlation results in strong positive relationship between variables. serves forecast state weather during year.
