“…The SFs are a sudden, intense, and rapid change in brightness of the sun in the corona above active regions, which occurs when magnetic energy is suddenly released into the sun's atmosphere. Effects associated with the occurrence of the SFs, in addition to the emission and acceleration of energy solar particles for example protons, electrons, also heavy nuclei, can lead to the generation of a strong radioactive storm that affects the space weather near Earth, which in turn damages to satellites, communications system or fiasco electric power (Inbua et al, 2019;Khumlumlert, 2017). SFs release energy to all lengths of the electromagnetic spectrum during their occurrence, which extends from a few seconds to several hours.…”

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

“…The SC was discovered by Samuel Heinrich Schwabe in 1843 who found that there are periodic changes in the average SSNs. The duration of the cycle is between 10-13 years and includes a change in solar activity, SSN, SF, and other space surroundings (Khumlumlert, 2017;Aiemsa-ad et al, 2015).…”
