Statistical Analysis Of Outbreak Of Solar Activity In Cycle 23 And 24

Sun sunspots are the most basic and most common solar activity,and the earliest research and understanding of solar activity is based on the understanding of sunspots,while the sun sunspots for a long time sequence for people to understand the cycle of solar activity and other characteristics of the support.Before 2015, people have been using the number of sunspots published in the world to carry out the solar activity cycle and the long-term prediction of solar activity, as well as solar activity during the various solar activity phenomenon research, however, in 2015, people sunspots The number of long time series has been amended, and now the number of sunspots published in the international sunny monthly average is also revised after the data. Therefore, due to changes in the number of sunspots, according to the original sun sunspots to carry out the relevant research need to re-carry out the relevant research. In this paper, we first analyze the changes of the monthly mean number of solar sunspots before and after the 23-24 solar activity. The correlation coefficient between F10.7, flare integral flow and sunspot number and sunspot area is calculated. The Gnevyshev Peak and Gnevyshev Gap characteristics of the sunspot mean monthly mean and the monthly mean of the solar flare flow were compared between the 23 rd and 24th solar activity cycles. The asymmetry of north - south distribution of different solar parameters is analyzed. Secondly,we study the distribution of solar proton events with the solar meridian and the solar week. Finally, the relationship between solar proton event and flare integral flow is discussed.
