Statistical Analysis of Sunspot Area and Magnetic Flux on Solar Disc During 2011 – 2023

We investigate the temporal variations and distribution functions of daily sunspot area and magnetic flux data from 2011 to 2023. The yearly distribution of sunspot area on the solar full disc, southern hemisphere and northern hemisphere, and magnetic flux on the solar full disc are positively skewed for all the years from 2011 to 2023. We analyzed the variations of yearly maximum, median, first quartile, third quartile, interquartile range and mean of the daily sunspot area and magnetic flux on the solar full disc and found their maxima and minima for sunspot area and magnetic flux. Maxima occur in the years 2014 and 2015 for sunspot area and magnetic flux, respectively, whereas their minima occur in the years 2018 and 2019. We found the correlations between the descriptive statistical measures of sunspot area and magnetic flux, kernel density estimator, and lognormal functions to describe the distributions of daily sunspot area and magnetic flux. We found a positive correlation of 0.96 between the distribution functions of sunspot area and magnetic flux on the solar full disc during 2011 – 2023. We demonstrated that the distribution function for daily sunspot area correlates linearly well with the distribution function for magnetic flux during 2011 – 2023.
