"Paper I, An Overview” by Robert M. Wilson (ST13) has been published in the Journal of the Alabama Academy of Science, Volume 91(2), pp. 99-115, November 2020. Examined are annual values of sunspot number (SSN), corrected sunspot area (SSA), number of active region entries (NARE), largest observed area active region (LAAR), mean area per entry (MAE), highest latitude spot (HLS), and inferred correlations between selected parameters based on the observed data for the years 1875–2017. A number of ±1 standard error of measurement prediction intervals are made regarding the size and timing of the current sunspot cycle (SC) SC25.
