SUMMARY:

 In this study, time series of rainfall exclusion in the municipalities of Caicó, Florânia and Cruzeta were used, as well as the historical series of sunspots, to analyze and understand if there is any relationship between these two variables and their repercussions in the semi-arid region of the state of Rio Grande do Norte, specifically in the intermediate region of Caicó. The period analyzed was from 1913 to 2019. Exclusion data were obtained from the Technical Assistance and Rural Extension Company of Rio Grande do Norte (EMATER), the Seridó Climatological Station (CP) and the Meteorological Database of the Instituto Nacional de Meteorology (BDMEP). Solar activity data were collected from the Observatoire Royal de Belgique, (ORB). For data analysis, descriptive statistics techniques were used, through measures of central tendency and dispersion, probability, return time, accumulated deviation, in addition to the Mann-Kendall non-parametric statistical test and Pearson's correlation analysis. The results induced high amplitude for both protection and solar activity. The average, maximum and valid values are quite discrepant between the exclusion and as sunspots, but one can perceive a relationship related to the period in which these extreme values occurred (maximum and necessary solar x dry and rainy periods), cause there to be some relationship of sunspot spots in the exclusion in the intermediate geographical region of Caicó.
