Resumen

Abstract

he present study was focused on the analysis of the solar radiation in a period from 2003 to 2020, using daily satellite data provided by SORCE (Solar Radiation and Climate Expe- riment) in different bands and GOES (Geostationary Operational Environmental Satellite) in X-rays; together with the records of the number of sunspots and class C, M and X events. An analytical comparison is performed to understand the possible factors that produce the variability of the solar cycle and another with the help of artificial intelligence more preci- sely automatic learning with classification neural networks. The data were compiled with an input data matrix of 24 × 6075 and labeled with respect to three binary outputs, A quiet Sun, B Sun with moderate activity and C Sun with strong activity. The results obtained show a correlation of 90.3 % agreement of all the data. The 48.1 % of the data have a behavior of quiet Sun, 41.3 % present a moderate solar activity and 1.0 % sun with strong activity.
