He was a well-known pioneer in solar physics due to his theories and observations. Secchi published Le Soleil (The Sun) a summary of knowledge about our star in that time. Moreover, he published in this book his sunspot and prominence observations made during the period 1871-1875. In this work, we present a machine-readable version of these observations and a preliminary analysis of them.ELETTRONICOenArticle10.1051/swsc/20210332-s2.0-85117866030https://www.swsc-journal.org/articles/swsc/full_html/2021/01/swsc210057/swsc210057.htmlhttps://api.elsevier.com/content/abstract/scopus_id/85117866030
