"Página Solar Jean Nicolini" é o novo nome da Seção Solar da REA/Brasil. Este site é dedicado a mostrar suas tarefas na observação amadora do Sol e a exibir alguns resultados obtidos por seus membros. Mesmo pertencendo a uma pequena rede observacional, os observadores solares têm desenvolvido esforços para cobrir eventos solares em base amadora, em especial os Eclipses Solares Totais, a contagem do número de Wolf, e a elaboração do Diagrama de Maunder.
"Solar Page Jean Nicolini" is a new name, formerly REA/Brasil Solar Section. This site is dedicated to show its observational tasks on amateur solar observation and to release some results reached by the members. Although belonging to a little observational network, the solar observers made efforts to do solar events coverage in an amateur basis, specially the Total Solar Eclipses, the Wolf Number count and the Maunder Diagram graphic.
