Abstract: We have compiled information and data on solar spectroheliographic observations in Madrid during 19121917. We have created a database with information on 829 flocculi specifying heliographic position, dates of observation, angular velocity, and typology. We analyze the reliability of the data by reconstructing the butterfly diagram, active longitudes, and flocculi typology.
