Vijf opnames van zonnevlekken door het observatorium van Catane before 1899

This artwork, "Vijf opnames van zonnevlekken door het observatorium van Catane," is a collection of five photographic plates, likely made before 1899, by MM. Ch. Fiévez. Each plate shows a different sunspot, a dark region on the surface of the sun, captured by the observatory in Catania, Italy. The plates are a valuable document of the sun's activity, offering a glimpse into the dynamic nature of our nearest star. These photographs contribute to the growing body of scientific knowledge about solar phenomena, particularly sunspot cycles.
