Description
The reconstruction of the Sunspot Number (SN) series is a cornerstone for long-term solar activity studies and space climate research. In recent years, the exploitation of historical solar observations has proven essential for identifying inconsistencies, improving calibration, and extending the SN record. This presentation reviews recent advancements in the use of historical documents—such as early telescopic drawings, textual records, and neglected archival sources—to refine the SN series. We will discuss current efforts to reanalyze past observations of the solar disk, highlight outstanding tasks and challenges for the community, and show how these studies contribute to better solar activity reconstructions and predictions. Additionally, we will explore the impact of this work on science communication and education. Preliminary results from ongoing, unpublished research will also be presented to foster discussion and collaboration.
