Sunspots have been systematically observed since 1610, after the invention of the telescope. In fact, the sunspot counting is considered like the world’s longest-running experiment. The sunspot number index is calculated from the number of sunspot appeared on the solar disc and it is the most used index to study the long-term solar activity. Recently, several problems were detected both in the sunspot number and the sunspot group databases. Therefore, they need a revision.
Nowadays, those problems are being addressed by the international community of space climate. In this presentation, several sunspot observation series made by amateur astronomer are presented highlighting their role in the recalibration of the sunspot number index in terms of their long-term stability in comparison with professional observatories working in a shift. Some of these observers with long observational series are David Hadden (U.S.A), Strach (United Kingdom) and Koyama (Japan). These contributions will play a key role to revise sunspot number and its extension to 14th century and beyond, on the basis of cosmogenic isotope with calibration of this index.
Artificial Intelligence has experienced a massive increase of interest, both to conduct fundamental research and to improve every-day applications. However, to scientists and the public, artificial intelligence remains opaque and hence causes a sceptical attitude.
Therefore, we are conducting public lectures to explain the principles of AI to the public, the opportunities and risks, and to engage them in programming their own AI-based classification algorithms. Eventually, we plan to develop a series of public lectures to train interested citizens to use AI methods to support fundamental research. In this presentation, I will talk about the main idea and applications of AI for astrophysical research, and present our strategy to develop a citizen science project: “Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.”, Marie Curie
