The sunspot number is the primary record for solar variability over the last 400 years and constitutes a benchmark in solar/stellar variability studies and especially the Earth climate. While the Sunspot Number has been recalibrated recently (Clette, 2016), it can still be improved with a full reconstruction from the raw data. Now that more and more historical raw sunspot data are being made available through a collective effort of the community, it is time to make it accessible to the many researchers and users outside of the sunspot community. FARSuN will make the raw historical sunspot data [1610-1980] Findable and Accessible for all users.
