Locarno Specola Solare Ticinese

The Specola Solare Ticinese (SST : https://www.specola.ch/en/home-english/) is the pilot station of the SILSO network. It  has digitized and archived  the sunspot observations and data collected at the Specola Solare Ticinese station in Locarno. This was done in a 5 year project financially supported by the Federal Office of Meteorology and Climatology MeteoSwiss, in the framework of GCOS Switzerland (https://www.meteoswiss.admin.ch/about-us/research-and-cooperation/international-cooperation/gcos/swiss-gcos-office.html) and in collaboration with ETH-Zurich University Archives (https://library.ethz.ch/en/archiving-and-digitising/archiving/eth-zurich-university-archives.html)  
 
An important result of this project is the recent publication on ZENODO of the sunspot group database that you can find at the following link: https://doi.org/10.5281/zenodo.8117331
 
In addition, SST and IRSOL (https://www.irsol.usi.ch) also developed an interactive WEB interface to look at these data https://sunspots.irsol.usi.ch/
