USET Groups

USET Groups Values in the USET sunspot group catalog are derived from the solar drawings obtained by the Uccle Solar Equatorial Table (USET) facility that is located at the Royal Observatory of Belgium. The USET sunspot group catalog covers 82 years of observations in 2021, and is updated every day. A home-made software (DigiSun) written in Python is used to derive quantities such as location and areas from the sunspot drawings.
