Conferencia; IAU Commission 12; 2016

Commission 12 of the International Astronomical Union encompasses investigationsof the internal structure and dynamics of the Sun, the quiet solar atmosphere, solarradiation and its variability, and the nature of relatively stable magnetic structures likesunspots, faculae and the magnetic network. The Commission sees participation of over300 scientists worldwide.The IAU-wide re-organization effort of the last few years has resulted in the creationof 35 new Commissions providing a more up-to-date representation of contemporaryastronomy. The three existing Commissions of Division E ?Sun and Heliosphere? havebeen confirmed in existence with essentially unaltered scope, but their designation hasbeen changed following the new convention that reflects their affiliation with a parentDivision. Hence, the ?historical? C12, C10 and C49 are now identified as C.E1 (SolarRadiation and Structure); C.E2 (Solar Activity); C.E3 (Solar Impact throughout theHeliosphere). In view of this designation change, we provide here below a brief history ofCommission 12 throughout its over 50 years in existence.
