From the analysis of the motions of sunspot groups recorded at Catania Astrophysical Observatory over a 7-years period from 1972 to 1978 the mean angular velocity as a function of latitude and age is calculated. The results suggest that the age of photospheric tracer (sunspot groups) affects the rotation curve slope. The implications of this result are discussed.

Abstract
From the analysis of the motions of sunspot groups recorded at Catania Astrophysical Observatory over a 7-years period from 1972 to 1978 the mean angular velocity as a function of latitude and age is calculated. The results suggest that the age of photospheric tracer (sunspot groups) affects the rotation curve slope. The implications of this result are discussed.File in questo prodotto:
