Verificación de la posición del eje de rotación de la fotósfera solar basada en la estadística de manchas

Abstract

Verificación de la posición del eje de rotación de la fotósfera solar basada en la estadística de manchas %B 100 years after R.C. Carrington's determination (1863), up to date statistics are employed for the verfiication of the position of the solar photosphere rotation axis. The four years already processsed show axis angle eerors of tenths of degree. This method consists of calculating Fourier series order 1 terms and to give them an adequate shape for the proposed end, under the assumption that, if there is an error, the angle between the spots path in one date and Crrington's paralell in a whole turn around the Sun, should statistically be a sinusoid with a maximum elongation that is equal to the error, and an origin (or phase) equal to the length of the plane containing the error angle over the ecliptic.
