Abstract

A new semiempirical model of photospheric faculae is presented in tabular form. The magnetic field is estimated from horizontal pressure equilibrium without tension forces. The geometry of the flux tube is determined from this estimated magnetic field and an assumed flux of 4.4 x 10 to the 17th gauss sq cm. The model is discussed in relation to recent observations.
