ABSTRACT: Based on the characteristics of sunspots, we propose the nonlinear chaos model of sunspot, which is similar Lorenz butterfly. Further, some cases of sunspot are discussed by the qualitative analysis theory of the nonlinear equations. Moreover, this model and method of sunspot may be corrected and developed from astrophysics and mathematics, for example, it may combine the general magnetic field model of sunspot.
