Technical data for this type of fractal : click here (JULIA-02).

Here :
real of c = -0.56588419, imaginary of c = 0.64363257
bailout test = mod, bailout value = 4

If the bailout test = mod and the bailout value = 1 instead of 4, the fractal looks like this :



With the same paramaters but with another palette of colors, the factal looks like this :



If the bailout test = and, and the bailout value = 2, the fractal looks like this (with the initial palette of colors) :
