BSC1.swf - BSC1z.swf : The first example of the specific equations undergoing the catastrophe was given by
N. Gavrilov and A. Shilnikov:
(1). dx/dt = x (2+μ-β(x2+y2))+z2+y2+2y
(2). dy/dt = -z3-(1+y)(z2+y2+2y)-4x+μy
(3). dz/dt = (1+y)z2+x2
where β varies between 0.18 and 10, and μ=0.456, η=0.0357
A bleu sky orbit underlying catastrophe, i.e. blue sky bifurcation. For [z,y,x]. (Azimut=0, Elevation=0). (1'' 05')
