This paper discusses the gravitational radiation that accompanies the formation of a rotating protoneutron star. Mainly large-scale entropy inhomogeneities develope inside the star. As a result, bubbles of hot nuclear substance are formed, and convective motions arise: bubbles of hot neutron matter float to the surface of the star, while cold matter sinks to its center. Such large-scale motions of material give rise to an inhomogeneous mass distribution inside the star. Variable asymmetry appears in the mass distribution, and this causes gravitational radiation.
