In the closed case, the CMB temperature anisotropy ${ΔT/T}$ generated by scalar perturbations is enhanced for low multipoles. It is argued that in the open case there is no suppression of low multipoles. A possibility of the existence of a preferred space direction in the open case is noted.8 pages, latex, no figuresAstrophysicstext
