Abstract
We compute the angular power spectrum of temperature anisotropies on t he microwave sky in the cosmic texture theory, with standard recombina tion assumed. The spectrum shows ''Doppler'' peaks analogous to those in scenarios based on primordial adiabatic fluctuations such as ''stan dard cold dark matter,'' but at quite different angular scales. There appear to be excellent prospects for using this as a discriminant betw een inflationary and cosmic defect theories.
