Query: CBR Anisotropy in an Open Inflation, CDM Cosmogony   We compute the cosmic background radiation anisotropy, produced by
energy-density fluctuations generated during an early epoch of inflation, in an
open cosmological model based on the cold dark matter scenario. At $\Omega_0
\sim$ 0.3 -- 0.4, the COBE normalized open model appears to be consistent with
most observations.
