We use current cosmic microwave background data to constrain cosmological parameters. The results are presented as confidence regions in the (Ω--Ho) -- plane for both open and flat geometries, and are based on a χ2 minimization to the power spectrum. Although such an approach does not strictly apply to power spectrum estimates, the results should nonetheless be indicative. We find that purely open, low--Ω models are strongly disfavored, due to the position of the ``Doppler Peak'' at high l; flat models are less strongly constrained. The parameter space explored is the largest to date, covering Ω, Ho, n, Q and ΩB h2.
