The X-ray emission from the core of the Perseus cluster (Abell 426) has been observed in the 2--10 keV energy band by the rotating modulation collimator on the SAS 3 X-ray observatory. The X-ray data imply a diffuse source (L/sub chi/approx.5 x 10/sup 4/4 ergs s/sup -/1, FWHM approx.3'-5') and are consistent with but do not require the presence of a coincident, compact source (L/sub chi/approx.10/sup 4/4 ergs s/sup -/1). The centroid of the X-ray emission is also coincident with the radio nucleus of NGC 1275 (3C 84A). Synchro/Compton and hot-plasma models, when applied to radio-IR-visible spectral data, predict X-ray fluxes consistent with our data.
