Polarization results from the Cosmic Anisotropy Polarization MAPper (CAPMAP) experiment are reported. These are based on 433 hr, after cuts, observing a 2 deg2 patch around the north celestial pole with four 90 GHz correlation polarimeters coupled to optics defining 4′ beams. The E-mode flat band-power anisotropy within l = 940-300+330 is measured as 66-39-53 μK2; the 95% confidence level upper limit for B-mode power within l = 1050 -520+590 is measured as 38 μK2.
