We report on observations of the Cosmic Microwave Background (CMB) obtainedduring the January 2003 flight of Boomerang . These results are derived from195 hours of observation with four 145 GHz Polarization Sensitive Bolometer(PSB) pairs, identical in design to the four 143 GHz Planck HFI polarizedpixels. The data include 75 hours of observations distributed over 1.84% of thesky with an additional 120 hours concentrated on the central portion of thefield, itself representing 0.22% of the full sky. From these data we derive anestimate of the angular power spectrum of temperature fluctuations of the CMBin 24 bands over the multipole range (50 < l < 1500). A series of features,consistent with those expected from acoustic oscillations in the primordialphoton-baryon fluid, are clearly evident in the power spectrum, as is theexponential damping of power on scales smaller than the photon mean free pathat the epoch of last scattering (l > 900). As a consistency check, thecollaboration has performed two fully independent analyses of the time ordereddata, which are found to be in excellent agreement.
